How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the echoed mid price, the echoed fill price, a schema identifier string ('delx/util-slippage-bps/v1'), and the computed slippage_bps as a floating-point number representing how many basis points the fill deviated from the mid price.
Example use cases
DeFi swap execution quality check
“I just swapped on-chain and got a fill at 2051.50 against a mid of 2050. How many basis points of slippage did I take?”
Algorithmic trading audit
“Our algo filled a limit order at 98.75 when the mid was 98.50 — can you tell me the slippage in bps so I can log it for the post-trade report?”
Market maker spread analysis
“If my mid price is 500 and the fill price is 501.25, what is the slippage in basis points?”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/slippage-bps?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, pay-per-call, no-signup computation of slippage in basis points between a mid price and a fill price — especially in agent workflows that handle trade execution analysis, DeFi post-trade reporting, or execution quality monitoring where a lightweight on-demand API call is preferred over in-house arithmetic or heavier analytics platforms.
Side effects
- Missing required fields (mid or fill) returns a validation error
- Non-numeric or malformed input values may cause a 400 bad request
- Payment not included or insufficient USDC payment via x402 protocol results in a 402 Payment Required response
- Service unavailability or upstream errors may return 5xx responses
