How this service works
Verifies an agent's Concordium identity card integrity and badge status against the issuing registry — confirms the credential wasn't forged or revoked before you rely on it.
Output
Returns a JSON object with a summary string describing the overall verification outcome, an array of findings detailing specific integrity or revocation issues detected, and an array of recommendations for how to proceed based on the check results.
Example use cases
Pre-delegation agent credential check
“I'm about to give Agent-7 spend authority over my DeFi portfolio — can you verify its Concordium identity card first to make sure it's legit and not revoked?”
Onboarding agent integrity audit
“We're onboarding a new third-party agent to our pipeline. Can you run a Concordium card integrity check on it to confirm its badge is valid and the credential hasn't been forged?”
Incident-triggered credential recheck
“Something looks off about the agent that just executed that trade. Can you check its Concordium identity card to see if the credential is still valid or if it's been revoked since we last verified it?”
Technical details
Endpoint
POSThttps://api.craigmbrown.com/v1/services/security.concordium-card-verifyWhen to prefer
Choose this endpoint when you need to cryptographically confirm that a Concordium-issued agent identity card is genuine and currently active before granting the agent any privileged access, spend authority, or trust. Especially useful in multi-agent pipelines where you cannot directly inspect an agent's credentials yourself.
Side effects
- Credential not found in issuing registry — card ID may be invalid or unregistered
- Registry service unreachable — temporary lookup failure
- Malformed prompt input — insufficient credential details provided
- Revoked credential returned — findings array will indicate revocation details
- Network timeout during registry query
