> Canonical human- and machine-readable directory for the CCA public data-service fleet.

The catalog is generated from one version-controlled manifest. Service metadata is descriptive; verify each service's documentation and status before production use. The September 2026 fleet audit found 19 live OpenAPI documents covering 692 operations, with substantial operationId, response-schema, and example gaps. Agent-readiness labels are therefore evidence-based and intentionally conservative.

## Discovery

- [Catalog API](https://services.datasourceapi.com/api/v1/services): Filterable JSON metadata for every service
- [RFC 9727 API catalog](https://services.datasourceapi.com/.well-known/api-catalog): Normative API discovery linkset
- [Catalog OpenAPI](https://services.datasourceapi.com/openapi.json): OpenAPI 3.1 contract for this catalog
- [APIs.json](https://services.datasourceapi.com/apis.json): APIs.json 0.23-compatible supplementary catalog
- [Catalog status](https://services.datasourceapi.com/api/v1/status): Health of this directory
- [MCP endpoint](https://services.datasourceapi.com/mcp): Stateless, read-only metadata tools over Streamable HTTP
- [Fleet standards](https://services.datasourceapi.com/standards): Versioned UI, API, data, safety, and operations requirements
- [Standards API](https://services.datasourceapi.com/api/v1/standards): Machine-readable normative rules and reusable validation artifacts

## Workflows

1. Search the catalog API by kind, audience, lifecycle, status, or capability.
2. Read a service's Markdown page at `/services/{id}.md`.
3. Follow its OpenAPI and documentation links; do not infer unsupported operations.
4. Use the MCP tools `search_services`, `describe_service`, and `list_service_operations` for progressive metadata discovery.
