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 schema identifier ('delx/util-realized-pnl-fifo/v1'), the close_size used in the calculation, and the computed realized_pnl value representing the profit or loss realized on the closed portion of the position.

Example use cases

Algorithmic trading PnL tracking

“My bot just closed 5 contracts on a futures position — entry was 200, exit is 215. What's the realized PnL using FIFO accounting?”

Crypto derivatives portfolio reconciliation

“I need to reconcile my realized gains: I entered a position at 50000, closed it at 52500, and the close size was 3 units. Compute the FIFO realized PnL for me.”

Partial position close accounting

“I partially closed my trade today — entry price 300, exit price 290, close size 10. Can you calculate the realized profit or loss on that close using FIFO?”

When to prefer

Choose this endpoint when you need a fast, pay-per-use, no-signup computation of realized PnL using FIFO accounting, especially in agentic or automated trading workflows where USDC micropayment settlement via x402 on Base or Solana is acceptable. Prefer this over building custom PnL logic when you need verifiable, deterministic results at $0.001 per call.

Side effects

Missing required fields (entry, exit, or close_size) returns an error
Non-integer values for price or size fields may cause validation failure
Payment failure via x402 protocol results in 402 response and no computation
Negative or zero close_size may produce unexpected results
