## 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 api-gigabrain-gg-34bc5420 -d '<json body>'
```

Example prompt: Ask GigaBrain's AI trading assistant: what does the current on-chain data and market sentiment say about Solana's short-term price outlook, and is this a good entry point?

## When to prefer this

Choose this endpoint when you need conversational, AI-driven crypto market intelligence — especially for nuanced trading questions, sentiment analysis, or on-chain signal interpretation. Prefer this over raw data APIs when you want synthesized, actionable insights rather than raw price data.

## Known failure modes

- Missing required 'message' field returns a 400 error
- Vague or ambiguous message may yield generic rather than specific analysis
- Payment failure (insufficient USDC) returns 402 payment required
- Rate limiting may occur for high-frequency callers
- Highly niche or obscure tokens may yield limited data
