ZenLedger Compliance Suite API
Digital-asset trade-monitoring and crypto tax-compliance REST API (v3) for financial institutions and enterprise compliance teams. Registers companies and their users, imports exchange accounts and wallets over a signed and AES-256 encrypted request, returns normalized transactions and per-source holdings, screens blockchain addresses against sanctions lists, exposes Polymarket positions, and serves supported currency, source and chain reference data. Authenticated with an OAuth 2.0 client_credentials JWT that expires in 30 minutes. Import completion, import-limit and wallet-screening events are delivered as webhooks.
