Capabilities

Tools 4

check_agent_readiness

Free check of whether AI agents can use a business's website: can they get in, understand it, act on it (API, MCP) and trust it. Returns a 0–100 score, a verdict, and each check with what was found and how to fix it.

Discovered
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 the catalog last saw it active, how many of the last 30 days its payment address was paid, on-chain USDC payments and distinct paying wallets on Base over 30 days (with a one-wallet wash warning), a live check that it really answers 402 and asks to be paid at its listed address (x402 version, CAIP-2 networks), 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.

Discovered
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.

Discovered
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.
