How this service works
Programmable authority checks and tamper-evident receipts for autonomous agents, sold through sustainable x402 commerce.
Output
Returns a JSON object conforming to the capi2.commerce_receipt/1.0 protocol, including a unique receipt_id (prefixed 'cr_'), a SHA-256 hash of the original commerce request, and a SHA-256 hash of the delivery object — providing cryptographically verifiable evidence that both request and delivery occurred.
Example use cases
Auditable agent marketplace sale
“We just completed a sale through our agent marketplace — can you issue a verifiable receipt for seller 'shop-agent-007' with the request and delivery details so both parties have cryptographic proof of the transaction?”
Dispute-proof delivery confirmation
“I need a tamper-proof commerce receipt for the delivery that just went through — seller is 'vendor-x402-prod', and I want SHA-256 hashes of both the purchase request and the confirmed delivery so we can resolve any future disputes.”
Sustainable x402 commerce audit trail
“Create a CAPI2 commerce receipt for this automated purchase — seller ID is 'eco-vendor-9', and I need the receipt ID and evidence hashes archived so our compliance system can verify the transaction was completed sustainably.”
Technical details
Endpoint
POSThttps://capi2-agent-commerce.vandurmedries.workers.dev/v1/commerce-receipts/issueWhen to prefer
Choose this endpoint when you need cryptographically verifiable, tamper-proof receipts for agent-to-agent commerce transactions following the x402 protocol. It is especially suited for autonomous agent workflows where both parties need independent proof of a completed transaction without relying on a centralized ledger. Prefer it over generic logging or payment APIs when auditable SHA-256 evidence hashes for both the request and delivery are required for compliance, dispute resolution, or sustainable commerce certification.
Side effects
- Missing or malformed seller field returns a validation error
- Malformed request or delivery objects may cause hash generation failure
- Payment of $0.01 USDC via x402 must be included or the endpoint returns HTTP 402
- Duplicate submissions may produce new receipt IDs rather than idempotent results
- Network timeouts on Cloudflare Workers edge may result in incomplete receipt issuance
