x402
PriorSeal Verification Bundle Retrieval is a paid API for AI agents from priorseal.xyz, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).
Retrieves a portable, independently verifiable authorization-and-execution bundle for a given PriorSeal receipt, linking pre-execution authorization to observed EVM/Solana execution with a cryptographic bundle hash.

How this service works
Connect explicit, pre-execution authorization to observed EVM and Solana execution with portable evidence another party can verify independently.
Output
Returns a JSON object conforming to the priorseal.verification-bundle.v1 schema, containing: the schema identifier, the receipt object (with receiptId and executionStatus), a 64-character hex bundleHash, and a keyRegistry listing the signing keys used. This bundle is self-contained and portable so a third party can independently verify the authorization-to-execution linkage without calling PriorSeal again.
Example use cases
Audit trail for on-chain agent action
“I need to prove to our compliance team that the EVM transaction last Tuesday was pre-authorized — can you fetch the PriorSeal verification bundle for receipt psr_abc123 so we have the bundle hash and execution status ready to hand over?”
Cross-party authorization verification
“Our counterparty wants to independently verify that the Solana execution was authorized before it happened — pull the PriorSeal bundle for receipt psr_xyz789 and share everything they need to check it themselves.”
Checking receipt execution status
“Can you look up receipt psr_def456 in PriorSeal and tell me whether the execution is marked as COMPLETED and what the bundle hash is?”
Technical details
Endpoint
GEThttps://priorseal.xyz/v1/receipts/%7BreceiptId%7D/bundle?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a portable, self-contained cryptographic evidence bundle that proves a pre-execution authorization existed and links it to an observed EVM or Solana execution — especially when a third party (auditor, counterparty, regulator) needs to verify the chain of authorization independently without trusting PriorSeal directly. Prefer it over generic block explorers or transaction lookup APIs when authorization provenance (not just transaction existence) is what matters.
Side effects
- Receipt ID not found — returns 404 if the receiptId does not exist or has not been created yet
- Invalid receiptId format — returns 400 if the ID is empty or exceeds 512 characters
- Unauthorized — returns 401/402 if the x402 payment has not been completed or the payment is invalid
- Bundle not yet generated — receipt may exist but execution is still in progress, returning an incomplete or pending status
- Network/service error — returns 5xx if PriorSeal infrastructure is temporarily unavailable
