How this service works
Top-selling x402 bazaar services by unique paying buyers in the last 30 days. Send {"limit":25}, optionally with {"query":"weather"} or {"max_price_usd":0.01}. Per listing: resource URL, host, price, networks, 30-day calls and unique payers, last call time, and description, plus a host leaderboard. Skips listings whose only payment is their own indexing call. From Coinbase discovery metrics, refreshed every 6 hours.
Output
A ranked list of up to 50 x402 bazaar listings, each including the resource URL, host, price, supported networks, 30-day call count, 30-day unique payer count, last call timestamp, and service description. Also includes a host leaderboard summarizing which API providers are most active. Listings with only self-indexing calls are excluded to ensure genuine demand signals.
Example use cases
Niche research before building an x402 service
“Before I build an x402 PDF-to-markdown API, can you check the bazaar demand data for 'pdf' and show me up to 25 listings — I want to know how many unique buyers similar services are getting and what they charge?”
Budget-conscious discovery of popular x402 APIs
“Find me the top 20 x402 bazaar services under $0.005 each, ranked by how many unique people are actually paying for them — I want to invest only in APIs with proven demand.”
Competitive landscape scan for a specific x402 category
“What are the top-selling x402 image services on the bazaar right now? Show me up to 15 results so I can see which hosts are leading and what the going prices are.”

Endpoint
POSThttps://audit.152-53-82-29.sslip.io/v1/bestsellers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real demand signal — actual paying buyers — for x402 bazaar services, rather than just listing counts or crawl rankings. Ideal for market research before building a new x402 API, for competitive analysis within a category, or for discovering which services have proven monetization. Prefer this over generic API directory searches when you specifically want x402/micropayment-native services with validated buyer activity.
Side effects
- Invalid limit value (outside 1-50 range) returns a validation error
- Keyword query with no matching listings returns an empty result set
- max_price_usd too restrictive filters out all results, returning empty list
- Data may be up to 6 hours stale since metrics refresh every 6 hours
- $0.01 USDC payment required per call; insufficient funds or payment failure blocks access
