THE CANTON NETWORK API

Canton Network data, without running a node.

Transparent gives builders fast, reliable access to Canton Network data through a plain JSON API — no participant node to run, no infrastructure to manage. Pay only for the calls you make with prepaid credits or x402, and earn a share by connecting your own node to the pool.

WHY TRANSPARENT

Metered API access that pays its own way.

Built for teams and agents that need fast, reliable access to Canton Network data without running a node. Usage is metered per call and stays auditable on the ledger, so you can reconcile whenever you want.

NO INFRA
No node to run
Query Canton Network data through a single API. No participant node to deploy, no infrastructure to operate or keep in sync.
NO SDK
Just the JSON Ledger API
Point Canton Ledger API v2 requests at your URL — your key rides in the path, so there are no auth headers to rotate in code.
