CID Lookup API

Support for these endpoints is currently in progress.

You can look up CIDs for individual slots or transactions by using our hosted service:

• Transaction signatures: https://cid.old-faithful.net/api/v1/sig-to-cid/<sig>

• Blocks: https://cid.old-faithful.net/api/v1/slot-to-cid/<slot>

If the CID is available, the API will return the CID for the block or transaction.

A HTTP 404 response indicates the transaction or slot is unavailable in Old Faithful.
