## Which one, for what

### 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:
- Schema & documentation, 77 against 67
- Agent ergonomics, 66 against 54
- Payments & pricing, 34 against 20
- Maintenance & community, 57 against 36
- Transparency & trust, 61 against 49

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

### The Weather Company Data APIs (D)

Good for: A business that wants one contract for global forecasts, 4 km current conditions, alerts, imagery, aviation and deep history, and that can go through sales.

Watch for: No self-serve signup. The trial is requested through a form, is limited to enterprise customers, and the Buy now button opens a contact form.

## Verdicts

**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.

**The Weather Company Data APIs.** A wide weather data API with 168 API references built from OpenAPI documents, global 4 km current conditions, hourly history from June 2015 and a status page with component history. Keys come only through a sales-reviewed trial or contract, travel only in the URL, and the terms that govern the API are not published.

## Before you call either

### 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

### The Weather Company Data APIs

1. Send `units`, `language` and `format=json` with a location on every v3 call, plus `Accept-Encoding: gzip`, which the usage guide marks as required.
2. Keep the key out of logs and client-side code, because it travels in the query string as `apiKey`.
3. Treat a 401 as either a bad key, an endpoint outside the key's package or an exceeded limit, and treat a 204 as no data for the query.
4. Each forecast duration (`3day` to `15day`) is a separate entitlement. Request only durations the contract covers.
5. Use `/v3/aggcommon` to combine up to 10 products in one request. Each product and each location still counts as one call.
