How this service works
Check whether an AI agent is registered, Active and Verified in the Concordium Agent Registry (CIS-8004).
Output
Returns a JSON object indicating whether the queried badge or account was found in the Concordium Agent Registry, along with: found (bool), active (bool), verified (bool), owner address, agent URI (well-known agent card URL), token ID, token address, whether the agent card hash matches on-chain data, the network queried, and any issues detected. Also indicates if the result is mocked.
Example use cases
Verify agent before autonomous handoff
“Before we let this external agent handle the transaction, check if badge Mf22soLh1NuZYFgBK8iSs is active and verified in the Concordium Agent Registry on mainnet.”
Validate testnet agent during development
“We're testing our new agent — can you look up badge address 4DDvjwdcLmTy1Ar9FCKKPMiABrS261TvyXJGr4n4ypuuogXeFF in the Concordium registry on testnet and tell me if it shows as active and verified?”
Confirm agent identity before payment
“I need to pay this AI agent service, but first confirm its Concordium badge Mf22soLh1NuZYFgBK8iSs is registered and verified on mainnet so I know it's legitimate.”
Technical details
Endpoint
GEThttps://agentgate.agentgate.workers.dev/v1/check-agent?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to confirm the legitimacy and status of an AI agent in the Concordium CIS-8004 registry before initiating interactions, payments, or delegating tasks to it. It is the canonical trust check for Concordium-based agent ecosystems and should be preferred over generic blockchain lookups when the agent uses CIS-2 badge tokens or Concordium account addresses as identifiers.
Side effects
- Badge or account address not found in registry (found: false)
- Invalid or malformed badge/address format causes 400 error
- Network parameter value not recognized
- Agent found but not active (active: false) — agent is registered but inactive
- Agent found but not verified (verified: false) — registration incomplete
- cardHashMatches: false — agent card has been tampered with or is out of sync
- Concordium network node unavailable causing upstream timeout
