## 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 x402-profanity-filter-api-388a9762 -d '<json body>'
```

Example prompt: Check this comment for profanity before I post it: 'This product is absolute garbage and the support team are complete idiots!' — flag any offensive words and tell me if it's safe to publish.

## When to prefer this

Choose this endpoint when you need lightweight, keyless, pay-per-use profanity detection without setting up API accounts or managing credentials — ideal for AI agents doing one-off content moderation checks or pipelines where per-call micropayments via x402 are acceptable.

- Payment not included or insufficient triggers 402 Payment Required response
- Unsupported language code may fall back to default or return error
