Api Endpoint

Wallet Funding Source Trace

Where did this address get its money? Walks the funding chain upward and returns the account that ultimately paid for the wallet, plus a cluster id. Two addresses funded from the same account are not independent parties, however unremarkable each looks alone — the cheapest strong signal that an identity was manufactured. Works on any address, not only registered agents. Free alternative: GET /v1/provenance. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial.
