v1.0.0

Live DDG Agent Services catalog over remote MCP: 54 tools for discovering and calling 376 pay-per-call x402 routes (USDC on Base), quoting payment challenges, and checking service status. No account or API key required.

What ddg-services does, in the publisher's words

Remote MCP server for DDG Agent Services: 54 tools over one streamable-HTTP endpoint, backed by 376 live HTTP x402 routes (410 services in the live catalog, 376 HTTP paths plus tool-level services) on USDC. No account, no API key, no human checkout.

So an agent can price, plan, and validate an integration without spending anything. Nothing is charged until the agent itself supplies payment headers. The catalog also carries permanently free routes (price_usd: "0.00": chain status, rules/spec lookups); ddg_list_services flags them.

Protected routes return a structured HTTP 402 with a PAYMENT-REQUIRED header containing accepts[] (scheme, network, asset, amount, payTo). The agent pays on-chain and replays the request with the payment header.

  • Settlement: x402 over USDC: Base mainnet is the default (eip155:8453, USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913); Polygon, Arbitrum, and World Chain are also accepted. ddg_x402_supported_chains returns the current list.
