CowriePay API

CowriePay API

CowriePay is a stablecoin collection and settlement API for businesses that move money in stablecoins, with compliance built in. You create deposit addresses on TRON, BNB Chain or Ethereum; we watch them confirm on-chain, sweep them to custody and credit your workspace balance; and you withdraw when you choose.

Every request is signed with HMAC-SHA256. Sandbox and Live share one host and one code path: the prefix of the API key you sign with decides which network you are on, cpk_test_ for testnet and cpk_live_ for mainnet.

Why teams pick CowriePay

  • Integrate against the real chain from day one. The Sandbox is the real testnets with a built-in faucet: what you test is what runs in production.
  • Money moves safely by default. Deposit provenance screening, a withdrawal allowlist that starts ON, double approval for large withdrawals, and a full audit trail.
  • Built for African stablecoin flows. USDT on TRON first, where stablecoins actually circulate, plus BNB Chain and Ethereum with USDC and EURC.

One naming note if you arrive from the website: what it presents as Collections and Payouts are, in this API, plain deposits and withdrawals.
