## How to call
- **Endpoint:** `POST https://api.reefapi.com/kanabell/v1/<action>` with a JSON body.
- **Auth:** header `x-api-key: <YOUR_REEFAPI_KEY>` — create one free (1,000 credits, no card): https://reefapi.com/signup
- **Response (every call):** `{ ok: boolean, data: ..., meta: { record_count, credits, ... }, error: { code, message } }` — branch on `ok`. Failed calls are free.
- **One key + one shared credit pool** across every ReefAPI API. Per-call credits are listed on each endpoint below.
- **Use it from an AI agent (MCP):** connect `https://api.reefapi.com/mcp` (remote streamable-http). Clients that add connectors by URL, such as ChatGPT and the Claude app, connect with OAuth 2.1 (the user pastes their key once on a ReefAPI page; discovery at `/.well-known/oauth-protected-resource/mcp`). Config files send the key as `Authorization: Bearer <key>`. `?key=<key>` in the URL also works as a last-resort fallback.
