Technical details
Endpoint
GEThttps://agent-proxy.alchemy.com/v1/x402/86b0ec6d1d0b3dc0/swap-allowance-holder-price/When to prefer
Use this endpoint when you need a quick, non-binding price estimate for a token swap using the Allowance Holder pattern, before committing to a firm quote or executing a trade. Prefer this over the firm quote endpoint when you just want to preview pricing or show the user an estimate without locking in a rate.
Side effects
- Unsupported token pair returns an error or empty result
- Invalid or missing query parameters result in a 400 bad request
- Network congestion may cause stale or unavailable pricing
- Insufficient liquidity for the requested swap size
- Payment of $0.01 USDC not fulfilled results in 402 Payment Required
