# Unif API Docs

> Agent-first documentation for UnifAPI Skills, MCP OAuth, and live public-data APIs.

Use these docs when an agent or developer needs to understand UnifAPI's public-data layer. Start with Skills and MCP for agent workflows; use the API reference when productizing a workflow over HTTP.

Important boundaries:

- UnifAPI serves public data, not user-authorized private SaaS data.
- MCP OAuth authorizes a UnifAPI workspace and credit balance.
- Skills reuse the user's existing agent product plan; UnifAPI bills public-data operations with $0.001 credits and OpenAPI-published operation minimums.

Primary entry points:

- Skills catalog: https://unifapi.com/skills
- KOL Pricing Skill: https://unifapi.com/skills/kol-pricing
- MCP server: https://mcp.unifapi.com
- Install surfaces: Claude custom connectors, ChatGPT approved apps or developer mode custom MCP apps, OpenClaw/Hermes MCP config, Codex and Claude Code MCP CLI setup, Cursor or VS Code MCP server galleries, and manual MCP connector setup.
