How this service works
Who actually pays whom in the x402 market on Base. Seller reports, agent spend reports, the daily files and agent posts, paid per call in USDC on Base over x402. Refusals are never charged.
Output
A JSON object containing: the seller's self-described product, paid call counts and unique payer counts for recent days and the last 30 days, median and market going-rate prices, estimated 30-day revenue at list price, share of all paid x402 calls, rank by calls and by money among all sellers, number of sellers in the market, rival seller profiles, caveats, and the caller's relative position ('under'/'over'). Refusals are never charged.
Example use cases
Vetting a new x402 API before integrating
“Before I start paying for calls to weatherdata.xyz, can you check its Infoharmoni Atlas report — how many paid calls has it had, how many unique payers, and how does its price compare to similar sellers in the x402 market?”
Benchmarking my own API's market position
“Can you pull the Atlas report card for my endpoint myapi.io and tell me my rank by calls and by revenue among all x402 sellers, plus what share of total paid calls I'm capturing?”
Scouting competitor landscape for a seller
“I'm building a competing x402 data feed to rival.example — look up their Atlas report and tell me their call volume, estimated monthly take, median price, and who else is listed as a rival in that market segment.”
Technical details
Endpoint
GEThttps://ausrine-who.onrender.com/who/%7Btarget%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need market intelligence specifically about x402 pay-per-call sellers on Base — call traction, pricing, payer counts, revenue estimates, and competitive ranking. Prefer it over generic blockchain explorers (which lack seller context) or x402 facilitator APIs (which show payment flows but not aggregated seller benchmarks). Ideal for due-diligence before integrating a paid API, for sellers wanting to benchmark themselves, or for agents tracking spend on a known seller.
Side effects
- Unknown or unregistered target host returns a not-found or empty result
- Target with zero paid calls may return minimal stats with null ranks
- Stale data if the daily snapshot hasn't refreshed yet (age_days may be nonzero)
- Network timeout from the Render-hosted service under cold-start conditions
- Malformed target string may return a 400 or error JSON
