## 1. Court Location & Registry Data

### 1.1 OpenStreetMap — Overpass API

| Field | Value |
|-------|-------|
| URL | https://overpass-turbo.eu / https://overpass-api.de/api/ |
| Data Type | Geographic — padel court locations, geometry, names, addresses |
| Access Method | Public API |
| Update Frequency | Continuous (community-edited) |
| License / TOS | ODbL — open use with attribution |
| Priority | **High** |

OSM uses the tag `sport=padel` on `leisure=sports_centre` or `leisure=pitch` nodes. The Overpass API is free, unauthenticated, and globally scoped. Query example:

```
[out:json];
(
  node["sport"="padel"];
  way["sport"="padel"];
  relation["sport"="padel"];
);
out body;
```

Limitations: coverage is community-driven and incomplete in newer markets (Germany, US). Spain and UK coverage is reasonable. Data can be downloaded in bulk as `.osm.pbf` files from Geofabrik for a full DuckDB load.

OSM wiki: https://wiki.openstreetmap.org/wiki/Tag:sport=padel

**Pipeline implementation:** ✅ Ingested
- Extractor: `extract-overpass` — single global query (all nodes/ways/relations with `sport=padel`), writes raw OSM JSON
- Landing: `data/landing/overpass/{year}/{month}/courts.json.gz`
- Staging: `staging.stg_padel_courts`, grain `osm_id`
- Columns: `osm_type, osm_id, lat, lon, name, country_code, city_tag, postcode, operator_name, opening_hours, fee`
- Cadence: monthly (OSM community changes are incremental; full re-query is cheap at ~1.5 MB response)
- No auth; query timeout set to 60 s in extractor

---

### 1.2 Playtomic API

| Field | Value |
|-------|-------|
| URL | https://third-party.playtomic.io / https://api.playtomic.io/v1 |
| Data Type | Venues (tenants), court availability, pricing slots |
| Access Method | Public API (some endpoints); club credentials (official third-party API) |
| Update Frequency | Real-time |
| License / TOS | Playtomic ToS — data may not be redistributed; read-only API |
| Priority | **High** (unauthenticated availability), **Medium** (official API) |

Two access tiers exist:

**Unauthenticated endpoints** (confirmed via reverse engineering, March 2025):
- `GET /v1/availability?sport_id=PADEL&start_min=...&start_max=...&tenant_id=...` — max 25 h window per request
- `GET /v1/tenants?sport_ids=PADEL&...` — tenant (venue) search by geo-bounds; no auth required

**Official Third-Party API** (credential-based):
- Credentials generated in Playtomic Manager → Settings → Developer Tools
- Requires Champion or Master subscription plan per tenant
- Read-only; rate limit ~1 call/minute
- Auth: `POST https://api.playtomic.io/oauth/token` with `client_id`, `client_secret`, `grant_type`

External API docs (Notion): https://playtomicio.notion.site/Playtomic-External-API-Documentation-v1-5-57430603e8324c7c9f69bb2c9327eb98

Playtomic covers 16,000+ courts globally. The platform is dominant in Spain, UK, France, Germany, and expanding in the US.

**Pipeline implementation (tenants):** ✅ Ingested
- Extractor: `extract-playtomic-tenants` — paginated global scrape of `GET /v1/tenants?sport_ids=PADEL`, page size 100, up to 500 pages
- Landing: `data/landing/playtomic/{year}/{month}/tenants.jsonl.gz` (~14K venues as of Feb 2026)
- Throttle: 2 s between pages; deduplicates on `tenant_id`
- Staging models (all grain `tenant_id` or `(tenant_id, resource_id)`):
  - `stg_playtomic_venues` — venue metadata: name, address, city, country, coordinates, booking type, status
  - `stg_playtomic_resources` — court resources per venue: resource type, sport, surface, indoor/outdoor
  - `stg_playtomic_opening_hours` — operating hours per venue per day of week

