## Which one, for what

### Google Weather API (Maps Platform) (B)

Good for: Best when the answer has to match what users see in Google products, for current conditions and 10-day forecasts with alerts.

Ahead on:
- Reliability, 85 against 75
- Schema & documentation, 82 against 77
- Agent ergonomics, 79 against 66
- Security & auth, 71 against 51
- Transparency & trust, 72 against 61

Watch for: History is 24 hours only, and bulk data isn't available

### 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:
- Payments & pricing, 34 against 25
- Maintenance & community, 57 against 20

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

**Google Weather API (Maps Platform).** Covered by the Maps Platform SLA, 99.9 per cent with service credits. History is 24 hours only, and bulk data isn't available.

**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

### Google Weather API (Maps Platform)

1. Ask for only the days or hours you need, one location a call. Every call is one billable event
2. Page with pageSize and pageToken rather than asking for 240 hours at once
3. Check the coverage page before promising alerts. Coverage is by country
4. Refetch rather than cache. The Maps terms give no caching window for weather content
5. Restrict the key to the Weather API and your server IPs in the Cloud console

### 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
