How this service works
x402 API market data report. Market report for sellers and builders: for a category (need, e.g. token safety) or the whole x402 index, resource and seller-host counts, hosts with 3+ payers, listed price quartiles, the price where buyers are (payer-weighted median), 30-day calls, estimated 30-day revenue (calls x price, an upper bound), top sellers and the resources with most payers. Use it to price a new endpoint or test a niche for paying demand. limit 1-25 (default 10).
Output
Returns a JSON object containing: ranked top resources by payer count (with price, call volume, relevance score, description, supported networks), aggregated seller stats (total hosts, price distribution, estimated 30-day revenue), index freshness metadata, search terms parsed, active filters, a confidence rating, and a disclaimer. Each resource entry includes host, service name, method, price in USD, 30-day calls and payers, repeat-buyer flag, and last-called timestamp.
Example use cases
Finding crypto-payable web search APIs
“Can you check the YourAITools market index for any APIs that do web search and accept crypto payments on Base — show me the top 10 ranked by payer count?”
Discovering DeFi data tools on Solana
“I need a DeFi analytics or funding rate API I can pay with crypto on Solana — can you search the YourAITools marketplace for something like 'hyperliquid funding rates' and show me the top sellers?”
Sourcing a PDF-to-text microservice for an agent
“Look up 'pdf to text' in the YourAITools ToolPick market index and give me the best-ranked services I can pay in USDC, up to 5 results on any network.”
Technical details
Endpoint
GEThttps://api.youraitools.co/toolpick/v1/market?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to discover x402-compatible (crypto-payable) APIs or tools for a specific task, especially when the agent wants to compare sellers by price, payer activity, or network (Base, Solana, etc.). Prefer this over generic API marketplaces when USDC/crypto micropayment compatibility is a hard requirement, or when the agent needs live market statistics like 30-day call volumes, payer counts, and price distributions across the x402 ecosystem.

- sources_failed array populated when one or more index sources are unreachable
- No results returned when 'need' query matches no indexed tools
