How this service works
Execution cost estimate in basis points from supplied spread, fees, participation and impact assumptions. No trade execution or live order book. Idempotency-Key required.
Output
Returns a total execution cost estimate expressed in basis points, computed as a function of half-spread, fees, optional noise, and a power-law market impact term (impact_k × participation^impact_alpha). No live order book or trade is executed; the result is a deterministic analytical estimate for stress-testing and pre-trade analysis.
Example use cases
Pre-trade cost analysis for large BTC order
“I'm planning to buy a large block of BTC at 15% market participation. My spread is 10 bps, fees are 4 bps, impact k is 60 bps, and impact alpha is 0.5. What's my estimated all-in execution cost in basis points?”
Comparing execution cost at different participation levels
“Model my execution cost at 30% participation with a spread of 12 bps, fees of 6 bps, impact k of 80, and impact alpha of 0.7 — I want to know how expensive it gets if I execute more aggressively.”
Stress testing execution assumptions for risk reporting
“Run an execution stress scenario for me: spread 5 bps, fees 3 bps, noise 2 bps, impact k 40 bps, impact alpha 0.55, and participation 0.10 — I need the total cost estimate in bps for our pre-trade risk report.”
Technical details
Endpoint
POSThttps://www.securaw.com/cryptovar/x402/execution_stress?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, analytical execution cost estimate in basis points based on your own spread, fee, impact, and participation assumptions — rather than live market data or actual order routing. Ideal for pre-trade cost analysis, stress testing, quantitative research, and risk reporting workflows where auditability and reproducibility matter.
Side effects
- Missing required fields (spread_bps, fees_bps, impact_k, participation, impact_alpha) returns a validation error
- Values outside allowed ranges (e.g. participation > 1, fees_bps > 10000) are rejected
- Missing or duplicate Idempotency-Key header may cause request rejection
- Payment failure or insufficient USDC balance blocks the call
- impact_alpha must be strictly positive (exclusiveMinimum: 0); zero or negative values are rejected
