How this service works

Synthex Forge x402 Receive: 41 paid verification, attestation and governance endpoints (Ed25519 + SHA-256 signed artifacts) plus free verify/public-key/standard sibling routes. Paid routes answer HTTP 402 with an x402 v2 `payment-required` envelope (atomic USDC on Base mainnet, chain ID 8453). Free routes are declared with `security: []` per the x402scan discovery spec.

Output

A JSON response with an 'ok' boolean indicating success, along with a cryptographically signed attestation artifact secured with Ed25519 and SHA-256. The artifact provides tamper-evident proof of the submitted claim, suitable for audit, compliance, or governance workflows.

Example use cases

Regulatory compliance attestation

“I need to attest our Q3 audit claim through Synthex Forge VeriTrack — claim type is 'regulatory_compliance' and the claim object has our entity ID, audit hash, and jurisdiction field. Give me back the signed artifact for our records.”

Governance decision signing

“Can you submit a governance attestation for the policy change we approved today? The claim type is 'governance_decision' and the claim object should include the proposal ID, approver list, and timestamp.”

Data provenance certification

“I want to certify the provenance of this dataset — use VeriTrack to attest a claim of type 'data_provenance' with the source URI, checksum, and creator wallet in the claim object, and get me back a signed proof.”

When to prefer

Choose this endpoint when you need a cryptographically signed, Ed25519 + SHA-256 attested artifact for a structured claim — especially in governance, compliance, or audit contexts where tamper-evidence and on-chain verifiability are required. It is preferable over generic signing services when you need a purpose-built attestation API with x402 micropayment access control and a structured claim schema.

Side effects

HTTP 402 returned if payment header is missing or USDC payment on Base mainnet (chain ID 8453) is insufficient
Malformed claim object returns validation error
Unknown or unsupported claim_type may result in rejection
Network or blockchain settlement delay may cause timeout
Duplicate or replayed claims may be rejected depending on service configuration
