How this service works
Percent profit/loss from entry and exit prices. Call when ranking trades or alerts by return instead of absolute dollars. Returns pnl percent from entry→exit 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 percent profit or loss calculated from the entry and exit price inputs, with no external data sources or state involved.
Example use cases
Rank alerts by percent return
“I have a list of trade alerts — can you compute the percent PnL for each one so I can rank them by return instead of raw dollar gain? Entry was 200, exit was 215.”
Evaluate closed position performance
“I closed a position I entered at 4500 and exited at 4250 — what's my percent loss on that trade?”
Screen trades by threshold return
“I want to filter out trades that didn't hit at least 5% gain. Can you calculate the percent PnL for a trade with entry 1000 and exit 1048 so I can check if it qualifies?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/pnl-pctWhen to prefer
Use this endpoint when you need a fast, cheap, deterministic percent PnL calculation with no API keys, no market data feed, and no external dependencies — especially when ranking or filtering trades by return rather than absolute dollar value. Prefer this over building custom math in an agent when you want a reliable JSON result via x402 micropayment on Base.
Side effects
- Missing entry or exit field returns a validation error
- Non-numeric or non-integer values may cause a 400 bad request
- Entry price of zero causes a division-by-zero error
- Payment not attached or insufficient USDC results in a 402 Payment Required response
