## 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 x402stock-short-sale-volume-74ece0d4
```

Example prompt: Pull the last 30 days of daily short-sale volume for GME — I want to see the short-volume ratio and the NYSE vs Nasdaq vs ADF venue breakdown to gauge shorting pressure.

## When to prefer this

Choose this endpoint when you need higher-frequency short-selling signals than bi-weekly FINRA short interest reports — specifically for daily tracking of short-volume ratio trends, venue-level short flow routing, or exempt vs non-exempt short volume breakdowns for US equities and ETFs. Prefer this over short-interest endpoints when recency matters (e.g., monitoring intraday or day-over-day changes in shorting pressure).

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty dataset
- Limit parameter outside valid range (must be 1–100) returns a validation error
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- Ticker for a non-US-listed security may return no data
- Data may not be available for the current trading day until after market close and reporting delay

## How this service works

Daily short-sale volume for a US-listed stock: total volume, short volume, exempt and non-exempt short volume, the short-volume ratio, and a per-venue breakdown (NYSE, Nasdaq, ADF), most recent day first. A higher-frequency read on shorting pressure than bi-weekly short interest. Tune with `?limit=` (default 20). From x402stock, a market & economic data API (x402, USDC).

## Output

A time-series array of daily records, most recent first, each containing: trading date, total volume, total short volume, exempt short volume, non-exempt short volume, short-volume ratio (short vol / total vol), and a breakdown of short volume by venue (NYSE, Nasdaq, ADF). Default returns up to 20 days; tunable via ?limit= (max 100).
