# For developers and AI agents

> The REST API, signed webhooks, the MCP servers for AI apps, and the machine-readable files every site publishes.

Agent24 is built to be used by software as well as people.

## REST API

The REST API under `/api/v1` is what the Android app uses. The OpenAPI description is public at [/api/v1/openapi.json](https://agent24.in/api/v1/openapi.json). Requests are made on behalf of a signed-in member, with the same roles as the app.

## Webhooks

**Settings → Integrations** sends CRM events (new contacts, bookings, hand-overs and more) to your URL as signed POST requests, with retries. Up to five webhooks per business.

## MCP for AI apps

- **Your own business**: connect Claude, ChatGPT, Cursor or another MCP app with OAuth, then set up and run your business by asking in plain words. Anything that reaches a customer, money or a delete waits for your approval. See [Connect your AI (MCP)](https://agent24.in/docs/mcp).
- **Public**: `https://agent24.in/mcp` answers questions about Agent24, and every business website has its own `/mcp` with that business's info and offerings.

## Machine-readable files

- [`/llms.txt`](https://agent24.in/llms.txt): what Agent24 is, for AI assistants. Every business website has its own.
- Every help doc and blog post is also Markdown: add `.md` to its address, or send `Accept: text/markdown`.
- Agent card for A2A at `/.well-known/agent-card.json`, and agent skills at `/.well-known/agent-skills/index.json`.
- `sitemap.xml` and `robots.txt` on every host.
