## 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 apiosk-brand-trust-check-4b9beec8 -d '<json body>'
```

Example prompt: Can you run a brand trust-check on this product page copy — 'The cheapest tool for your workflow' — and flag any forbidden words or missing required terms like 'Apiosk', and suggest fixes?

## When to prefer this

Use this endpoint when you need programmatic enforcement of brand language rules — specifically catching forbidden words/phrases and verifying required terms appear in copy — and want actionable replacement suggestions. Prefer this over generic grammar or spell-check tools when the goal is brand consistency rather than linguistic correctness.

## Known failure modes

- Missing or empty 'text' field returns validation error
- Malformed 'rules' object may cause unexpected behavior or be ignored
- Network timeout on gateway for large text payloads
- Payment failure via x402 protocol results in 402 response and no validation performed
- Ambiguous or conflicting rules may produce false positives or incomplete issue lists

## How this service works

Check copy against brand rules: forbidden words/phrases, required terms that must appear, and preferred-term substitutions. Returns issues for violations plus suggested from->to replacements.

## Output

Returns a JSON object with a boolean 'valid' flag, an array of 'issues' describing forbidden words detected or required terms missing, and a 'suggestions' array with from/to replacement pairs to bring the copy into brand compliance.
