## 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 quoted-printable-encoder-5e350308 -d '<json body>'
```

Example prompt: Can you encode this text using quoted-printable? Here's the content: 'Subject: Héllo Wörld — please encode it so it's safe for email transport.'

## When to prefer this

Use this endpoint when you need a deterministic, server-side quoted-printable encoding without relying on local libraries, LLMs, or external network calls. Prefer the free sandbox endpoint (/v1/sandbox/quoted-printable-encode) first; fall back to this paid endpoint when the sandbox is unavailable or rate-limited.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Payment not included or insufficient USDC results in a 402 Payment Required response
- Malformed JSON body returns a 400 error

## How this service works

Call when an agent needs text encoded with quoted-printable. No network and no LLM. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/quoted-printable-encode first.

## Output

Returns the quoted-printable encoded version of the submitted text string, with special and non-ASCII characters replaced by their '=XX' escape sequences and lines wrapped to comply with QP standards.
