APIs

These endpoints exist and answer today, unauthenticated while in beta. Key authentication and per-tier rate limits are planned before general availability.

Point forecast live today

GET /api/forecast?lat=&lon=&model=&params= returns hourly values for any cached field at one location.

Bulk forecast live today

POST /api/forecast/bulk accepts up to 1,000 points per request, with splines built once per grid.

Sounding live today

GET /api/sounding/{model}/{run}?lat=&lon=&fhr= returns the full vertical profile at a point.

Member plume live today

GET /api/plume/gefs/{run}/t2m?lat=&lon= returns all 31 GEFS members at a point for every cached hour.

Planned pricing in USD and subject to change before launch. The whole stack is self-hostable: model data comes from NOAA open data and serves from one machine.
