Removal of API AMM slippageTolerance Cap
Posted: August 20, 2026 | Effective: August 21, 2026
The slippageTolerance field will allow any value from 0 to 100, inclusive, with up to two decimal places of precision. This will be applied correctly to AMM orders.
What is changing?
The slippageTolerance field on the /quote request was previously capped at 20% (20) for AMM orders. /quote requests with slippage set higher than 20% would fail with "No quotes available," or would fall back to UniswapX if allowed by the request. After this change, you can set slippage as high as 100% and still receive an AMM response.
Requests with slippage below 0, above 100, using more than 2 decimal places, or providing a non-number will continue to fail with a field validation error.
Why is this changing?
The silent failure behavior was misleading and prevented integrators from offering wider slippage ranges to their end users.
What do I need to do?
No change is required for existing integrators. You may continue to keep your own slippage caps in your interface, or allow users to set any slippage from 0% to 100%.
