## How to call it through Zero

```sh
zero fetch --capability axon-crypto-sentiment-tracker-4009ab82

Example prompt: What's the current market sentiment around Bitcoin — is the crypto community feeling bullish or bearish right now?

## When to prefer this

Choose this endpoint when you need real-time AI-generated sentiment scoring specifically for cryptocurrency topics, tokens, or market keywords — especially when you want a quick directional signal (bullish/bearish/neutral) rather than raw social data or price feeds. It is particularly suited for pre-trade analysis, market briefings, or portfolio monitoring workflows that operate on a per-query micropayment basis via x402 on Base.

## Known failure modes

- Unknown or unsupported topic returns empty or null sentiment
- Payment not completed via x402 results in 402 Payment Required error
- Invalid or malformed topic string may return generic error
- Rate limiting may occur if micropayment is not properly processed
- Topic too broad or ambiguous may yield low-confidence sentiment
