How this service works
Measurement history for one x402 merchant: state, settlement txid, latency, advertised price and price actually charged, purchase by purchase
Output
A list of per-purchase measurement records for the specified x402 merchant, each containing: settlement state (e.g. settled or failed), settlement transaction ID, end-to-end latency, advertised price at time of purchase, and the price actually charged. Records cover the merchant's full measurement history ordered by purchase.
Example use cases
Auditing merchant settlement reliability
“Show me the complete purchase-by-purchase history for x402 merchant def456 — I want to know how often payments actually settled and if there were any discrepancies between the advertised and actual price.”
Investigating a disputed x402 charge
“I think I was overcharged by x402 merchant xyz789. Can you pull the measurement history and show me the advertised price vs what was actually charged for each transaction, along with the settlement txid?”
Monitoring latency for a high-frequency merchant
“Give me the full history of measurements for x402 merchant mno321 — I'm especially interested in the settlement latency per purchase to see if it's gotten worse over time.”
Technical details
Endpoint
GEThttps://whaletape.xyz/index/merchant/:idWhen to prefer
Use this endpoint when you need granular, per-transaction audit data for a specific x402 merchant — including settlement confirmation, on-chain txid, pricing accuracy, and latency. Prefer this over the aggregate settlement-rate ranking endpoint when you need the full purchase-level detail rather than a summary score.
Side effects
- Merchant ID not found — returns empty or 404-style response
- Merchant has no recorded purchases yet — returns empty array
- Invalid merchant ID format — returns error
- Upstream data unavailable — intermittent service errors possible at $0.02/call cost
