## 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 financial-author-scorecard-x-twitter-creator-track-record-8e1b6b5a -d '<json body>'
```

Example prompt: Can you pull up the scorecard for @FinanceFred on X — I want to see his hit rate, sample size, and Wilson confidence interval on his stock market calls before I follow his advice?

## When to prefer this

Use this endpoint when you need statistically grounded credibility data on a specific X/Twitter finance creator — especially when the Wilson confidence interval, directional breakdown, and claim resolution history matter. Prefer this over generic social-media analytics when the goal is investment-influencer due diligence rather than follower counts or engagement metrics.

## Known failure modes

- Handle not found or author has no tracked claims — returns empty or error response
- Insufficient resolved claims for meaningful statistics — Wilson interval may be wide or unavailable
- Rate limiting or payment failure via x402 protocol
- Author handle typo or non-X/Twitter handle submitted
- Stale data if the author has not posted recent trackable claims
