How this service works
Everything one x402 seller (origin) lists: its APIs with prices, payers and uptime, its total calls, its payTo addresses, and since when it is listed.
Output
A JSON object containing the seller's origin URL, total number of listed APIs, an array of individual API resources each with its price in USD and 30-day payer count, aggregate 30-day call volume, mean uptime over 30 days, and payTo address(es) with listing date.
Example use cases
Vetting a new x402 API vendor
“Before I integrate with https://llm.someprovider.ai, can you pull their x402 seller profile so I can see how many APIs they list, what each one costs, how many payers they have, and what their 30-day uptime looks like?”
Tracking a competitor's API catalog
“What APIs is https://api.rivalservice.com selling on the x402 market right now, and how do their prices and payer counts compare across each endpoint?”
Auditing payTo addresses for an x402 seller
“I need to verify the payTo wallet addresses for the x402 seller at https://data.trustedvendor.io — can you fetch their full seller profile and show me those addresses along with when they first got listed?”
Technical details
Endpoint
GEThttps://tb2s28fm0h8dkq2t.68r.lambda-web.us-east-1.on.aws/v1/seller?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the complete profile of a single known x402 seller by its origin URL — including its full API catalog, per-API pricing and payer counts, aggregate call volume, uptime, and payTo addresses. Prefer this over the rankings or trending endpoints when you have a specific origin in mind and want exhaustive per-seller detail rather than cross-market comparisons.
Side effects
- Origin not found in registry — returns empty results or 404-equivalent if the origin has never been listed
- Malformed origin URL (missing https:// scheme or exceeds 300 chars) — request rejected with validation error
- Seller has no active listings — returns valid response with empty results array and zero counts
- Payment failure ($0.003 USDC not fulfilled) — request blocked with 402 Payment Required
- Upstream data freshness lag — uptime and payer counts reflect rolling 30-day window and may be up to 6 hours stale
