# Introduction

> Programmatic access to the Anyreach platform over a REST API.

The Anyreach API is organized around REST. It has predictable, resource-oriented URLs, accepts JSON request bodies, returns JSON responses, and uses standard HTTP verbs and status codes.

## Base URL

All endpoints are relative to:

```
https://api.anyreach.ai
```

Endpoints are grouped by service and each group has a path prefix:

| Prefix            | Service                                                                           |
| ----------------- | --------------------------------------------------------------------------------- |
| `/core`           | Agents, conversations, phone numbers, trunks, web widgets, email, inbound routing |
| `/knowledge-base` | Knowledge bases (datasets), sources, retrieval                                    |
| `/workflow`       | Workflows, executions, triggers                                                   |
| `/campaign`       | Outbound campaigns, contacts, configurations                                      |
| `/mcp`            | Model Context Protocol server                                                     |

## Conventions

* **Requests** — send JSON with a `Content-Type: application/json` header. List endpoints take filters as query parameters and paginate with a cursor.
* **Responses** — always JSON. Timestamps are ISO 8601 (UTC). IDs are opaque strings; don't parse them.
* **Authentication** — every request needs a bearer credential (`ak_` or `pat_`). See [Authentication](/api-reference/authentication).
* **Errors** — non-2xx responses return a JSON `detail` message. See [Errors](/api-reference/errors).
