Contract-change authorization for AI agents: preflight a change to an API or MCP contract, get a signed decision, and verify the receipt offline. Only a granted change can proceed.
Scores how well AI agents will use your API, 0-100, from its OpenAPI spec. Free and read-only.
Test and debug your AI agent's Web Bot Auth (RFC 9421) signature: is it valid, and what to fix?
Developer checks and Agent Observatory: A2A, MCP and OpenAPI checks with a dated change log.
Remote MCP that evaluates one public HTTPS URL for WebMCP readiness: intent, tools observed, what to add, what never to expose.
Retrieve YouTube transcripts with timestamps, native captions and asynchronous generation when captions are unavailable. Requires a Capslane API key.
AI-Powered Java/Spring Boot code review API with Alipay AI Pay support.
Free platform to test MCP clients without installing anything. Create mock tools with dynamic templates, configurable delays, conditions (if/then), and response sequences. Supports JSON-RPC 2.0 over Streamable HTTP. Built-in text_echo and json_echo tools. Rate-limited tiers: anonymous (5 calls/min, 1 mock tool), registered (10 calls/min, 4 mock tools), premium (60 calls/min, unlimited). Zero setup — no install, no registration required.

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.
Deterministic JSON checks with signed evidence and x402-paid execution
Free tools: x402 endpoint directory + probe, on-chain x402 demand signal, sudoku, API pricing.
Discovery registry for AI agents: 660+ APIs, MCP servers and CLIs, each health-checked every 6 hours with real requests — full initialize + tools/list handshakes for MCP, real calls for APIs — plus response-schema validation that catches responses which parse fine but are missing a required field.
Is this x402/MPP API safe to pay? $0.001 go/no-go preflight, diagnosis and fixes. Free quick check.
Inspect external HTTPS 429/503 retries with server-recorded attempts, Retry-After and arrival times.
Sanctions API docs and request validation, with account-linked synthetic sandbox testing.
Free MCP, API auth, webhook and schema diagnostics with bounded checks and safe quote routing.

Any API, four tools: discover, call with routing and signed receipts, verify, dispute.
What is known to be broken in an MCP server or API operation, with the check that found it.
Point Claude Code, Qwen Code, Cursor, or any MCP client at https://docs.jmeter.ai/api/mcp and your agent answers JMeter questions grounded in this documentation, with a source link for every answer. Free, no API key, no signup.
