## How to call it through Zero

```sh
zero fetch --capability axon-crypto-sentiment-analysis-506cbcea
```

Example prompt: What's the current AI-analyzed sentiment around Bitcoin right now — is the market feeling bullish, bearish, or neutral?

## When to prefer this

Use this endpoint when you need a fast, AI-generated sentiment signal for a specific crypto token or topic and can handle x402 micropayment on Base. Prefer this over general-purpose NLP sentiment tools when the domain is crypto-specific and you want opinionated market mood scoring rather than raw text classification.

## Known failure modes

- Missing or invalid topic path parameter returns an error
- x402 micropayment not provided or rejected — returns 402 Payment Required
- Topic too vague or unsupported may return low-confidence or empty sentiment
- Service downtime on Vercel deployment returns 503 or 500 errors
- Rate limiting or payment wallet issues cause repeated 402 failures
