# Coverage Cat OpenAPI and Discovery Docs

## Coverage Cat API discovery URLs

- `/api/agent`: primary discovery JSON
- `/api/agent.md`: markdown mirror of the discovery document
- `/api/agent/openapi.yaml`: public OpenAPI YAML
- `/api/agent/openapi.yaml.md`: markdown mirror of the OpenAPI download path
- `/openapi.json`: public OpenAPI JSON
- `/api/openapi.yaml`: predictable YAML alias

## What the Coverage Cat contract covers

- Delegated umbrella purchase workflow
- Direct homeowner handoff plus delegated homeowners quoting
- Read-only calculators and the homeowners agent finder
- Auth endpoints for operator-key issuance and rotation
- Sandbox and rehearsal semantics

## Related Coverage Cat metadata

- `/.well-known/api-catalog`
- `/.well-known/agent-skills/index.json`
- `/.well-known/ai-catalog.json`
- `/api/llms.txt`

## Preferred order

1. Start with `/api/agent`.
2. Fetch `/api/agent/openapi.yaml` or `/openapi.json`.
3. Read the relevant runtime markdown skill.
4. Use `/developers/auth` and `/developers/sandbox` before you attempt live delegated traffic.