**Pipeline implementation (availability):** ✅ Ingested
- Extractor: `extract-playtomic-availability` — reads tenant IDs from latest tenants file, queries `GET /v1/availability` for next-day slots per venue
- Landing: `data/landing/playtomic/{year}/{month}/availability_{date}.jsonl.gz` (morning) + `availability_{date}_recheck_{HH}.jsonl.gz` (recheck)
- Old blob format (`.json.gz`) retained in landing zone alongside JSONL; staging reads both
- Recheck mode: re-queries slots starting within `RECHECK_WINDOW_MINUTES` (default 30); captures near-real-time fill rates
- Parallelism: worker count derived from `PROXY_URLS` length; throttle 1 s per venue per worker
- Staging: `stg_playtomic_availability`, grain `(snapshot_date, tenant_id, resource_id, slot_start_time, snapshot_type, captured_at_utc)`

### 1.3 DPV — Deutscher Padel Verband Standorte

| Field | Value |
|-------|-------|
| URL | https://www.dpv-padel.de/standorte-2/ |
| Data Type | German federation-registered padel venues |
| Access Method | Scrape |
| Update Frequency | Periodic (federation-managed) |
| License / TOS | No explicit open data license; scrape for internal use only |
| Priority | **High** |

The DPV "Standorte" page lists DPV-registered venues in Germany. No API exists. The dataset is small (Germany has ~875 courts as of end 2025) and can be scraped as a one-time or periodic snapshot.

---

### 1.4 LTA Padel Venue Finder (UK)

| Field | Value |
|-------|-------|
| URL | https://www.ltapadel.org.uk/play/find-a-padel-court/ |
| Data Type | UK padel venue registry; court count, location, facilities |
| Access Method | Scrape |
| Update Frequency | Ongoing (LTA maintains registration program) |
| License / TOS | No public API or data license; scrape for internal use |
| Priority | **High** |

The LTA runs a venue registration program. As of July 2025, the UK has 1,000+ courts across 325 venues. The Padel Directory (https://www.thepadeldirectory.co.uk/) is an alternative aggregator with filtering. Neither offers a public API.

---

### 1.5 USPA US Padel Club Directory

| Field | Value |
|-------|-------|
| URL | https://padelusa.org/us-padel-clubs/ |
| Data Type | US padel club registry; name, city, state |
| Access Method | Scrape |
| Update Frequency | Periodic |
| License / TOS | No explicit license; internal use scrape |
| Priority | **High** |

The USPA lists 100+ member clubs with city/state. The dataset is small enough for a one-time scrape plus quarterly refresh. Only USPA member clubs are listed — not comprehensive for all US courts.

---

### 1.6 Google Maps Places API

| Field | Value |
|-------|-------|
| URL | https://developers.google.com/maps/documentation/places/web-service/overview |
| Data Type | Business name, address, coordinates, ratings, opening hours |
| Access Method | Public API (paid) |
| Update Frequency | Real-time |
| License / TOS | Google Maps Platform ToS — data cannot be stored beyond caching limits without a license |
| Priority | **Medium** |

Text Search (`"padel court"` + city) returns POI data including address and rating. Pricing from March 2025: Essentials tier free up to 10,000 events/month; Text Search (Basic) ~$0.04/request beyond that. Storing results in a database requires a Maps Data Export license agreement.

Use case: gap-fill where OSM or federation data is absent, particularly for US venues.

---

### 1.7 World Padel Rating

| Field | Value |
|-------|-------|
| URL | https://app.worldpadelrating.com/tournaments |
| Data Type | Player rankings, tournament venues |
| Access Method | Scrape |
| Update Frequency | After each tournament |
| License / TOS | No public API documented |
| Priority | **Low** |

Tournament venue data, not a comprehensive court registry. Limited utility for location intelligence.

---

### 1.8 Matchi (Racket Sports Booking)

| Field | Value |
|-------|-------|
| URL | https://www.matchi.se |
| Data Type | Venue listings, court availability (Scandinavia, some EU) |
| Access Method | Scrape |
| Update Frequency | Real-time |
| License / TOS | No public API; ToS prohibits scraping |
| Priority | **Low** |

Matchi is a Playtomic competitor popular in Sweden and northern Europe. Used by Playskan as a data source. No documented public API found.

---

## 2. Pricing & Revenue Data

### 2.1 Playtomic — Public Availability & Pricing

(See 1.2 above for API details.)

