## How to call it through Zero

```sh
zero fetch --capability gloom-equity-screener-ca21b009
```

## When to prefer this

Prefer this endpoint when you need to discover or filter equities by sector, industry, or exchange using structured screener criteria — especially within the Gloom open-source finance terminal ecosystem. It is well-suited for building investment watchlists, sector analysis, or feeding downstream portfolio tools. It charges a small per-call fee via x402/USDC, making it appropriate for on-demand, agent-driven queries rather than high-frequency bulk screening.

## Known failure modes

- Invalid or malformed screener definition query parameter returns an error
- No equities match the given filter criteria, returning an empty data array
- Missing required 'definition' query parameter causes a 400 Bad Request
- API payment failure (x402 payment not accepted) blocks the request
- Rate limiting or quota exceeded returns a 429 error

## How this service works

## Output

Returns an array of equity objects, each containing the stock symbol, company name (if available), sector, industry, exchange, and currency — suitable for building watchlists, sector analysis, or investment research pipelines.
