## 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 mindshare-api-x-twitter-topic-sentiment-analysis-c698f58f -d '<json body>'
```

Example prompt: Can you search recent X posts about 'Bitcoin ETF' and tell me what the overall sentiment looks like — how many are positive, neutral, or negative, and what the average sentiment score is?

## When to prefer this

Choose this endpoint when you need real-time social sentiment analysis specifically from X/Twitter — not just raw tweet text but structured per-tweet sentiment scores plus an aggregate distribution. It is ideal for brand monitoring, crypto/asset social mindshare tracking, event reaction analysis, or any use case where you need a quantitative positive/neutral/negative breakdown of current public X conversation around a topic. Prefer it over generic web search when you specifically need Twitter/X data with sentiment scoring already computed.

## Known failure modes

- Topic returns no recent public tweets — empty result set
- X API rate limits or access restrictions cause partial or failed retrieval
- Ambiguous or overly broad query terms return noisy, low-relevance tweets
- Payment failure (insufficient USDC balance) prevents the call from completing
- Network timeout if X search backend is slow to respond
