## 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 100btc-radar-crypto-narrative-sentiment-scanner-66f23432 -d '<json body>'
```

Example prompt: Search the crypto radar for narratives about 'AI agents' and return the top 5 results — I want to see the sentiment, hype score, and how fast each topic is moving in the last 24 hours.

## When to prefer this

Choose this endpoint when you need real-time crypto narrative sentiment and hype velocity for a specific keyword — particularly useful for AI agent commerce, DeFi, or emerging on-chain topics. Prefer over generic sentiment APIs when you need hype scoring and 24h velocity together in one call, and when you are willing to pay per call via x402 micropayment.

## Known failure modes

- Query string too vague returns low-relevance or empty narrative list
- Payment not attached or invalid x402 v2 header results in HTTP 402 rejection
- Limit integer too high may be capped or slow to return
- Network unreachable on Tailscale VPS address if caller is not on permitted network
- Malformed JSON body returns 400 or similar client error
