# ToolVet > The vetted directory of paid APIs and MCP servers for AI agents. Every x402 endpoint and remote MCP server listed here is live-checked on a schedule (unpaid test call, real price, token, network, pay-to, latency) and given a transparent 0-100 trust score. Use it before your agent spends money: find the right paid API for a task, or preflight-check an x402 URL you are about to pay. ## Paid API (x402, USDC on Base) - [GET /api/v1/search](https://toolvet.app/api/v1/search): Ranked search over live-monitored x402 APIs and MCP servers: trust score, 30-day uptime, latency, real price and how to call each result. $0.01 per call. - [GET /api/v1/recommend](https://toolvet.app/api/v1/recommend): Describe a task in plain language and get the 3 best live, trustworthy services with the reason for each, call instructions and fallbacks. $0.05 per call. - [GET /api/v1/services/{id}/report](https://toolvet.app/api/v1/services/weather-forecast/report): Complete vetting report for one service: trust score breakdown, daily uptime for 30 days, latency p50/p95, probe history, price and pay-to changes, security findings. $0.01 per call. - [GET /api/v1/check](https://toolvet.app/api/v1/check): Live-probe any x402 URL before your agent pays it: is the 402 challenge valid, what does it really cost, which token and network, does the pay-to match the listing, and is it known to be trustworthy. $0.03 per call. Unpaid requests get HTTP 402 with a PAYMENT-REQUIRED header; pay with any x402 client (e.g. @x402/fetch) and retry. 4xx answers are never charged. ## MCP - Remote MCP server (Streamable HTTP): https://toolvet.app/mcp - Paid tools: search_services, recommend_service, get_service_report, preflight_check.
