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-vwap/v1), and the computed slippage in basis points (slippage_bps) relative to the VWAP benchmark.
Example use cases
Post-trade execution audit for sell order
“My sell order had an average fill of 101.75 and the VWAP for that period was 102.00 — how many basis points of slippage did I get?”
Buy-side algo performance review
“We ran a buy algo that filled at an average of 45.30, but the VWAP was 45.10. Can you tell me the execution quality slippage in bps?”
Real-time fill quality check during trading
“I just got a partial fill on a sell at 200.80 with a VWAP of 200.50 — what's my slippage versus VWAP in basis points?”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/exec-quality-vs-vwap?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call, no-signup computation of execution slippage in basis points against a VWAP benchmark for a single trade leg. It is ideal for algorithmic trading agents that need verifiable, auditable fill quality metrics at low cost ($0.001 USDC per call) without managing a subscription. Prefer alternatives if you need multi-leg slippage, portfolio-level analytics, or integration with a full TCA (transaction cost analysis) platform.
Side effects
- Missing required field (side, vwap, or avg_fill) returns a validation error
- Invalid trade side value (not 'buy' or 'sell') causes rejection
- Non-numeric vwap or avg_fill values return a parsing error
- Payment failure via x402 protocol blocks execution
- Zero or negative price values may produce undefined or erroneous slippage results
