## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-option-payoff-points-calculator-9985bba3 -d '<json body>'
```

Example prompt: Calculate the payoff diagram points for a bull call spread: I bought 1 call at strike 100 paying a $2 premium and sold 1 call at strike 110 collecting a $1 premium — show me the payoff at spot prices 85, 90, 95, 100, 105, 110, 115, 120.

## When to prefer this

Use this endpoint when you need to programmatically compute option strategy payoff diagrams without requiring a subscription or API key — pay $0.001 USDC per call via x402. Ideal for AI agents building options analysis tools, computing break-even points, or rendering P&L charts for multi-leg strategies. Prefer over manual computation when multiple legs or many spot samples are involved.

## Known failure modes

- Missing or malformed legs array returns validation error
- Empty spots array results in empty points response
- Invalid leg properties (missing type, strike, qty, or premium) cause computation failure
- Payment failure via x402 if USDC balance is insufficient

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns an array of {spot, payoff} data points representing the net payoff of the option strategy at each requested spot price, suitable for rendering a payoff diagram or computing break-even levels. Schema is tagged as delx/util-option-payoff-points/v1.
