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.

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

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

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
