How this service works
Paid agent-facing brief on post-settlement x402 audit trail standard: durable, verifiable record after payment settles. Schema: evidence chain binding tx hash, facilitator, quoted price hash, invoice id, deliverable hash, payer and seller identifiers, settlement timestamp; chain-of-custody append rules, retention windows, offline verifiability without the seller's server, and how to reconstruct the audit trail months later from independent sources (block explorer, facilitator receipt, local
Output
A prose decision-procedure brief covering the x402 post-settlement audit trail standard, including: the evidence chain schema (tx hash, facilitator, quoted price hash, invoice ID, deliverable hash, payer/seller identifiers, settlement timestamp), chain-of-custody append rules, retention windows, offline verifiability procedures, and step-by-step instructions for reconstructing the audit trail months later from independent sources such as block explorers, facilitator receipts, and local records.
Example use cases
Agent verifying old x402 payment offline
“Walk me through how I can verify that an x402 payment from three months ago actually settled correctly, using only the block explorer and facilitator receipt — without calling the seller's server at all.”
Building compliant x402 payment records
“What fields do I need to include in my post-settlement audit record to meet the x402 audit trail standard? I want to make sure I'm capturing the tx hash, quoted price hash, invoice ID, deliverable hash, and payer and seller identifiers correctly.”
Reconstructing audit trail after dispute
“I need to reconstruct a complete chain-of-custody audit trail for an x402 transaction that's being disputed — explain the standard append rules and which independent sources like block explorers and facilitator receipts I should pull from.”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/post-settlement-x402-audit-trail-standard-durabl?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs authoritative, structured guidance on x402 post-settlement audit trail standards — specifically the evidence chain schema, offline verification, and multi-source reconstruction procedures. Prefer over generic documentation when you need a machine-readable brief formatted for agent consumption, or when implementing compliance logic that must survive seller-server unavailability.

- Payment required (402) if x402 micropayment not provided
- Invalid method — only GET/HEAD/DELETE accepted
