# Quoted-Printable Decode

> Quoted-Printable Decode is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-02).

## 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-decode-9ef1ad50 -d '<json body>'
```

Example prompt: Can you decode this quoted-printable encoded string for me? It looks like: 'Subject: =?UTF-8?Q?Hello=2C=20World=21?=' — I need the plain readable text.

## When to prefer this

Use this endpoint when you have a quoted-printable encoded string (e.g. from a raw MIME email body or header) and need it decoded to plain text. It requires no internet access and no LLM, making it fast, deterministic, and cheap at $0.006 USDC. If a free sandbox endpoint at POST /v1/sandbox/quoted-printable-decode is available, prefer that first.

## Known failure modes

- Invalid or malformed quoted-printable sequences may produce garbled output or an error
- Input text exceeding 100,000 characters will be rejected
- Empty input string is rejected (minLength: 1)
- Non-quoted-printable input passed as-is or returned with an error

## How this service works

Call when an agent needs text decoded with quoted-printable. No network and no LLM. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/quoted-printable-decode first.

## Output

Returns the decoded plain text with quoted-printable encoding removed — special characters unescaped, soft line breaks resolved, and encoded sequences converted to their literal byte values.
