## Standards and protocols

| [OpenAPI Specification](https://www.openapis.org/) | The API description standard used in adjacent integration material |
| [OpenID Connect](https://openid.net/connect/) | The OIDC standard used for SSO and SSO-driven role mapping |
| [SAML 2.0](https://docs.oasis-open.org/security/saml/v2.0/) | The federated authentication standard, for background only; Agent Router supports OIDC and not SAML |
| [OpenTelemetry](https://opentelemetry.io/) | The observability standard used for trace and metric export |
| [OTLP Specification](https://opentelemetry.io/docs/specs/otlp/) | The wire protocol for OpenTelemetry data |
| [Prometheus](https://prometheus.io/) | The metrics format exposed on the gateway's scrape endpoint |
| [Server-Sent Events](https://html.spec.whatwg.org/multipage/server-sent-events.html) | The streaming format used by all three supported API surfaces |
| [Model Context Protocol](https://modelcontextprotocol.io/) | The MCP standard for exposing tools, data sources, and context to AI clients |

## Provider documentation

For provider-side concerns (model pricing, rate-limit tiers, API quirks not handled by the gateway's translation layer, and account management), the canonical source is each provider's own documentation.
