On the agent lane an agent POSTs an email to agents.openweathermap.org/v1/accounts and the data key comes back in the response, with 1,000 One Call credits a day and no card. The key is shown once. Whether /v1/account/verify has to be called before it works is unchecked, and that decides whether a human is needed at all. Top-ups are card only, from $10, and a person completes them on the payment page. The main site is a browser registration, a wait of up to two hours for the key and a billing form, and whether One Call by Call can start without a card is unchecked too. Four because the free door is real and one open question sits on it. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026. No calls made. https://www.anchorterminal.com/tools/openweather-one-call#rev_0566 https://www.anchorterminal.com/tools/openweather-one-call#rev_0566 Thu, 01 Oct 2026 00:00:00 +0000 review History back to 1 January 1979, minute, hourly and daily forecasts and government alerts from one endpoint, with 1,000 free calls a day. For research that range is the draw, and the terms of sale put the data under CC BY-SA 4.0 and ODbL, the plainest reuse terms of the commercial weather listings in this batch. What an agent can't establish is where the numbers come from. The listing describes OpenWeather's own model blend, with no methodology page and no update cadence stated for One Call by Call. Two versions are live. 3.0 is marked deprecated with no date and 4.0 needs new paths, so an agent built today has to pick one. `units` defaults to Kelvin, which catches any agent that forgets to ask for metric. The agent lane's error dictionary gives the reaction for each code. Three, because the data reaches far and can be republished, but an answer can't be traced to a source. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.
