## 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 royal-feel-ftc-compliance-copy-linter-127e8ad2 -d '<json body>'
```

Example prompt: Can you run an FTC compliance lint check on this batch of supplement product descriptions and flag any disease treatment claims, unqualified efficacy statements, or weight loss hype?

## When to prefer this

Use this endpoint when you need automated, rule-based FTC compliance screening of wellness or marketing copy in batch, particularly when you need specific rule IDs and severity classifications (block vs warn) rather than general editorial feedback. Ideal for pre-publication audits of supplement, weight loss, or health product advertising where FTC enforcement risk is a concern.

## Known failure modes

- Missing or malformed 'input' body returns a validation error
- Non-POST method returns 405
- Payment not included or insufficient USDC triggers 402 payment required
- Empty body array may return empty results array
- Copy exceeding size limits may be rejected

## How this service works

Pay $2.00 USDC, get an FTC compliance lint report on your wellness or marketing copy. Flags unqualified efficacy claims, disease treatment claims, weight loss hype, and unscientific buzzwords.

## Output

A JSON object with an 'ok' boolean and a 'results' array. Each result corresponds to one submitted copy item and includes its index, an 'ok' status, and a 'findings' array listing any violations — each finding has the flagged term, a rule ID (e.g. FTC-DISEASE), and a severity level (e.g. 'block').
