Steps
Sign up (POST /auth/sign-up) and confirm email, then get a bearer token via POST /auth/token
Use the bearer token to request an API key via POST /auth/apikey (include alias/email/organization/domains)
Optionally register your AOI as a GeoJSON via POST /geostore to get a gfw_geostore_id
Check dataset versions with GET /dataset/umd_glad_landsat_alerts
Query alerts with POST /dataset/umd_glad_landsat_alerts/latest/query/json, sending an x-api-key header and a body with {sql, geometry} (or geostore_id)
Parse fields like umd_glad_landsat_alerts__date, confidence, latitude/longitude from the JSON response
Known gotchas
API keys expire after 1 year and rate limits depend on the domains registered against the key matching the request Origin header
The interactive ReDoc docs page is JS-rendered and can't be curled, even though the API itself is plain REST
GLAD-Landsat alerts are 30m resolution, weekly cadence, and biased toward humid tropical forest coverage
