## 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 x402-facilitator-dexter-twitter-x-topic-analyzer-5737e578 -d '<json body>'
```

Example prompt: Can you analyze what people are saying on Twitter about 'AI regulation' over the last 48 hours, focusing on accounts like @elonmusk and @sama, using up to 30 tweets with at least 50 engagement, and give me a narrative summary with highlights?

## When to prefer this

Use this endpoint when you need a structured, summarized analysis of Twitter/X discourse on a specific topic, keyword set, or account group — especially when you want engagement-filtered highlights and a narrative summary rather than raw tweet data. Prefer it over generic search when you need bucketed highlights, conversation thread analysis, or multi-account focus with engagement thresholds.

## Known failure modes

- twitter_analyze_timeout – upstream Twitter data fetch timed out, ok=false with status code
- Invalid topic or empty query – no tweets found matching criteria
- Rate limiting or payment failure – x402 payment not processed, request rejected
- maxTweets out of range (must be 10-50) – validation error
- lookbackHours out of range (must be 1-168) – validation error

## How this service works

Twitter/X topic analysis with engagement metrics and highlights.

## Output

A structured JSON payload with ok=true and a result object containing a narrative summary of the topic, aggregated engagement metrics, and highlighted representative tweets bucketed by theme or relevance. On failure, ok=false with an error code (e.g. twitter_analyze_timeout) and an upstream HTTP status.
