Implementation notes
When to use MeteoSource
MeteoSource is worth evaluating when you need ML-corrected forecasts with finer local detail than raw GFS or ECMWF output. Its free tier of 400 calls/day is tight but workable for a single-location widget that caches the response for an hour.
Common pitfalls
- The `demo` key is tied to a single place ID (`london`). Using any other `place_id` value with the demo key returns a 401. Register for a real free key before writing integration code.
- The API uses MeteoSource's own `place_id` identifiers, not city names or coordinates directly. The `/find_places_prefix` endpoint resolves a city name to a place ID, adding a lookup step that costs one of your 400 daily calls.
- Sections of the forecast response (`current`, `hourly`, `daily`) must be explicitly requested via the `sections` parameter. Omitting it returns only `current` data — a different default than most weather APIs which return a bundled response.
- Free tier is restricted to the `v1/free/` endpoint path. The `v1/` path (without `/free/`) requires a paid key and returns a 402 without a descriptive error if you accidentally use it.
