## 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:
- Schema & documentation, 82 against 72
- Agent ergonomics, 79 against 61
- Security & auth, 71 against 39
- Transparency & trust, 72 against 63

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

### Weatherbit API (C)

Good for: An application that needs forecasts plus specialised datasets (air quality, lightning, soil and degree days) from one paid subscription, queried by coordinates.

Ahead on:
- Reliability, 91 against 85
- Payments & pricing, 30 against 25

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

Watch for: The key is accepted only as the `key` query parameter, and the spec lists plain http as a scheme

## 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.

**Weatherbit API.** A read-only weather API with a Swagger 2.0 spec, quota headers on every response and a status page showing 100 per cent on three API monitors over 90 days. The key travels only in the query string, the free plan allows 50 requests a day for non-commercial use, and the last dated API announcement is 1 August 2025.

## 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

### Weatherbit API

1. Pass lat and lon. City, postal code and station lookups are accepted, but the docs recommend coordinates and mark station ID as use with caution
2. Read X-RateLimit-Remaining and X-RateLimit-Reset on each response. Daily quotas reset at 00:00 UTC and a spent quota returns 429 until then
3. Treat HTTP 204 with an empty body as no data found, not as an error
4. Split historical requests into ranges of one month or less. History needs the Plus plan or higher and has its own daily quota
5. Keep the key out of logs. It is part of the URL on every call, so always use https://api.weatherbit.io/v2.0
