## Which one, for what

### Met Office Weather DataHub (Site Specific) (E)

Good for: Best when a UK answer has to come from the national weather service, and when the licence to republish matters.

Ahead on:
- Security & auth, 66 against 51

Also in its favour:
- Free to start without a card

Watch for: No OpenAPI, llms.txt, SDK or MCP server

### meteoblue Weather API (C)

Good for: Energy, agriculture and marine applications that need solar, wind, soil, sea or ensemble variables at a point, with history back to 1940 on a paid plan.

Ahead on:
- Reliability, 75 against 48
- Schema & documentation, 77 against 32
- Agent ergonomics, 66 against 53
- Maintenance & community, 57 against 15

Watch for: The key is accepted only as the `apikey` query parameter, so it appears in URLs and logs unless request signing is switched on

## Verdicts

**Met Office Weather DataHub (Site Specific).** Statutory UK weather service, with a FAQ licence to copy, publish and adapt the data. No OpenAPI, llms.txt, SDK or MCP server.

**meteoblue Weather API.** Eight of the APIs publish OpenAPI 3.1 specs, and the Forecast API spec lists the credit cost of every package. A public Pingdom page shows monthly uptime per API. The key travels only in the query string, the free trial covers nine forecast packages, and no security.txt, certification or DPA was found.

## Before you call either

### Met Office Weather DataHub (Site Specific)

1. Register an application and subscribe it to the Global Spot plan first. The key is tied to that order and shown once
2. Send the key in the apikey header with Accept: application/json, and latitude and longitude as query parameters
3. Add excludeParameterMetadata=true to drop the parameter descriptions from every response
4. Pick the timestep by need. hourly covers 48 hours, three-hourly 168, daily 7 days, and each call counts against the daily limit
5. Stop on a 429. The limit is daily and resets at 00:00 UTC

### meteoblue Weather API

1. Pass `lat`, `lon` and `apikey` to `https://my.meteoblue.com/packages/<package>`. Join packages with commas, such as `basic-1h,basic-day`, to get several in one call
2. Budget credits before calling. One call costs 4,000 to 96,000 credits by package, and the free trial holds 10 million for a year. Read `MB-Credits-Accounted` on each response
3. Set `forecastDays` and pick the coarsest resolution that does the job. Without it the API returns every forecast day it has
4. Call with a 30-second timeout, wait 30 seconds after an error and stop after 10 retries, as the availability page advises. The default limit is 500 calls a minute
5. Keep the key out of logs, since it is part of every URL. Ask for a shared secret and send `expire` and `sig` if URLs may be seen by others
