Windfield — AI / automated-use policy
https://windfield.summitflux.com

Free to use. Free to cite.
=============================
Windfield is a free, open, no-login web application and public JSON API,
built by SummitFlux LLC on the USFS WindNinja 4.0 terrain wind model. You
may read, summarize, cite, quote, link to, and build on this site and its
API output — for training, retrieval, agent tool-use, research, journalism,
or any other purpose — without asking permission.

Attribution (requested, not required)
=============================
If you cite or redistribute results, please credit:
  "Windfield by SummitFlux, powered by USFS WindNinja"
and, where convenient, link https://windfield.summitflux.com and
https://windfield.summitflux.com/credits.html (full list of underlying
data sources: WindNinja, AWS Terrarium/Mapzen elevation, OpenStreetMap,
OpenTopoMap, Esri, Open-Meteo, NOAA NWS/NOMADS, OSM Nominatim, Leaflet).

Using the API
=============================
Base URL: https://windfield.summitflux.com/api/v1
JSON. No auth. No API key. CORS is open.
Full reference: https://windfield.summitflux.com/help.html#api
Machine-readable summaries: /agents.txt and /agents.xml
Capabilities (live limits): https://windfield.summitflux.com/api/v1/capabilities

Fair use / limits
=============================
This is a small, free service with modest server capacity. Please keep
automated request rates light (a few requests per second at most) and
respect the `retry_after` value on a 429 response. Current budgets,
reported live by GET /api/v1/capabilities and mirrored here:
  - domain up to ~400 km on a side (soft/informational)
  - up to 1,500,000 mesh cells per run
  - up to 15 minutes (900 s) of run time per run
  - up to 2 jobs running at once, 20 queued, 2 in flight per IP/visitor
  - job results expire roughly 5 minutes after the last time anyone
    checked on them (status/files/log fetch, or a keepalive call) —
    do not assume a job id or its files are durable; re-POST
    GET /api/v1/jobs/{id}/recipe to recreate a run instead
There is no paid tier and no way to raise these limits; they apply equally
to everyone, including SummitFlux's own front end.

No login, no tracking wall
=============================
There is no account system and nothing here is gated behind login or
payment. See https://summitflux.com/privacy-policy and
https://summitflux.com/terms for the governing privacy policy and terms.
