# Add swaps to your product

> Three ways to integrate LightSwap: the widget, the Direct API, or a referral link. Pick the one that fits your product.

LightSwap gives businesses three ways in. All three are self-serve. The widget and the API start from **Account → Business** on [lightswap.me](https://lightswap.me/account); referral links live in **Account → Referrals**.

## Choose your integration

|                 | Widget                      | Direct API           | Referral link        |
| --------------- | --------------------------- | -------------------- | -------------------- |
| Setup time      | Minutes                     | A day of development | None                 |
| What you need   | A webpage                   | A backend            | An audience          |
| User experience | Hosted swap UI on your page | Fully your own UI    | LightSwap website    |
| You earn        | 0.5% of swap volume         | 0.5% of swap volume  | 0.25% of swap volume |

**Widget.** An iframe that puts the full swap flow on your page. No backend, no API key. Add a public widget key and completed swaps earn you commission. [Widget docs](/integrations/widget/introduction).

**Direct API.** Your backend creates quotes and swaps, your UI stays entirely yours. Built for wallets, exchanges, aggregators, and payment products. Start with the [quickstart](/business/quickstart).

**Referral link.** No integration at all. Share your link and earn from swaps your audience makes on LightSwap. Individuals use this too. [Referrals](/account/referrals).

## What partners get

* A flat **0.5% of completed swap volume**, credited in USDC, for API and widget integrations.
* A dashboard with attributed volume, swap count, fee history, and payout history.
* Claims from **10 USDC**, paid to your LightSwap account balance.

Details and payout mechanics: [Revenue sharing](/business/revenue-sharing).

## What the API covers today

The Direct API handles the full swap cycle: list assets, validate addresses, create quotes, create swaps, poll status, and pull swap history for reconciliation. It does not yet offer webhooks or per-request custom fees. The full list is on the [Direct API introduction](/integrations/direct-api/introduction).