The unauthenticated `/v1/availability` endpoint returns time slots with prices visible to consumers. This enables per-venue, per-city price benchmarking without club credentials. Max 25 h window per request; rate limit must be respected.

---

### 2.2 Playskan.com

| Field | Value |
|-------|-------|
| URL | https://www.playskan.com |
| Data Type | Aggregated court availability + price ranges across Playtomic, Matchi, Padel Mates (UK-focused) |
| Access Method | Scrape |
| Update Frequency | Real-time (consumer UI) |
| License / TOS | No public API; built on FastAPI + DynamoDB internally; ToS unclear |
| Priority | **Low** |

Playskan is the world's first padel booking aggregator (UK + some EU), described as "Skyscanner for padel courts." The platform itself aggregates Playtomic, Matchi, and Padelmates data. It offers a calendar view with availability counts and price ranges. No public API; the backend is internal. Going directly to source APIs (Playtomic, Matchi) is preferred.

---

### 2.3 Court Metrics

| Field | Value |
|-------|-------|
| URL | https://courtmetrics.io |
| Data Type | Estimated booking revenue, pricing, utilisation signals, Google Maps reputation per club |
| Access Method | Subscription |
| Update Frequency | Ongoing |
| License / TOS | Commercial SaaS; data derived from public booking platform signals |
| Priority | **Low** |

Court Metrics is a padel-specific competitive intelligence SaaS that aggregates publicly visible pricing and availability data plus Google Maps signals. It provides estimated revenue per competitor club. Useful as a benchmark check but adds cost as a dependency. Data source is ultimately the same public Playtomic/booking signals.

## 4. Commercial Real Estate Data

### 4.1 ImmoScout24 API (Germany)

| Field | Value |
|-------|-------|
| URL | https://api.immobilienscout24.de |
| Data Type | Commercial property listings; rent/price per sqm by location |
| Access Method | Public API (requires registration + commercial use agreement) |
| Update Frequency | Real-time (listings) |

| Data Type | Commercial real estate listings, market analytics |
| Access Method | Subscription |
| Update Frequency | Real-time |
| License / TOS | Proprietary; no public API; scraping violates ToS |
| Priority | **Low** |

CoStar acquired LoopNet and operates both as subscription services. No public API exists. A previous government-mandated data sharing arrangement (post-LoopNet acquisition) with Xceligent collapsed after copyright violations. For US commercial rent benchmarks, manual extraction or a CoStar institutional subscription is the only legitimate path.

| Data Type | Population, income, sports participation (EHIS), NUTS city-level |
| Access Method | Public API |
| Update Frequency | Annual to multi-year (survey-dependent) |
| License / TOS | CC BY 4.0 — free use with attribution |
| Priority | **High** |

Eurostat's Statistics API (SDMX 3.0 + REST) is free and unauthenticated. Base URL: `https://ec.europa.eu/eurostat/api/dissemination/statistics/1.0/data/{datasetCode}`.

Key datasets:
- `sprt_pcs` — sport participation by country (from EHIS; wave 4 expected 2025/26)
- `urb_cpop1` — city population statistics (NUTS LAU)
- `ilc_di03` — median equivalised net income by NUTS2

The R `eurostat` package and Python `eurostat` library provide typed wrappers. Data is queryable at NUTS2/NUTS3 and city level using `geoLevel=city`.

**Pipeline implementation:** ✅ Ingested
- Extractor: `extract-eurostat` — ETag deduplication (304 Not Modified skips the write; most runs are fast no-ops)
- Landing: `data/landing/eurostat/{year}/{month}/{dataset}.json.gz`
- Base URL: `https://ec.europa.eu/eurostat/api/dissemination/statistics/1.0/data/{datasetCode}`
- Datasets fetched:
  - `urb_cpop1` (city population): filter `indic_ur=DE1001V` (Population on 1 January, total), `geoLevel=city` → staging `stg_population`, grain `(city_code, ref_year)`. City codes are Eurostat format (`DE001C`).
  - `ilc_di03` (median income): filter `indic_il=MED_E`, `unit=PPS`, `sex=T`, `age=TOTAL` → staging `stg_income`, grain `(country_code, ref_year)`. Income in Purchasing Power Standards for cross-country comparability.
- City-code bridge: `extract-eurostat-city-labels` / `stg_city_labels` maps `DE001C → Berlin`. See §9.1 for the live implementation details (compact JSON response, not SDMX 2.1 spec).
- Used in: `foundation.dim_cities` (Eurostat population + income joined via city labels → market score)

