Agent Metadata
Known Gotchas
- ⚠ OAuth 2.0 mandatory — no personal access tokens available, requires user interaction
- ⚠ Access tokens expire every 3 hours — frequent refresh token cycles needed
- ⚠ Error codes returned in JSON body with status 200 HTTP — agents must check body, not HTTP status
- ⚠ Rate limits not publicly documented — agents must implement conservative backoff
- ⚠ Domain verification required for OAuth app registration
- ⚠ API uses non-standard action parameter pattern (action=getmeas) rather than RESTful path structure
- ⚠ Data availability depends on device sync — measurements may not appear immediately
