## From first call to product launch

<div class="steps-row"><div><b>01 · Explore</b><p>Try the Earn lifecycle and choose the right integration path.</p></div><div><b>02 · Connect</b><p>Attribute users, read yield data and connect partner reporting.</p></div><div><b>03 · Operate</b><p>Verify events, reconcile balances and prepare your launch.</p></div></div>

The **Partner API** connects your backend to users, activity, yield information and partner economics. The **sandbox** gives your team a working environment for trying positions and withdrawals before the settlement integration is configured. [Choose your environment](/start/environments/).

## Tools that fit your stack

Use REST directly or work with the [TypeScript and Python SDKs](/sdks/). Both expose response metadata, typed errors and webhook signature verification. The API reference and downloadable schemas keep the implementation details close to the examples.

When you are ready to connect real customer flows, bring your wallet model, asset, network and product requirements to an [integration review](/operate/launch/).
