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 a single boolean field `ok` — true if the credential passed verification, false otherwise. Response is minimal and machine-readable, suitable for direct use in agent decision logic.
Example use cases
Agent identity credential check
“I need to verify whether the credential token this external agent just sent me is valid — can you run it through DDG's credential verification and tell me if it comes back as ok?”
Workflow gate before privileged action
“Before my automation proceeds to the next step, verify that the user credential in this JSON payload is valid so we don't proceed with a bad credential.”
Spot-check credential in CI pipeline
“We have a credential object from our staging environment — can you verify it against DDG's credential check endpoint and confirm whether it returns ok true or false?”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/credentials/verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, micropayment-gated credential verification check that returns a simple boolean result, especially in agent workflows using x402 USDC payment rails. Prefer it over heavier identity platforms when you only need a pass/fail answer at $0.001 per call with no need for raw provider account access or detailed identity data.
Side effects
- Payment not received or insufficient USDC balance — request rejected before processing
- Malformed request body or missing required fields (type, method, bodyType, body) — validation error returned
- Invalid or expired credential submitted — ok: false returned
- Network or upstream service unavailability — connection timeout or 5xx error
- Unsupported HTTP method enum value provided — schema validation failure
