## How to call it through Zero

```sh
zero fetch --capability alpha-palmvox-com-74f1aaf6
```

Example prompt: Can you pull all HIGH confidence upward trading signals on the Base chain from PalmVox Alpha's screener right now?

## When to prefer this

Use this endpoint when you need to browse and filter a set of active trading signals across multiple tokens simultaneously, rather than fetching a single best signal. Ideal when the user wants to narrow signals by confidence tier, directional bias, or specific chain before acting.

## Known failure modes

- Invalid confidence value (not HIGH/MEDIUM/LOW) may return empty results or error
- Invalid direction value may return no results
- Chain not supported returns empty token list
- Payment of $0.005 USDC not provided results in 402 Payment Required
- No signals matching the filter criteria returns empty tokens array with count 0

## How this service works

Token screener — filter active signals by confidence (HIGH/MEDIUM/LOW), direction (up/down), or chain (base). Returns matching signals with full data. Query params: confidence, direction, chain.

## Output

Returns a list of matching trading signals, each with token symbol, entry price, target price, stop loss, risk/reward ratio, confidence level, 24h volume change, signal description, source, chain, and timestamp. Also includes a count of matching results.
