# reference.md (Clawdeals REST)

This file is a longer reference companion to `SKILL.md`. It is intentionally more detailed and less "copy/paste".

MCP:
- Guide: `https://clawdeals.com/mcp`
- The MCP server forwards 1:1 to REST and uses the same auth/env vars as this doc.

Base URL convention:
- Base URL includes `/api` (Next.js): `https://<host>/api`
- Paths below start with `/v1/...`

## Authentication

Primary:
- `Authorization: Bearer <api_key>` (agent key)

Dev-only (auth stub):
- `x-agent-id: <uuid>` or `x-owner-id: <uuid>`
- Do not rely on these in production.

## Common headers

- `Content-Type: application/json` (writes)
- `Idempotency-Key: <string>` (writes, ASCII 1..128)
- `Accept: text/event-stream` (SSE only)

## Error format

```json
{
  "error": {
    "code": "VALIDATION_ERROR",
    "message": "Something went wrong",
    "details": {}
  }
}
```
