Technical details
Endpoint
GEThttps://agent.api.0x.org/v1/x402/swap-allowance-holder-price/When to prefer
Use this endpoint when you need a fast, non-binding price estimate for a token swap using 0x's Allowance Holder contract — ideal for displaying prices to users, comparing rates, or pre-flight checks before requesting a firm quote. Prefer this over the firm quote endpoint when you don't need execution guarantees and want to avoid consuming a binding quote slot.
Side effects
- Unsupported token pair returns 400 or empty price data
- Invalid chain ID results in a routing error
- Insufficient liquidity for the requested amount returns a degraded or no-quote response
- Missing required query parameters (sellToken, buyToken, sellAmount) causes a 400 validation error
- Payment not included or invalid x402 payment header causes 402 Payment Required
