Create a batch of credentials

Submit one or more credentials for signing and anchoring. The endpoint returns immediately; signing + anchoring complete asynchronously, typically within 60 seconds on testnet. Subscribe to `batch.anchored` webhooks rather than polling.

Retrieve a credential

Returns the credential's current status plus the signed JSON-LD document (same artifact consumed by the public `/c/{id}` verification page and by any Blockcerts-compatible verifier).
