## 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 starchild-relay-options-tickers-reference-fac3a421 -d '<json body>'
```

Example prompt: Can you pull the list of available options tickers for SPY from the Starchild Relay — just return the first 20 results?

## When to prefer this

Use this endpoint when you need a reference list of available options tickers, particularly equity options (e.g. SPY, QQQ), and want to discover or enumerate contract identifiers before querying pricing or Greeks data. Prefer this over raw Polygon.io access when using the x402 micropayment model without a full API subscription.

## Known failure modes

- 402 Payment Required if X-PAYMENT header is missing or invalid — returns payment challenge instructions
- Empty result set if ticker symbol does not match any known contracts
- Malformed ticker string returns no results or an error
- Rate limiting or upstream provider unavailability may return 5xx errors
- Invalid limit parameter type may cause a 400 Bad Request

## How this service works

All-in-one reputable data source for AI agents and developers. Crypto spot/OHLC, derivatives funding rates, open interest, liquidations, forex, commodities, indices, social sentiment, DeFi protocols, and more — 17+ upstream data sources behind a single x402 paywall.

Usage: Send requests to any proxied path (e.g. GET /coingecko/api/v3/...). Unauthenticated requests receive a 402 challenge with payment instructions. Include X-PAYMENT header with a valid signature to access data.

## Output

A list of options ticker objects matching the query, including ticker identifiers (e.g. O:SPY...) and associated contract reference metadata, filtered by the requested symbol and limited to the specified count.
