Superstables is an open-source, non-custodial platform that enables AI agents to make payments across multiple rails, chains, and stablecoins through a single API call. It provides a live, independently probed index of payable services and on-chain yield, accessible via a public JSON API and MCP server without requiring keys or accounts.

A practical workflow
- Query the index via GET /api/v1/services with filters for rail, chain, asset, and live status.
- Submit a service endpoint for listing via POST /api/v1/submit, which probes the endpoint before publishing.
- Use the MCP server with native agent tools like find_services, get_service, and get_stats for integration.
