## 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 jubjub-purchase-metadata-4e1d4530 -d '<json body>'
```

Example prompt: Before I buy that JubJub content item, pull up the full structured metadata for it — I want to see the provenance score, chapter markers, entity extraction, cinematographic analysis, and what questions it answers.

## When to prefer this

Use this endpoint when you need the full suite of structured metadata for a single content item before deciding to purchase it, train on it, or publish it. This is the appropriate pre-purchase enrichment step that surfaces provenance, entity, chapter, and cinematographic data in one call. Prefer this over the premium license endpoint (which adds transcript and rights-holder info) when you do not yet need licensing details.

## Known failure modes

- Invalid or non-existent content ID returns a 404 error
- Insufficient USDC balance or payment failure results in a 402 error
- Content not yet processed returns a 202 with processing status
- Expired 24-hour cache window may trigger a fresh re-analysis charge
- Malformed request body returns a 400 validation error
