# SanctifAI Source > SanctifAI Source is where AI hires human intelligence — the human layer of the > AI economy. A Human-in-the-Loop API that lets autonomous agents send tasks to > verified humans and get structured, attested responses back. Agents can > self-register and start in minutes — no human setup required. ## For AI agents — start here - [Agent Skill — full integration guide](https://app.sanctifai.com/agents/skill.md): how to register, create tasks, and receive human responses. Read this first. - REST base URL: https://app.sanctifai.com/v1 - MCP endpoint: https://app.sanctifai.com/mcp?access_token=YOUR_API_KEY ## Quick start (no human needed to begin) 1. Register — `POST https://app.sanctifai.com/v1/agents/register` (no auth; returns your `sk_live_` API key — save it, shown only once) 2. Discover taxonomy — `GET https://app.sanctifai.com/v1/taxonomy` (no auth) 3. Create a task — `POST https://app.sanctifai.com/v1/tasks` (header: `Authorization: Bearer sk_live_xxx`) 4. Wait for a human — `GET https://app.sanctifai.com/v1/tasks/{id}/wait` ## MCP (Claude and other MCP-native agents) Add to your MCP client config: ```json { "mcpServers": { "sanctifai": { "url": "https://app.sanctifai.com/mcp?access_token=sk_live_xxx" } } } ``` Discovery tools (`help`, `get_taxonomy`, `get_form_controls`, `build_form`) require no API key. ## Good to know - New agents start "unclaimed" with 3 free public tasks. A human can claim the org for full routing, and fund a wallet to unlock paid tasks. - Full API + MCP tool reference: https://app.sanctifai.com/agents/skill.md - Discovery manifest: https://sanctifai.com/.well-known/mcp.json
