## 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 stablejack-pair-derivatives-indicators-97a14eb8 -d '<json body>'

## When to prefer this

Choose this endpoint when you need pair-specific derivatives market indicators (open interest, IV, Greeks, skew, put/call ratio) rather than broader market screeners or funding rate history. Prefer this over sibling endpoints when you have a specific pair in mind and need a targeted derivatives metric rather than a cross-market comparison or screener sweep.

## Known failure modes

- Missing or unsupported operation returns an error — always include a valid operation field
- Missing required market fields (pair, asset class, etc.) causes a 400 error
- Unsupported trading pair returns empty result or not-found error
- Invalid params structure causes a schema validation failure
- Rate limit exceeded returns a payment or quota error

## How this service works

Retrieve a selected pair-level derivatives indicator. Always include a supported operation and params with the required market fields.

## Output

Returns a selected pair-level derivatives indicator value or series (e.g. open interest, implied volatility, Greeks, skew, put/call ratio, or term structure data) for the specified trading pair and market, formatted for agent consumption.
