GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
Signed declarations of HTTP API exchanges for agent handoffs. Free preparation and verification; receipt issuance costs 0.002 USDC via x402 on Base. Start and connect: https://datoka.dev/api. Signatures attest declared data, not independent truth.
API documentation drifts away from the running service, so consumers integrate against a contract nobody keeps. Routebase keeps API design, testing, mocking and documentation on one living source of truth, and this MCP server exposes that workspace to AI agents. Agents can design endpoints, write and run test suites, manage mock servers and publish documentation, always under the permissions of the connected Routebase account.
Verified, reproduced behavior of public HTTP APIs: spec gaps, errors, pagination, auth.
Free tools: x402 endpoint directory + probe, on-chain x402 demand signal, sudoku, API pricing.
Independent checks of paid x402 data sellers and of AI-agent access to shopping and travel sites
Audits a sample of HTTP request URLs against explicit, documented cache-key standardization rules...
Experimental MCP server for current empirical verification of explicit public HTTPS endpoint claims.
