## 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 halowerk-buerowerk-email-baseline-remover-59fd89f3 -d '<json body>'
```

Example prompt: Can you remove the standard baseline boilerplate from these emails and give me back just the unique content? Here are the emails and here's the baseline template to subtract out.

## When to prefer this

Use this endpoint when you have a list of emails that share a common template, footer, header, or boilerplate baseline and you need to isolate only the unique content. Ideal for processing reply chains, templated communications, or exported email batches where a known repeated section should be subtracted out.

## Known failure modes

- Missing or malformed 'emails' field returns an error
- Missing or malformed 'baseline' field causes failure
- Payment not provided or insufficient USDC balance triggers 402 response
- Baseline not found in emails may return emails unchanged or with a warning
- Malformed JSON body returns 400-level error
