## How to call it through Zero

```sh

```

## When to prefer this

Choose this endpoint when you need AI-filtered news and social media intelligence on a specific non-token crypto topic (e.g., airdrops, DeFi trends, governance, Layer 2 news) rather than token-specific price or sentiment data. It is ideal for topic-level research across crypto Twitter and news, where the subject is a theme or event rather than a specific coin or token.

## Known failure modes

- Topic exceeds 2 words — API rejects or truncates query
- No relevant news or tweets found for the topic — empty or minimal data returned
- Invalid topic format — error string in data field
- Payment failure (x402) — 402 response before content is delivered
- Rate limiting or upstream Twitter/news source unavailability
