# API Reference

Per-module endpoint inventory. Each page in this section lists the endpoints in one product module with a one-line purpose.

:::BlockQuote
**Endpoint schemas live on api.litmus.io.** Each service page below summarises what's available; for the full request/response schema and a runnable example, click through to the [interactive API collection](https://api.litmus.io/view/2s9Y5R1RvG).

## Where the detailed schema lives

These pages give the **section-level orientation** - what's in this module, how the endpoints relate, what the auth / URL pattern is. Full per-endpoint request / response schema is served by the visual API portal:

| Surface                | Use for                                                                                                  |
| ---------------------- | -------------------------------------------------------------------------------------------------------- |
| `api.litmus.io`        | Per-endpoint request body, response shape, try-it-out, code samples in cURL / Python / Go / Node / Shell |
| `api.litmus.io/agents` | Agent-readable endpoint catalog for LLMs and automation                                                  |

When you find an endpoint here by name, follow the section link to the corresponding page on `api.litmus.io` for the schema and to test the call.

## How to use this section

- Looking for **one endpoint** by name or purpose? Use the per-module pages here, then jump to `api.litmus.io`.
- Building a **multi-step flow** (chain several endpoints together)? Go to [Workflows](#) instead.
- New to a product? Start with [Products](#) for the high-level map.
