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
Returns a JSON object with an 'ok' boolean indicating success, along with any matched evidence query results tied to the specified actor DID from the sealed evidence store.
Example use cases
Compliance audit for a DID
“Pull all sealed evidence entries we ingested for the actor DID 'did:key:z6MkhaXgBZDvotDkL5257faiztiGiC2QtKLGpbnnEGta2doK' and tell me what the attestation results show.”
Governance review of actor records
“I need to query our evidence archive for the actor 'did:web:example.org' — can you run a lookup against the sealed entries we submitted last week and show me what comes back?”
Verify evidence before onboarding
“Before we onboard this new partner, query the sealed evidence entries we have on file for their DID 'did:ethr:0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B' and confirm whether attestation passed.”
Technical details
Endpoint
POSThttps://x402.synthexforge.com/v1/evidence/query?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to query previously ingested, cryptographically sealed evidence entries tied to a specific actor DID with Ed25519 + SHA-256 signed artifacts. Prefer this over generic database lookups when you need tamper-evident, attestation-grade evidence retrieval with governance guarantees in a decentralized identity context.
