## 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 agents-x402stock-xyz-x402stock-daily-short-sale-volume-83e13892
```

Example prompt: Pull the last 30 days of daily short-sale volume for TSLA — I want to see the short-volume ratio and how it breaks down across NYSE and Nasdaq.

## When to prefer this

Choose this endpoint when you need higher-frequency shorting pressure data than bi-weekly FINRA short interest reports — this provides daily granularity with per-venue detail. Prefer it over short interest endpoints when you need to detect intraday or day-over-day shifts in short-volume ratio, or when venue-level (NYSE vs Nasdaq vs ADF) breakdown is important for analysis. It is particularly useful for monitoring meme stocks, momentum plays, or any situation where short-selling dynamics change rapidly.

## Known failure modes

- Invalid or unknown ticker returns empty data or error response
- Limit parameter outside 1–100 range is rejected
- Data may lag by one trading day; real-time intraday figures not available
- Non-US-listed tickers (OTC, foreign listings) may return null or no data
- Payment failure via x402/USDC results in 402 response before data is returned

## How this service works

Returns daily short-sale volume and short-volume ratio for a stock.
