# Ouro Agents

> Ouro Agents (by Oroboros Design, Cologne, Germany) helps Web3, AI and tech companies get paid by AI agents and put agents to work: custom AI agents, launch sites, x402 pay-per-request payments for APIs, agent discovery (llms.txt, agent cards, OpenAPI, x402 Bazaar, MCP registries) and smart-contract pre-audits. Fixed prices in EUR, business customers only. No custody, no investment advice.

## Free tool

- MCP server (streamable HTTP, no auth): https://ouro.oroboros-design.com/mcp with one tool, `x402_check` (arguments: url, method). Registry entry: com.oroboros-design.ouro/x402-check; metadata at https://ouro.oroboros-design.com/server.json
