## Trading API

### `route_not_found`

This error is most common in two situations:

1. **Incorrect `amount` units.** The `amount` parameter is the `inputMint`
   amount in atomic units (scaled by decimals). If you pass standard
   (human-readable) units (for example `8` instead of `8_000_000`), the router will not find a viable route.

2. **No available route.** The router found no viable route between `inputMint`
   and `outputMint`. This can happen for illiquid pairs or when the trade size
   exceeds available liquidity. Try a smaller amount or a different pair.

### `price_impact_too_high`

The effective price during routing is worse than the allowed threshold. If unspecified, the server determines the default. To set your own threshold, pass [`priceImpactTolerancePct`](/resources/trading-api/order/order#parameter-price-impact-tolerance-pct).
