Tools
| Tool | Description | Behaviour |
|---|---|---|
| check_payability | Free. Check whether an x402 endpoint or MCP tool is real, payable and active BEFORE you pay it. Pass a URL; get a 0–100 payability score, the listed price and networks, when it was last active (for paid listings, the last settled payment), and flags for catalog-flooding or outlier pricing. Scored from the public PayAI x402 Bazaar + MCP Registry index — listings are third-party data, not endorsed. Returns a 0–100 score, a verdict (payable / mixed / unverified), the listed price, networks and last-active date, plain-language signals, and provider flooding / price-outlier warnings. | Not declared |
| find_tools | Free. Free search across public agent-tool catalogs — paid x402 APIs and MCP tools (PayAI's x402 Bazaar) and MCP servers (the official MCP Registry). Describe what you need in plain words; get matching tools with price, payment networks and how to call them. Returns up to 10 matches with kind (x402-http, x402-mcp, mcp-remote, mcp-package), URL, price per call in USD when listed, payment networks, and a one-line howToUse. `matched: false` means nothing covered your request well. | Not declared |
| report_unmet_need | Free. Nothing fits? Say what you needed (free, no personal information): the report_unmet_need MCP tool, or POST https://subpay.ai/api/v1/find/unmet. It decides what gets built next. | Not declared |
