## 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 the-stall-earnings-reaction-data-36ed49b7
```

Example prompt: Pull the earnings reaction history for NVDA over the last 12 periods — I want to see how the stock has moved after each earnings announcement.

## When to prefer this

Choose this endpoint when you need historical post-earnings price reaction data for a specific US equity, especially for options pricing, volatility modeling, or quantitative earnings strategies. It requires no API key or account setup — just a USDC payment on Base mainnet. Prefer this over general financial data APIs when you specifically need earnings event price reaction history rather than general price history or fundamental data.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Requesting more than 16 periods returns a validation error
- Non-US equities or OTC tickers may not be supported
- Insufficient USDC balance or failed x402 payment results in a 402 response and no data
- Very recently listed stocks may have fewer historical earnings periods than requested

## How this service works

## Output

A structured dataset covering up to 16 past earnings periods for the requested ticker, including earnings announcement dates, the stock's price reaction (percentage move) around each event, and potentially beat/miss information relative to analyst expectations.
