## 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`):

```

Example prompt: Search our spring sale marketing campaign document for exact occurrences of the terms 'discount', 'limited offer', and 'free shipping' and give me a literal index of where each appears.

## When to prefer this

Choose this endpoint when you need exact, literal (verbatim) term matching and indexing within marketing campaign content — not semantic or fuzzy search. Ideal for compliance audits, brand consistency checks, or SEO keyword density analysis where exact string presence matters. Prefer over general semantic search endpoints when the precise literal vocabulary is what you need to track.

## Known failure modes

- Missing or empty campaign text input returns an error or empty index
- Non-literal/fuzzy search terms not supported — only exact string matches returned
- Payment failure via x402 results in 402 response and no index returned
- Unsupported document format or encoding may cause parsing errors
- Very large campaign documents may time out or require chunking
