How this service works
Find a paid API for any task: one search over every x402 API on Coinbase Bazaar, Circle, Fuci and CRA, ranked by distinct paying wallets in 30 days, with price, chains, repeat-buyer rate and a live 402 check. Find the paid API that does what you need, ranked by paying wallets: one search over every x402 API we can see (Coinbase Bazaar, Circle's catalogue, Fuci Market, CRA, sellers listed on APEX Market).
Output
A ranked list of x402 API listings matching the query, each with price per call, supported chains, number of distinct paying wallets in the last 30 days, repeat-buyer rate, and a live HTTP 402 check result indicating current availability.
Example use cases
Finding a token price feed API
“Find me the best paid x402 API for getting real-time token prices — I want something on Base chain, under $0.01 a call, ranked by how many people are actually paying for it.”
Discovering web scraping APIs on x402
“I need a paid API that can scrape web pages — can you search the x402 marketplaces and show me the top options by paying wallets, with their prices and whether they're live right now?”
Comparing sentiment analysis APIs by repeat buyers
“Search all x402 API markets for sentiment analysis APIs, and rank them by repeat-buyer rate so I can tell which ones people actually keep coming back to use.”
Technical details
Endpoint
GEThttps://apexfaucet.xyz/api/x402/market-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover and compare paid x402-protocol APIs across multiple marketplaces (Coinbase Bazaar, Circle, Fuci, CRA) in a single call, especially when you want real usage signals like paying wallet counts and repeat-buyer rates rather than just listings. Prefer this over manually querying each marketplace or using general API directories when you specifically need x402-compatible, crypto-payable APIs.

- Query string exceeds 120 characters is rejected
- No matching APIs found returns empty result set