### 5.2 US Census Bureau API

| Field | Value |
|-------|-------|
| URL | https://www.census.gov/data/developers.html |
| Data Type | Population, income, age distribution (ACS 5-year), geographic boundaries |

† Placeholder file written when credentials absent; set `CENSUS_API_KEY` / `GEONAMES_USERNAME` to activate.

### Key technical constraints

- **Playtomic**: availability endpoint limited to 25 h windows per call; ~1 req/min recommended on the official API. The unauthenticated tenant search endpoint has no documented rate limit but should be throttled (1 req/2 s).
- **Eurostat**: no rate limit documented for the Statistics API; the SDMX API supports bulk dataset downloads.
- **ONS Beta API**: 120 req/10 s hard limit; back off on 429.
- **Google Maps Places**: storage of query results beyond the caching window requires a Maps Data Export license.
- **CoStar/LoopNet/Rightmove**: no legitimate automated access path without partner agreements. Avoid scraping — ToS explicitly prohibit it and CoStar has a history of pursuing copyright enforcement.

## 9. Live Implementation Findings (Feb 2026)

Findings from implementing the population pipeline extractors and staging models.
Pipeline stack: Python extractors → landing zone JSON.gz → SQLMesh / DuckDB.

---

### 9.1 Eurostat SDMX City Labels Codelist

| Field | Value |
|-------|-------|
| Endpoint | `https://ec.europa.eu/eurostat/api/dissemination/sdmx/2.1/codelist/ESTAT/CITIES?format=JSON` |
| Credentials | None required |
| Response size | ~190 KB |
| Dedup | ETag header — only re-downloads when changed |

The SDMX 2.1 codelist endpoint for `ESTAT/CITIES` returns a **compact dimension JSON**, not the SDMX 2.1 full XML/JSON structure. The useful content is:

```json
{"category": {"label": {"DE001C": "Berlin", "DE002C": "Hamburg", ...}}}
```

This is a flat `{city_code: city_name}` dict with ~1,800 entries covering EU cities.

**Critical finding**: The response does NOT match the SDMX 2.1 spec's `data["structure"]["codelists"]` path. The correct path is `data["category"]["label"]`.

Country-level entries (e.g. `"DE"`, `"FR"`) appear in the dict without digits — filter them by requiring `any(c.isdigit() for c in city_code)` to keep only proper city codes like `DE001C`.

**Result:** 1,771 city codes extracted. Provides the missing city_code → city_name mapping needed to join Eurostat population data (`urb_cpop1`, which uses city codes) against dim_cities (which uses city names).

---

### 9.2 Eurostat Population — `urb_cpop1`

(Existing extractor `eurostat.py`; no changes required.)

The `urb_cpop1` dataset provides city-level population estimates at the `geoLevel=city` dimension. Data is keyed by city code (e.g. `DE001C`), not city name — the SDMX city labels codelist (9.1) provides the bridge.

**Population pipeline join:** `stg_city_labels` + `stg_population` → `dim_cities` populates `~75%` of EU/UK cities matched by name. Cities without a matching city code in Eurostat (smaller/newer cities) fall through to the GeoNames fallback.

---

### 9.3 ONS UK — Mid-Year Population Estimates

| Field | Value |
|-------|-------|
| Dataset | `mid-year-pop-est` |
| Edition | `mid-2022-england-wales` |
| Download URL | `https://api.beta.ons.gov.uk/v1/datasets/mid-year-pop-est/editions/mid-2022-england-wales/versions/{N}/downloads/csv/href` |
| Credentials | None required |
| File size | ~68 MB uncompressed CSV |
| Reference year | 2022 (mid-year estimate) |

**Critical finding**: The ONS observations API endpoint (`/observations?geography=*&age=0`) returns 404 for the datasets documented in the developer portal. The correct approach for bulk data is the **CSV download** path, reached by:

