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 trade side, the schema identifier (delx/util-exec-quality-vs-twap/v1), and the computed slippage expressed in basis points (e.g. slippage_bps: 50). Positive values indicate adverse slippage; the sign convention follows standard market microstructure convention for the given side.
Example use cases
Post-trade execution slippage audit
“We executed a sell order with an average fill of 99.80 and the TWAP was 100.10 — can you calculate how many basis points of slippage we incurred on that sell?”
Algorithmic strategy performance review
“I'm reviewing how our algo performed today: we were buying and got an average fill of 50.75 against a TWAP benchmark of 50.60. What's the slippage in bps?”
Real-time agent trade quality check
“After each trade the agent executes, I want it to immediately check execution quality — we just did a buy with avg fill 1023.40 and TWAP was 1021.00. What's the slippage in basis points?”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/exec-quality-vs-twap?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call computation of execution quality measured in basis points against a TWAP benchmark, without building your own formula. It is ideal for AI trading agents that need verifiable, schema-stamped slippage metrics per trade at near-zero cost ($0.001 USDC). Prefer it over rolling your own math when you need an auditable, schema-versioned result suitable for logging or downstream compliance reporting.
Side effects
- Missing required fields (side, twap, avg_fill) return a 400-level error
- Invalid side value (not 'buy' or 'sell') causes a validation error
- Non-numeric twap or avg_fill values cause a schema validation failure
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Network or infrastructure timeout returns a 5xx error
