Register an application and subscribe it to the Global Spot plan first. The key is tied to that order and shown once\n2. Send the key in the apikey header with Accept: application/json, and latitude and longitude as query parameters\n3. Add excludeParameterMetadata=true to drop the parameter descriptions from every response\n4. Pick the timestep by need. hourly covers 48 hours, three-hourly 168, daily 7 days, and each call counts against the daily limit\n5. Stop on a 429. The limit is daily and resets at 00:00 UTC\n\n### Tomorrow.io Weather API\n\n1. Send the key in the `apikey` header, not the query string, so it stays out of URLs and logs\n2. Request only the `fields` and `timesteps` needed on POST /timelines. Free plans cover 24 hours back and 5 days ahead at `1h` and `1d`\n3. Split archive requests. POST /historical takes at most 31 days per call and deducts tokens, 1 for a point and 10 for a polygon\n4. Treat 401 with code 401001 as a missing or bad key. The docs say 403, the live API answered 401 on 8 October 2026\n5. On 429 back off without a hint. `Retry-After` is documented only for 503\n6. Check the plan's terms before storing or reselling responses. Free accounts are limited to non-commercial use with a Powered by Tomorrow.io link\n\n## Questions\n\n### Which is better for AI agents, Met Office Weather DataHub (Site Specific) or Tomorrow.io Weather API?\n\nTomorrow.io Weather API scores 51.4 (D) on agent readiness against Met Office Weather DataHub (Site Specific)'s 45.5 (E), and leads in 5 of 7 scored categories.
