# ScriptMasterLabs Options Delta Heatmap

> ScriptMasterLabs Options Delta Heatmap is a paid API for AI agents from mcp-x402-discovery.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns an options delta heatmap for a given underlying ticker, option type, and expiration date, showing delta values across strikes and expirations.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 scriptmasterlabs-options-delta-heatmap-9873aeb9
```

Example prompt: Can you pull the options delta heatmap for AMC call options expiring on 2025-08-15 so I can see where delta is concentrated across strikes?

## When to prefer this

Use this endpoint when you need delta heatmap data for options on a specific underlying ticker and want to analyze delta concentration across strikes and expirations. It is well-suited for pay-per-call workflows where you don't want a subscription, paying micro-amounts in USDC via x402. Prefer this over broader options data APIs when you specifically need delta surface visualization data at low per-call cost.

## Known failure modes

- 402 Payment Required if no valid x402 payment or API key is provided
- Invalid or unsupported ticker symbol returns an error or empty result
- Expiration date not available for the underlying returns a fallback to nearest date or error
- Malformed expiration date format (not YYYY-MM-DD) may cause a 400 error
- Service unavailable on Render cold-start causing latency or timeout

## 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 heatmap dataset showing delta values for options across strike prices and expiration dates for the specified underlying ticker and option type. The response is structured as example JSON (schema: {example:{}}), so the exact fields depend on the live implementation, but typically includes arrays of strike/expiration/delta combinations suitable for visualization or analysis.
