How this service works
One x402 seller's report card before you pay them: what they sell, paid calls and payers in 30 days, price, rank of all sellers, rivals, and the day-by-day replay nobody else stored. Stamped with the snapshot date. Refusals are free.
Output
Returns a structured seller report card including: what the seller offers, number of paid API calls in the past 30 days, count of unique payers, listed price, rank among all sellers on the marketplace, a list of rival/competing sellers, a chronological day-by-day activity replay, and the timestamp of when the snapshot was taken. Failed lookups (refusals) are free.
Example use cases
Vetting a seller before first payment
“I'm about to pay an x402 seller for the first time — can you look them up and tell me their paid call count, unique payers, price, and seller rank for the past 30 days so I know if they're legit?”
Comparing rival sellers on x402
“Who are the top rivals to this x402 seller and how do their stats compare — calls, payers, and rank?”
Reviewing daily activity replay
“Can you pull the day-by-day breakdown of this x402 seller's activity over the last 30 days so I can see if their traffic is consistent or just a one-day spike?”
Technical details
Endpoint
GEThttps://ausrine-who.onrender.com/who/:target?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need due-diligence data on a specific x402 marketplace seller before committing a payment — especially when you want historical call volume, payer diversity, price, rank, rivals, and day-by-day replay in a single call. Prefer this over generic blockchain explorers or marketplace pages when you need structured, agent-readable seller analytics with a 30-day rolling window.
Side effects
- Unknown or invalid target seller identifier — returns refusal at no cost
- Seller has zero activity in the 30-day window — may return sparse or empty stats
- Snapshot data may be slightly stale depending on when it was last captured
- Network timeout if the Render-hosted service is cold-starting
