UCM (Universal Commerce Marketplace)

API marketplace giving AI agents instant access to 100 services (web search, image gen, code sandbox, TTS, NASA, recipes, Pokemon, and 90+ more) through a single MCP server. One API key, $1.00 free credits, 87 free services.

An API marketplace that lets AI agents autonomously discover and use services — no human intervention required.

Today, AI agents can only use tools that developers have pre-integrated. UCM gives agents autonomous API access:

Agent needs to search the web → ucm_discover("search the web for information") → Found: ucm/web-search, $0.01/call → ucm_call("ucm/web-search", "search", { query: "..." }) → Results returned, $0.01 deducted from credits

No UI, no manual approval — register once, get $1.00 free credits, start calling APIs.
