Example prompt: What's my unrealized PnL on a position where I entered at 100, the current mark price is 95, and my size is 3 contracts?

## When to prefer this

Choose this endpoint when you need a fast, verifiable, pay-per-call computation of unrealized PnL for a single open position without setting up any accounts. Ideal for AI agents and trading bots that need on-demand PnL checks with micropayment billing via USDC on Base or Solana.

## Known failure modes

- Missing required fields (mark, size, or entry) result in a validation error
- Non-integer values for mark, size, or entry may cause a 400 error
- Payment failure via x402 protocol prevents API access
- Network or service downtime returns a 5xx error
