Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
Read-only MCP server for querying OkkMax measurements of AI API relay services, including model availability, observed prices, 24-hour uptime, latency, and model- and group-level purity evidence. No sign-in or API key is required.
SqueezeOS MCP for x402-paid USDC APIs on Base. Flagship read settle-proven 2026-11-02 (SELF-PROOF).
See which AI models fall for traps in everyday jobs, and check or scan any MCP server, skill or package before your agent installs it. No sign-in; read-only; returns structured data.
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.
Audits any remote agent or MCP URL for JSON-RPC compliance, latency SLA, OpenAPI schema, and HTTP.
Write, check, render and save sequence diagrams with the request and response on every arrow.
Independent static checks for supported tag and alarm CSV import formats; no HMI or PLC access.
Audits any live MCP server URL or GitHub repo on Glama's 6-dimension TDQS rubric and compiles drop
Audit any domain or agent for A2A, MCP, x402, MPP, ERC-8004, and Poppy readiness.

Traffic Parrot simulates APIs and messaging. Request or withdraw a trial, read docs, send feedback.
Free *.pntr.dev dev subdomains — register subdomains, manage DNS and wildcard records, receive email on disposable inboxes, and capture HTTP requests for webhook debugging. OAuth sign-in; free tier.
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.
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.
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.
Independent health, price and history for x402/MPP endpoints. Metered over x402; free grade on web.
Live road conditions for the agent web: check a site or API before acting, report after.
Web/PDF extraction and API comparison. x402 payments or prepaid comparison credit. Free discovery.
Hosted mock APIs from OpenAPI, TypeScript or Postman: realistic data, errors and latency on demand.
Hands-on test results for 560+ remote MCP connectors: does it work, how to sign in, what breaks.
Find any agent service, and check it before you pay for it or rely on it.
Free tools: x402 endpoint directory + probe, on-chain x402 demand signal, sudoku, API pricing.
What is known to be broken in an MCP server or API operation, with the check that found it.
Free agent tests (no account or payment); paid ping.
Paid OpenAPI audit and API change detection for agents. $0.10 USDC per analysis via x402 on Base.
Test FIX from Claude, ChatGPT, or Cursor: free sandbox FIX sessions or your own FIXSIM instances.
Remote MCP for 1,500+ APIs. Vault-managed credentials; OAuth or API key. Search, load, and execute.
Debug webhooks from your AI agent: inspect and replay captured webhooks on localhost.
40+ developer tools from Context7, Code Runner, Python Execute, NPM Sentinel, PlantUML, and Microsoft Learn. Docs lookup, code execution, security scanning. Starts at $0.01/call. Get your API key at app.xpay.sh or xpay.tools
