## 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 limitguard-reputation-history-1d95138c
```

Example prompt: Can you pull up the full reputation score history for entity hash 'abc123xyz' on LimitGuard so I can see how their trust score has changed over the past few months?

## When to prefer this

Use this endpoint when you need historical reputation trend data for an entity rather than just its current score — ideal for due diligence workflows, counterparty risk auditing, monitoring reputation drift over time, or detecting sudden trust score drops that may indicate newly flagged risk. Prefer this over a point-in-time score endpoint when longitudinal analysis or compliance documentation is required.

## Known failure modes

- Invalid or unknown entity_hash returns empty history or 404 error
- Malformed entity_hash format causes request validation failure
- Insufficient prepaid balance results in 402 Payment Required response
- Entity with no history yet returns empty history array
- Rate limiting or quota exceeded returns 429 error

## Output

Returns a chronological array of date-and-score pairs representing the entity's trust score at each recorded point in time (e.g. [{date: '2026-01-15', score: 85}, {date: '2026-02-15', score: 92}]), allowing trend analysis and historical auditing of reputation.
