ZenLedger is a Seattle-founded crypto tax and digital-asset accounting company whose platform ingests transactions from 400+ exchanges, 100+ DeFi protocols and 10+ NFT marketplaces to calculate cost basis, capital gains and income, and generate US tax forms. Beyond the consumer product it operates two documented B2B REST APIs on api.zenledger.io: the Compliance Suite API (v3), a digital-asset trade-monitoring surface built with COMPLY for financial institutions and enterprise compliance teams that registers companies and users, imports wallets and exchange accounts, returns normalized transactions and holdings, and screens blockchain addresses against sanctions lists; and the Aggregator Suite API (v1), a partner surface that builds an aggregated portfolio from a set of accounts and returns the resulting tax calculation. Both authenticate with OAuth 2.0 client_credentials JWTs and are documented as versioned Postman collections at docs.zenledger.io.
