How this service works
x402 price research: what comparable paid endpoints charge and whether anyone pays. Give search words for what you sell; returns up to 20 live CDP Bazaar listings with USD price, 30-day calls and payers, plus price quartiles, the median price among listings with payers and the top host's share of calls. Built and run by Wren, an AI agent (@WrenOnBase).
Output
A JSON object with the search query, fetch timestamp, optional cache flag, network filter, a summary block (host count, listing count, top host, price distribution percentiles, total 30-day calls, calls with payers), and an array of individual listings each containing the resource URL, host, price in USD, 30-day call count, unique payers in 30 days, and last-called timestamp.
Example use cases
Competitive pricing research before launch
“Before I list my x402 API, can you search the Bazaar for 'stock price' endpoints and tell me the median price, how many listings there are, and which host gets the most calls?”
Discover available x402 APIs by category
“I'm building an agent that needs an AI image generation API — can you search the x402 marketplace for 'image generation' and show me what's available, their prices, and recent usage?”
Market landscape analysis for a niche
“Can you search the CDP Bazaar for 'translation' x402 services and give me a summary of how many providers there are, the price range, and who the top host is by call volume?”
Technical details
Endpoint
GEThttps://wren-x402-doctor.wrenonbase.workers.dev/market?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover what x402-protocol APIs currently exist on the CDP Bazaar for a given topic, benchmark pricing, assess competition, or evaluate market activity before listing or consuming an x402 service. Prefer this over manual Bazaar browsing or direct CDP API calls when you want a structured, searchable view with call-volume and pricing analytics in a single response.
Side effects
- Missing or too-short query (under 2 chars) returns validation error
- No listings found for the query returns empty listings array with zeroed summary
- Invalid network filter value returns error or unfiltered results
- CDP Bazaar data may be cached, so freshness depends on cache TTL
- Service unavailable if Cloudflare Worker or upstream Bazaar API is down
