Reference
The hosted Attestra API.
Ask whether a credential is valid, who issued it, or what an issuer registered. Attestra reads the answer from the chain that holds it, signs it, and returns it.
You do not pick a chain. The DID method routes the request.
| Chain | DID method | Underneath |
|---|---|---|
| eIDChain | did:eid:… | Substrate |
| Ethereum | did:ethr:… | ERC-1056 |
| Hyperledger Fabric | did:fabric:… | Fabric Gateway |
Quick start
curl https://<host>/v1/resolve/did:eid:4tARKz6hK5GuWr9fkdzsG1Bf9X3b3agzh7RPBdjdpLWapHRh \
-H "Authorization: Bearer idc_live_..."Create an account to get a key, then read Authentication. HTTP and WebSocket pass the key differently, and the reason matters.
What costs what
Verification questions are answered off chain and signed. Nothing is written and no gas is spent. Only Push sends a transaction.
Every call burns one credit unless it fails with a 5xx, which is not billed. See Credits and billing.
