## 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 cambrian-x402-crypto-sentiment-shifts-detector-44ba319a
```

Example prompt: Check if there have been any major sentiment shifts for Solana recently — I want to know if the community mood has flipped bullish or bearish.

## When to prefer this

Use this endpoint when you need to detect discrete, significant inflection points in crypto token sentiment rather than a continuous sentiment score — ideal for triggering trading signals, alerts, or workflow automations when community mood meaningfully reverses direction.

## Known failure modes

- Invalid or unsupported token symbol returns empty results
- No recent sentiment shift detected returns empty array
- Rate limiting or payment failure returns 402 error
- Malformed query parameters may return 400 error
- Token with insufficient social data volume may not produce reliable shifts
