## 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-flow-api-f8945728
```

Example prompt: Pull the latest options flow data for IWM — I want to see what large trades and unusual activity are happening right now.

## When to prefer this

Choose this endpoint when you need pay-per-call options flow data without a subscription, want crypto micropayment billing via USDC on Base, or are building an agent that needs to query options activity on demand for arbitrary tickers. Prefer alternatives if you need bulk historical options data, a well-documented response schema, or SLA guarantees beyond what a Render-hosted service provides.

## Known failure modes

- 402 Payment Required — payment not sent or API key not provided
- Invalid or unrecognized ticker symbol — may return empty results or error
- Ticker not covered — not all equities may have options flow data
- Network timeout on Render.com hosted service — cold start latency possible
- Rate limiting if too many calls made without sufficient payment

## 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 options flow data for the requested equity ticker, likely including recent large trades, call/put activity, contract details (strike, expiry, size, premium), and unusual order flow signals. Exact schema is not fully documented but follows the platform's financial data format.
