Profit Factor Calculator
x402
Profit Factor Calculator is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Computes profit factor (gross wins divided by gross losses) from a list of PnL values using local deterministic math.

How this service works
Profit factor = gross wins / gross losses. Call when quality filters on strategy tapes before promotion. Returns profit factor as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a deterministic JSON object containing the computed profit factor (gross wins divided by gross losses), calculated purely from the supplied PnL array using local math — no external data sources involved.
Example use cases
Strategy promotion quality gate
“Before I promote this algo to live trading, calculate the profit factor from these PnL readings: [310, -95, 420, -110, 185, -70, 260, -88]. I want to make sure it clears a minimum threshold.”
Comparing two strategy tapes
“I have two strategy tapes I want to evaluate. First one has PnLs [100, -40, 80, -25, 150, -55] and the second has [200, -180, 90, -85, 110, -100]. Can you get the profit factor for each so I can compare them?”
Backtested trade series review
“I just finished a backtest and here are all my trade PnLs: [50, -20, 75, -15, 30, -40, 90, -10, 60, -35]. What's the profit factor on this series?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/profit-factorWhen to prefer
Use this endpoint when you need a fast, cheap, deterministic profit factor calculation from a list of PnL values with no API keys, no external market data, and no side effects — ideal as a quality gate before promoting a strategy to production. Prefer this over general-purpose computation when you want a single-purpose, auditable ratio with a known $0.001 cost per call.
Side effects
- Empty or missing pnls array — cannot compute ratio with no data
- All losses and no wins (gross wins = 0) — profit factor is undefined or zero, may return null or error
- All wins and no losses (gross losses = 0) — profit factor is infinite, may return null or special value
- Malformed input (non-numeric values in array) — validation error returned
- Payment failure via x402 — request rejected before computation
