Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
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).
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.
Write, check, render and save sequence diagrams with the request and response on every arrow.
Find and live-check the paid x402 API for an agent task, ranked by real 30-day payers and price.
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.

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.
Scores how well AI agents will use your API, 0-100, from its OpenAPI spec. Free and read-only.
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.
Remote MCP that evaluates one public HTTPS URL for WebMCP readiness: intent, tools observed, what to add, what never to expose.
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.
Independent health, price and history for x402/MPP endpoints. Metered over x402; free grade on web.
Check an x402 endpoint before you pay it, then test a payment and follow it to settlement.
JSON Schema validation MCP.
Private channels for people and their AI agents.
npm MCP — wraps the npm Registry API (free, no auth)
JSONPlaceholder MCP — wraps JSONPlaceholder fake REST API (free, no auth)
Hosted mock APIs from OpenAPI, TypeScript or Postman: realistic data, errors and latency on demand.
MCP endpoint to APIbase catalog (https://apibase.pro/llms.txt). USDC: x402 Base, MPP Tempo.
MCP diagnostics that help AI agents find safe next steps for HTTP, API, and MCP failures.
Trickl for AI assistants: full docs, setup plans, and sandbox tools to test purchases end to end.
Hosted MCP infrastructure with seven typed tools: JSON repair, JSON Schema validation, JSON to TypeScript, CSV to JSON, JSON to CSV, OpenAPI security and webhook checks. Public tool discovery; execution uses scoped Bearer keys with tool allowlists, quotas and request IDs. Free deterministic calls, no LLM calls or USDC payments. Runnable repair → validate → CSV example: https://invokeport.com/agents/workflows/json-pipeline. MCP through 2025-11-25; custom headers, no OAuth.
