classifier.dev docs

List every classifier.dev document available over this server — the API reference, the benchmark, the agent skill, the CLI, pricing, privacy, terms and the MCP setup guide — with an id, a title, its section headings and its size. Call this first, then read_doc for the one you need.

    }

Return one document in full, or just one of its sections. ids: api, developers, mcp-setup, benchmark, skill, llms, pricing, auth, agents, privacy, terms, about, contact. Use section to fetch a single heading (case-insensitive prefix match) when the whole document is more than you need.

    "id": {
      "type": "string",
      "enum": [
        "api",

      "description": "Which document."
    },

Full-text search across every classifier.dev document. Returns the paragraphs that contain all of your query's words, with the document and section each came from. Use it for a specific question — rate limits, how confidence is calibrated, how to connect from Claude or ChatGPT — instead of reading whole documents.

{
  "type": "object",
  "properties": {
    "query": {
      "type": "string",
      "minLength": 2,
      "maxLength": 200,
      "description": "Words to look for; all must appear in a paragraph."
    },
    "limit": {
      "type": "integer",
      "minimum": 1,
      "maximum": 50,
      "default": 10
    }
  },
  "required": [
    "query"
  ],
  "additionalProperties": false
}

Return a copy-pasteable example of calling classifier.dev from a given client: curl, javascript (fetch), python (requests), the classify CLI, or an MCP tools/call payload. Use this when you are about to write integration code and want the exact request shape rather than reading the whole reference.

    },
    "multi_label": {
      "type": "boolean",
