## 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 x402donghang-crypto-radar-c47763e1
```

Example prompt: What's the current narrative and sentiment radar for SOL over the last 6 hours — give me signals, risks, and any key watch items along with the live CoinGecko price?

## When to prefer this

Choose this endpoint when you need a structured, verifiable, multi-source crypto sentiment report that combines social/web narrative signals with a live market price snapshot — especially when you need source URLs for auditability, named narratives with direction, and a confidence score. Prefer this over generic LLM-based crypto commentary when you need fresh data from the last 1h to 7d and a machine-readable JSON format suitable for downstream agent processing.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty signals
- Time window enum value outside allowed set (1h/6h/24h/7d) causes validation failure
- CoinGecko market data unavailable leads to missing market field
- Insufficient recent web/X posts for the window may result in low confidence score or sparse signals
- Payment of $0.03 USDC not completed results in 402 Payment Required response
- focus parameter exceeding 300 characters may be rejected or truncated
