How this service works
Before paying an x402 service: real paid activity of its host or payTo (24h, 7d, 30d, unique payers, volume, first and last payment), observed prices, endpoint health and price or payTo changes, plus daily history.
Output
Returns a structured object containing: real payment activity metrics (24h, 7d, 30d windows) including payment count, unique payers, and USDC volume; first and last payment timestamps; observed prices from 402 challenges; current endpoint health status; any detected price or payTo address changes; and daily historical payment data for trend analysis.
Example use cases
Due diligence before first payment
“I'm about to pay api.datafeeds.io for their x402 stock data service — can you pull its real payment activity for the past 30 days, any observed price changes, and whether the endpoint is still healthy before I commit?”
Verify wallet address legitimacy
“Check the x402 payment history for this payTo address 0xAbCd1234567890abcdef1234567890abcdef1234 — I want to see unique payer count, total volume, and when the first and last payments happened.”
Monitor price drift on a live service
“Has the price for api.llmproxy.xyz changed recently? Pull the observed prices and daily history from AgentsMap so I can see if it's crept up since I last checked.”
Technical details
Endpoint
POSThttps://agentsmap.io/semilla/x402/seller?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or human needs to vet an x402 API before paying for it — checking whether it has real historical usage, consistent pricing, and a healthy status. Prefer this over raw on-chain lookups when you need aggregated multi-window metrics (24h/7d/30d), price change detection, and daily history in a single call. It is specifically designed for the x402 protocol ecosystem on Base and is the right choice when you have either a seller host domain or a payTo wallet address.
Side effects
- Host or payTo not indexed — returns empty or null activity data if the seller has never been crawled
- Invalid payTo address format — rejected by schema validation (must match 0x hex pattern)
- Neither host nor payTo provided — endpoint may return an error or empty result
- New/inactive seller — zero payment activity returned, not an error but may look like failure
- Service temporarily unavailable — HTTP 5xx from upstream
