## 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 web3-sentiment-mcp-27e312da -d '<json body>'
```

Example prompt: Can you analyze the sentiment of this crypto tweet: 'ETH layer-2 adoption is exploding, the ecosystem is thriving and fees are finally manageable' — tell me if it's bullish, bearish, or neutral?

## When to prefer this

Choose this endpoint when you specifically need sentiment analysis tuned for Web3, crypto, DeFi, NFT, or blockchain-related language — standard sentiment APIs may miss domain-specific jargon like 'rug pull', 'WAGMI', 'bearish divergence', or 'tokenomics'. Ideal for agents monitoring crypto social feeds, evaluating governance proposals, or tracking community mood around on-chain projects.

## Known failure modes

- Empty or missing 'data' field returns a validation error
- Non-web3 or unrelated text may yield low-confidence or generic results
- Payment failure (402) if x402 payment header is missing or insufficient
- Rate limiting if too many requests are made in a short window
- Ambiguous or very short text may produce uncertain sentiment output

## How this service works
