# Build with your agent

Connect your coding assistant to the docs or start with a task prompt.

## Connect the documentation MCP

Add this Streamable HTTP URL in a compatible MCP client. The server provides public documentation and API schemas; it does not require a merchant API key.

```text
https://api.coinssend.com/v1/docs/mcp
```

[Read the client setup guide](/payments/agents/mcp/)

## Choose a task

Preview a prompt, copy it into your own coding agent, or download a focused documentation bundle. Prompts and the detailed API contract are currently in English.

- [Checkout integration prompt](/payments/agents/prompts/#full-checkout-integration-prompt)
- [Webhook receiver prompt](/payments/agents/prompts/#webhook-receiver-prompt)
- [Integration review prompt](/payments/agents/prompts/)

## Use the current contract

Use OpenAPI for fields and schemas, the guides for workflow, and signature test vectors for interoperability. Keep credentials in your own server environment.
