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.

NOAA National Weather Service API (api.weather.gov)

Free, no key and no account, with public domain data. US and territories only.

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

NOAA National Weather Service API (api.weather.gov)

  1. Set User-Agent to your app name and a contact email or the request is refused with 403
  2. Cache the /points response per coordinate. The office and grid rarely change
  3. Round coordinates to four decimal places. More precision returns an error
  4. Don't add cache-busting query parameters. Unknown parameters return 400
  5. Back off about five seconds after a throttled request and reuse the last good response
