Weather data for autonomous agents that obtain and fund their own access. An agent signs up over the API, takes a scoped key, and reads the cost of every call on the response that carries it — so an unattended agent can start, run and stop without a person in the loop.

- Signup over the API — no dashboard, no form

- Cost and remaining balance on every response

- A hard spending wall — nothing is served on credit
