## How to call

API reference: https://agents.machina.gg/zcj/b99z9s9rpbo8/services/forecasts/openapi.json - consult this service’s spec for any operations, parameters, request bodies, or response schemas you still need. Shared operations retain selector values for all their services: each operation's `x-payment-info` names the service it bills by slug, and this service's slug is `forecasts`. The slug identifies the service in prices and usage reports only; never send it as a request value. When one operation serves several services, its request body schema lists the accepted values of the field that selects the service (a model id, for example): send one of those exactly as written.

Send your request to `https://agents.machina.gg/zcj/b99z9s9rpbo8/<path>` and settle the 402. How to pay: [payment.md](https://agents.machina.gg/zcj/b99z9s9rpbo8/payment.md).
