What uses the spec

The OpenAPI spec is the single source of truth for all ListBee clients and tools:

  • MCP server — tools are derived from the spec via fastapi-mcp
  • SDKs — type definitions and method signatures derived from the spec
  • API reference — auto-generated by Fern from the spec
  • Postman / Insomnia — import the JSON URL directly
  • AI agents — feed the spec URL or llms.txt to any LLM for full API context

llms.txt

The llms.txt file is a condensed, plain-text summary of the API designed for LLM consumption. It includes endpoint descriptions, parameter types, and example payloads in a format optimized for context windows.

Next steps

  • API reference — browse the full endpoint documentation.
  • MCP server — connect the spec-powered MCP tools to your AI assistant.
