How this service works
Data about the x402 market: the CDP Bazaar's listings, sellers, prices and categories, new listings and price changes from snapshots every 6 hours, uptime we measure for every paid listing, and x402 spending of any wallet and revenue of any seller on Base.
Output
A JSON array of origin objects each containing: the origin domain URL, total APIs listed, maximum payers in the last 30 days for the best API, total calls in the last 30 days, and median price in USD across all APIs on that origin.
Example use cases
Discovering dominant x402 API providers
“Who are the top 20 origins in the x402 marketplace sorted by most payers? I want to see how many APIs each domain lists and what their median price is.”
Finding highest-volume API seller domains
“Which x402 seller domains had the most API calls in the last 30 days? Show me the top 15 sorted by call volume.”
Benchmarking x402 marketplace breadth by origin
“List the x402 origins that offer the most APIs — give me the top 50 sorted by number of APIs listed, with their payer counts and median prices.”
Technical details
Endpoint
GEThttps://data.kagurazaka.dev/v1/market/origins?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a domain-level aggregated view of the x402 API marketplace — comparing sellers by volume, popularity, or catalog size. Prefer this over per-API endpoints when the question is about which provider or origin domain to trust or explore, rather than which specific API to call.
Side effects
- Invalid sort value returns error — must be one of 'apis', 'payers', 'calls'
- Limit outside 1-50 range may return validation error or be clamped
- Payment not included or invalid results in 402 Payment Required
- Empty results array if no x402 origins are indexed yet
- Stale data if market indexer has not updated recently
