## 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 syra-ai-trading-brain-natural-language-crypto-intelligence-ce06f4d8
```

Example prompt: Ask Syraa's brain: what's the current sentiment and whale activity around BTC, and is there any smart-money risk signal I should know about right now?

## When to prefer this

Use this endpoint when you need a single conversational interface to query multiple crypto intelligence streams (sentiment, whale tracking, risk, signals) simultaneously via natural language, rather than hitting multiple specialized endpoints separately. Ideal for agents that need quick, synthesized market intelligence without constructing complex multi-API workflows.

## Known failure modes

- Payment not received — returns 402 if USDC payment not attached
- Missing required 'question' query parameter — returns 400 or empty result
- Ambiguous or unsupported question type — may return vague or null data
- Rate limiting or infrastructure downtime — returns 5xx error
- Market data feed lag — real-time signals may be slightly delayed
