## When to prefer this

Choose this endpoint when you need options flow, chain, or unusual activity data for a specific stock ticker and are operating in an x402 pay-per-call environment. Ideal for agents that need on-demand, single-call options intelligence without a subscription, paying only $0.05 USDC per query. Best suited for trading agents, research bots, or decision-support systems that need real-time options market signals.

## Known failure modes

- Missing or invalid ticker symbol returns an error or empty result
- Payment not accepted results in 402 response without data delivery
- Invalid or unsupported symbol may return no data
- Network or service downtime returns a 5xx error
- Malformed query parameters may result in a 400 bad request

## How this service works

Pay-per-call APIs and a read-only provider check for x402 buyers. Inspect evidence and live terms before a caller-controlled payment; accept delivery with proof.

## Output

A JSON object containing route-specific options flow and chain data for the queried ticker symbol, returned after successful x402 micropayment acceptance. The exact schema is live and route-specific; the response includes the SML Options Flow product data for the requested symbol.
