Build against sandbox, then swap the base URL. The endpoint structure is identical, but sandbox uses explicit testnet chain keys such as ethereum_sepolia and may expose a smaller yield-source catalog than production. API Conventions covers authentication, pagination, idempotency, rate limits, and error handling.
