  1. Usage & Installation

Looking up CIDs

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>

Both will return the CID for the block or transaction if present or HTTP 404 if the TX or slot is unavailable.