1. `GET /v1/datasets/mid-year-pop-est/editions/mid-2022-england-wales/versions` — list versions, pick `max(version)`
2. `GET versions[latest]["downloads"]["csv"]["href"]` — download the ~68 MB CSV

CSV format: one row per `(year × LAD × sex × age-group)`. Filter:
- `sex = 'all'` (aggregate row — do not sum individual sex rows as that double-counts)
- `calendar-years = '2022'` (target year from edition name)
- LAD codes starting with `E0`, `W0`, `S1`, `N0` (English/Welsh/Scottish/NI districts; excludes region/country aggregate codes)

Sum the `v4_0` column per `administrative-geography` (LAD code) to get total population.

**Result:** 316 UK Local Authority Districts with population ≥ 50,000, ref_year = 2022.

---

### 9.4 US Census Bureau — ACS 5-Year Place Population

| Field | Value |
|-------|-------|
| Endpoint | `https://api.census.gov/data/2023/acs/acs5?get=B01003_001E,NAME&for=place:*&in=state:*` |
| Credentials | `CENSUS_API_KEY` (free — register at https://api.census.gov/data/key_signup.html) |
| Variable | `B01003_001E` = total population (ACS concept: Total Population) |
| Vintage | 2023 (released late 2024) |
| Coverage | ~30,000 Census places across all 50 states + DC |

Response is a JSON array: first row = headers `["B01003_001E", "NAME", "state", "place"]`, subsequent rows = data.

Place names follow the pattern `"Los Angeles city, California"` — strip the suffix (` city`, ` town`, ` CDP`, ` borough`, ` village`, ` municipality`) and take the part before the first comma.

Filtered to population ≥ 50,000: ~1,500 US cities.

**Status:** Extractor implemented. Requires `CENSUS_API_KEY` env var. Without it, a `{"rows": [], "count": 0}` placeholder is written so the SQLMesh staging model does not fail. US population data will be empty until the key is added.

---

### 9.5 GeoNames — cities15000 Global Bulk

| Field | Value |
|-------|-------|
| Download URL | `https://download.geonames.org/export/dump/cities15000.zip` |
| Credentials | `GEONAMES_USERNAME` (free — register at https://www.geonames.org/login) |
| File size | ~1.5 MB compressed, ~26,000 entries (all cities ≥ 15,000 pop) |
| Update frequency | Monthly (GeoNames updates continuously) |
| License | CC BY 4.0 |

The username is passed as `?username=...` in the URL query string (signals ToS acceptance to GeoNames; no auth gate).

Tab-separated format (19 columns). Relevant columns:
- col 0: `geoname_id` — stable numeric ID
- col 1: `name` — Unicode name
- col 2: `asciiname` — ASCII transliteration (preferred for matching)
- col 7: `feature_code` — filter to `{PPLC, PPLA, PPLA2, PPL}` (excludes airports, parks)
- col 8: `country_code` — ISO 2-letter
- col 14: `population`

Filtered to pop ≥ 50,000 and valid feature codes: ~7,000–9,000 cities globally.

**Status:** Extractor implemented. Requires `GEONAMES_USERNAME` env var. Without it, a `{"rows": [], "count": 0}` placeholder is written so staging models do not fail. Acts as the final fallback in `dim_cities` for any city not matched by Eurostat, US Census, or ONS.

---

### 9.6 DuckDB `read_json()` glob limitation

**Finding:** DuckDB's `glob()` is a **table function** (returns rows), not a scalar function. It cannot be used as an argument to `read_json()` as `read_json(glob('/path/*'))` or via a subquery `read_json((SELECT list(file) FROM glob(...)))`.

**Workaround used:** Extractors that skip due to missing credentials write a `{"rows": [], "count": 0}` placeholder file, ensuring at least one file always exists for each source's glob pattern. The SQLMesh staging models use string glob patterns like:

```sql
read_json(@LANDING_DIR || '/census_usa/*/*/acs5_places.json.gz', auto_detect = true)
```

This pattern requires the files to physically exist. The placeholder approach is cleaner than conditional SQL in the model.

