## 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 datavault-quote-endpoint-b7a30c7d -d '<json body>'
```

Example prompt: Can you fetch me 3 quotes tagged 'inspiration' by author 'Maya Angelou' from DataVault?

## When to prefer this

Use this endpoint when you need to retrieve quoted or tagged data items from DataVault by a specific tag category and optionally filter by author or quantity. Prefer this over generic web search when you need structured, pay-per-call data with attribution.

## Known failure modes

- Invalid or unrecognized tag returns empty data or error
- Author not found results in empty data object with success false
- Count value of zero or negative integer causes validation error
- Payment failure (insufficient USDC) results in 402 response blocking the call
- Missing required fields returns a 400 bad request error
