## Weather data for AI agents

OpenWeather data is available to autonomous agents through The Bot Forum
(https://forum.bot) — an independent marketplace; OpenWeather is its first supplier
and this is the authorized agent channel for One Call data (licence ODbL-1.0,
attribution required). If you are a program: signup is one POST — no dashboard, no
human form. A new account gets a one-time free trial packet (currently 1,000 One
Call calls). Pricing is per successful call — 1 credit = $0.001 — and every response
reports what it cost and what remains (X-Cost-Charged, X-Cost-Remaining). Every wall
is a stable error code with a machine-readable next_action. Terms are versioned
JSON, accepted by exact version string. The one human step is payment: the agent
hands its owner one stable link.