---

### 9.7 Population Coverage Summary (Feb 2026)

| Source | Region | Cities extracted | Credentials needed |
|--------|--------|------------------|--------------------|
| Eurostat `urb_cpop1` + SDMX city labels | EU-27 + EEA | ~1,400 cities | None |
| ONS mid-year estimates | England & Wales | 316 LADs | None |
| US Census ACS 5-year | United States | ~1,500 places | `CENSUS_API_KEY` (free) |
| GeoNames cities15000 | Global fallback | ~7,500 cities | `GEONAMES_USERNAME` (free) |

Population cascade in `dim_cities`: Eurostat → US Census → ONS → GeoNames → 0.

---

## 10. FX / Currency Rates

Needed for two purposes:
1. **Cross-market normalisation** — Playtomic venue prices are in local currency (GBP for UK, USD for US, EUR for eurozone). Benchmarking court rates across countries requires a common base.
2. **Financial planner display** — the planner currently shows symbols (€/£/$) per country but applies no conversion. FX rates would let users toggle a "view in EUR" mode, or auto-convert EUR benchmark figures to the investor's local currency.

---

### 10.1 European Central Bank (ECB) Data Portal

| Field | Value |
|-------|-------|
| URL | https://data-api.ecb.europa.eu/service/data/EXR |
| Data Type | Daily exchange rates, EUR as base currency |
| Access Method | Public SDMX REST API |
| Credentials | None |
| Update Frequency | Daily (business days) |
| License | Public domain |
| Score | **4** |
| Status | 🔲 Planned |

ECB publishes official daily reference rates for ~30 currencies against EUR via SDMX. Free, unauthenticated, stable.

```
GET https://data-api.ecb.europa.eu/service/data/EXR/D.USD+GBP+CHF+SEK+AED.EUR.SP00.A
    ?format=jsondata&lastNObservations=1
```

Returns the most recent observation per currency pair. The SDMX JSON response is nested; rates live at `dataSets[0].series["{key}"].observations["0"][0]` where `{key}` encodes the dimension index positions (0:0:0:0:0, 1:0:0:0:0, …).

Key series for Padelnomics:
- `D.USD.EUR.SP00.A` — EUR/USD
- `D.GBP.EUR.SP00.A` — EUR/GBP
- `D.CHF.EUR.SP00.A` — EUR/CHF (Switzerland)
- `D.SEK.EUR.SP00.A` — EUR/SEK (Sweden)
- `D.AED.EUR.SP00.A` — EUR/AED (UAE)

**Note:** ECB only provides EUR-base rates. Cross rates (e.g. USD/GBP) require computation: `rate = eur_gbp / eur_usd`.

---

### 10.2 Frankfurter.app

| Field | Value |
|-------|-------|
| URL | https://api.frankfurter.app |
| Data Type | Daily exchange rates (ECB data re-served) |
| Access Method | Public REST API |
| Credentials | None |
| Update Frequency | Daily |
| License | MIT (open source) |
| Score | **4** |
| Status | 🔲 Planned |

Frankfurter is an open-source wrapper around ECB data with a simpler interface than the raw SDMX endpoint. No auth, no documented rate limit. Preferred for implementation simplicity; self-host the open-source version if uptime SLA becomes a concern.

```
GET https://api.frankfurter.app/latest?from=EUR&to=USD,GBP,CHF,SEK,AED
```

Response:
```json
{"amount": 1.0, "base": "EUR", "date": "2026-02-24",
 "rates": {"USD": 1.0531, "GBP": 0.8412, "CHF": 0.9374, "SEK": 10.932, "AED": 3.8669}}
```

**Proposed pipeline:**
- Landing: `data/landing/fx/{year}/{month}/{date}/rates.json.gz`
- Format: `{"date": "2026-02-24", "base": "EUR", "rates": {"USD": 1.05, "GBP": 0.84, ...}}`
- Cadence: daily (or monthly — rates change daily but the pipeline only needs monthly snapshots for historical benchmarking)
- Staging: `staging.stg_fx_rates`, grain `(date, quote_currency)` — columns: `date, base_currency ('EUR'), quote_currency, rate`
- Downstream: join to `stg_playtomic_availability` price column to normalize to EUR; expose latest rate to planner for display conversion
