How this service works
Capture, verify, approve, and export audit-ready evidence packs for credit, compliance, and financial operations.
Output
Returns a JSON object containing: success and verified boolean flags, a sealed SHA-256 proof hash (e.g. PROOF-87B43B8D...), the network (Base), a protocol token contract address, and a link to the nodes portal for further verification.
Example use cases
Sealing a loan approval for audit
“We just approved a mortgage application and need an immutable, audit-ready receipt with a cryptographic hash — can you run this through ProofAudit so we have a sealed PROOF record for the regulator?”
Compliance evidence pack for a credit review
“Our compliance team needs a verified, exportable evidence pack showing that this credit decision was properly captured and sealed — can you generate one via ProofAudit with the SHA-256 seal?”
Proving a financial workflow approval occurred
“I need to demonstrate to our auditor that a specific payment approval happened and was cryptographically verified — can ProofAudit give me a sealed proof token and verification status I can include in our audit file?”
Technical details
Endpoint
GEThttps://proofaudit.ai/api/x402?utm_source=zero.xyzWhen to prefer
Choose ProofAudit when you need cryptographically sealed, tamper-evident audit trails for financial approvals, credit decisions, or compliance workflows — especially when regulators or auditors require exportable evidence packs with verifiable SHA-256 hashes anchored to the Base blockchain. Prefer this over generic document storage when immutability and verifiability are required.
Side effects
- Payment not received — returns 402 if the $0.025 USDC x402 payment is missing or malformed
- Invalid HTTP method — only GET, HEAD, and POST are accepted
- Verification failure — verified field returns false if the evidence could not be sealed
- Network unavailability — Base network congestion may delay or fail the sealing operation
- Malformed query parameters — additionalProperties not conforming to string type may be rejected
