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.
