## 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 gapup-content-enrichment-media-tag-enrichment-f46d7d09 -d '<json body>'
```

Example prompt: Can you pull the genre, theme, mood, and audience tags for The Dark Knight from the content catalog — use the work entity 'film-the-dark-knight-collection:the-dark-knight'?

## When to prefer this

Use this endpoint when you need structured, fine-grained descriptive metadata (genre, theme, mood, audience) for a specific media work or franchise already indexed in the Gapup content catalog. It is preferable over generic NLP classifiers when you have a catalog entity ID and need consistent, curated tag vocabularies aligned with the Gapup media layer. Use the async mode for large or complex entities to avoid timeouts.

## Known failure modes

- Invalid or unknown entity_id returns an error or empty tag set
- Unsupported entity_type value causes a validation error
- Entity exists in catalog but has insufficient data for enrichment, returning partial tags
- Network or service timeout when not using async mode, especially for large franchises
- Payment failure via x402 protocol prevents call from completing
