A webhook inbox for agents: one call returns a live URL. Mock, verify, inspect and replay.
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.
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.
Find the best pay-per-call API for any task: price, uptime and real usage across 19,000+ APIs.
SqueezeOS MCP for x402-paid USDC APIs on Base. Flagship read settle-proven 2026-11-02 (SELF-PROOF).
Uptime checks, status pages, incidents, and maintenance for websites, APIs, DNS, and TCP.
Audits any remote agent or MCP URL for JSON-RPC compliance, latency SLA, OpenAPI schema, and HTTP.
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.
Simceptor is an AI-native Mock API simulation platform with a built-in MCP server. It enables AI agents to create, inspect, update, and test dynamic mock APIs, conditional response rules, stateful session simulations, and network latency directly from context.
Independent static checks for supported tag and alarm CSV import formats; no HMI or PLC access.
Find and live-check the paid x402 API for an agent task, ranked by real 30-day payers and price.
Audit any domain or agent for A2A, MCP, x402, MPP, ERC-8004, and Poppy readiness.
Grade MCP tool definitions for agent-readiness: score, A-F grade, fixes, est. token cost.
Deterministic release-compatibility preflight for OPC UA NodeSet2 XML.
Audits any URL for HTTP 402 x402 V2 compliance, PAYMENT-REQUIRED headers, Bazaar schema, and MCP.
Parallel-burst abuse testing for agent APIs with replayable evidence packs.
Pair-level MCP+A2A conformance verdicts for the exact pair you delegate across.
Test and debug your AI agent's Web Bot Auth (RFC 9421) signature: is it valid, and what to fix?
Is this x402/MPP API safe to pay? $0.001 preflight, fixes, a $0.25 test purchase. Free quick check.
Remote MCP that evaluates one public HTTPS URL for WebMCP readiness: intent, tools observed, what to add, what never to expose.
Registry Rot Watch: liveness + successor-contract verdicts for MCP endpoints.
Annotation-survival conformance for MCP tools. Receipt $0.01, check $4.99, plans $9.99/$19.99.
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.
AI-callable tools for API mocking, testing, monitoring, security, and automation.
Check an x402 endpoint before you pay it, then test a payment and follow it to settlement.
Private channels for people and their AI agents.
Live road conditions for the agent web: check a site or API before acting, report after.
