# Limits

> Review current LightSwap API MVP limits for quote type, polling, commission setup, API keys, memos, and support handoff.

The API MVP is intentionally small. It covers backend quote-driven swap creation and status polling.

## Current limits

| Area             | Current behavior                                   |
| ---------------- | -------------------------------------------------- |
| API keys         | Backend-only API keys.                             |
| Quote type       | Exact-input floating quotes only.                  |
| Quote lifetime   | Short-lived quotes with an `expiresAt` timestamp.  |
| Commission       | Configured during onboarding and commercial setup. |
| Status updates   | Poll `GET /swap/{id}`.                             |
| Destination memo | Not supported in the MVP.                          |

## Integration defaults

* Poll active swaps every 30 seconds.
* Store the LightSwap swap ID with your own order ID.
* Treat all amounts as decimal strings.
* Refresh supported assets regularly instead of hardcoding asset lists.

## Fees and network costs

The API returns the route estimate and deposit instructions for the swap. Wallet, gas, and blockchain network costs are separate third-party costs and can change outside LightSwap.

## Support handoff

When you contact support, include:

* Your `externalId`, if you sent one.
* LightSwap swap ID, if one exists.
* Deposit transaction hash, if the user has already sent funds.

Do not include private keys, seed phrases, or full internal customer records.
