## 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 options-chain-data-financial-data-x402-3aa6ae92
```

Example prompt: Pull the full options chain for AAPL — I want to see all the calls and puts, implied volatility, open interest, and the put/call volume ratio for the nearest expiration.

## When to prefer this

Choose this endpoint when you need structured, contract-level options chain data — including implied volatility, open interest, and put/call ratios — without setting up an API key or subscription. Ideal for agents that pay per-call in USDC via x402, need derivatives data alongside other financial data from the same provider, or require a lightweight pay-as-you-go model for occasional options lookups rather than a brokerage API integration.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty chain
- Payment not received or x402 handshake fails — returns HTTP 402 requiring USDC payment
- No options data available for the requested expiration (e.g. non-standard expiry) returns empty arrays
- Market closed or data provider outage may return stale or unavailable data
- Rate limiting or upstream Yahoo Finance throttling may cause transient failures

## How this service works

Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.

## Output

Returns a JSON object with two arrays — 'calls' and 'puts' — each containing contract-level data: contract symbol, strike, bid, ask, last price, volume, open interest, implied volatility, percent change, in-the-money flag, and last trade date. Also includes the ticker, as-of date, the expiration date queried, a list of all available expirations, and the aggregate put/call volume ratio.
