Ultralytics Platform

REST API at https://platform.ultralytics.com, auth Authorization: Bearer ul_.... Interactive spec: GET /openapi.json (needs the bearer header).

The auth shape and the four gotchas below were run against the live API on 2026-08-04. Endpoint shapes not covered by those runs come from /openapi.json and are marked unverified in references/.

Get the key first

export ULTRALYTICS_API_KEY=ul_... # Settings > API Keys on platform.ultralytics.com

The ultralytics package reads ULTRALYTICS_API_KEY env first, then api_key in settings.json (yolo settings api_key=ul_...). Check both before assuming the key is missing.
