## 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 amazon-seller-central-restricted-keyword-linter-0634c99c
```

Example prompt: Scan this supplement listing copy for Amazon ASIN suppression triggers — category is supplements, text is 'Supports healthy blood sugar levels and fights diabetes naturally. Clinically proven to kill bacteria and boost immunity.' — and give me compliant rewrites for anything flagged.

## When to prefer this

Use this endpoint when you need pre-publication compliance screening of Amazon listing copy specifically for FDA DSHEA disease claims, EPA FIFRA pesticide language, or OTC drug flags — especially when you want actionable compliant rewrites alongside flagged terms. Prefer this over generic keyword tools when the goal is Amazon ASIN suppression prevention rather than SEO optimization or general content moderation.

## Known failure modes

- Missing required category parameter returns validation error
- Invalid category enum value (not supplements/topicals/electronics/home_goods) returns error
- Empty or missing text parameter returns results with scanned_text_present: false and no matched triggers
- Very long text inputs may be truncated or cause timeout
- Payment failure via x402 returns 402 status before processing

## How this service works

Amazon Seller Central ASIN suppression keyword linter for FDA DSHEA disease claims, EPA FIFRA pesticide triggers, and OTC drug flags. Pass ?category=supplements|topicals|electronics|home_goods (default supplements) & optional ?text=<bullet/title copy>. Returns matched trigger words, suppression cause, compliant structure/function rewrites, and TIC lab docs.

## Output

Returns a JSON object with the scanned category, whether text was provided, an array of matched trigger keywords, the risk level (e.g. high/medium/low), the policy domain (FDA DSHEA / EPA FIFRA / OTC), a suppression reason explanation, an array of compliant structure/function replacement phrases for each flagged trigger, a list of required compliance documentation (e.g. TIC lab docs), a timestamp, and a disclaimer.
