UCM Skill — API Marketplace for AI Agents

An Agent Skills compatible skill that gives any AI agent instant access to 100 services with 217 endpoints — web search, image generation, code execution, text-to-speech, translation, email, stock data, weather, and much more. 87 services are completely free.

Works on: Claude Code, OpenAI Codex CLI, GitHub Copilot, Cursor, VS Code, Gemini CLI, Goose, Roo Code, Windsurf, Amp, and any platform supporting the Agent Skills standard.

What It Does

When this skill is installed, your agent can:

1. Discover services — Search by natural language ("I need to convert a PDF to text")
2. Call services — One HTTP call to purchase and execute any service
3. Get $1.00 free credits — Register automatically, enough for 100+ API calls

No SDK, no MCP server, no running processes — just HTTP calls.

Quick Test

After installing, ask your agent:

"Search the web for the latest AI news using UCM"

The agent should automatically:

1. Check for existing credentials at ~/.config/ucm/credentials.json
2. Register if needed (free, $1.00 credits), save credentials for next session
3. Call ucm/web-search via POST /v1/call
4. Return the search results
