How this service works
Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.
Output
Returns a JSON object with an 'ok' boolean indicating whether the verifiable credential is valid. A truthy response confirms the credential passed verification; a falsy or error response indicates the credential is invalid, expired, or tampered with.
Example use cases
Gating access with credential check
“Before letting this user into the platform, verify their verifiable credential and tell me whether it checks out — here's the VC JSON they submitted.”
Onboarding identity verification flow
“As part of onboarding, I need to confirm that the credential this applicant provided is authentic and hasn't been tampered with — can you run a VC verification on this JSON payload?”
Agent-to-agent credential handshake
“My agent received a verifiable credential from a partner agent claiming a certain identity — please verify that credential and let me know if the ok flag comes back true.”

Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/identity/vc-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, machine-payable (x402) on-demand verifiable credential (VC) verification step inside an agentic workflow — particularly when you want to verify W3C-style VCs without standing up your own DID/VC infrastructure. Best suited for agents that need to gate access, onboard users, or perform trust checks on identity credentials at $0.001 per call.
Side effects
- Malformed or missing VC body returns a validation error
- Invalid credential signature causes verification failure with ok: false
- Expired or revoked credential may return ok: false or an error status
- Missing required fields in body causes schema rejection
- Network or service errors may return non-2xx status codes
- Payment failure (x402) if USDC balance is insufficient
