## 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 script-master-labs-options-delta-heatmap-9d96b334
```

Example prompt: Can you pull the options delta heatmap for AMC call options expiring 2025-07-18 so I can see delta exposure across strikes?

## When to prefer this

Use this endpoint when you need delta heatmap data specifically for U.S. equity options, especially when you want to analyze delta distribution across strikes and expirations for a given underlying. It is priced at $0.001 USDC per call via x402 on Base, making it cost-effective for occasional lookups. Prefer this over general options data APIs when you specifically need delta-centric visualizations or heatmap-structured output for trading analysis.

## Known failure modes

- Invalid ticker symbol returns an error or empty dataset
- Requested expiration date not available falls back to nearest available or returns an error
- Network or payment failure via x402 protocol results in 402 Payment Required response
- Service downtime on mcp-x402.onrender.com causes connection errors
- Malformed query parameters may return validation errors or unexpected data

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

Returns a delta heatmap dataset showing delta values mapped across strike prices and expiration dates for the specified underlying ticker and option type (call or put). The response includes structured data representing how delta is distributed across the options chain, enabling visual or analytical inspection of delta exposure.
