# Unicode Escape Encode

> Unicode Escape Encode is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-29).

Encodes a text string using Python-style unicode-escape encoding, returning the escaped byte representation, with no network calls or LLM involvement.

## 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 unicode-escape-encode-b1063964 -d '<json body>'
```

Example prompt: Can you unicode-escape encode this string for me: 'Hello, 世界! 🌍'?

## When to prefer this

Choose this endpoint when you need deterministic, offline unicode-escape encoding of a text string without any LLM inference or external network calls. It is ideal for encoding non-ASCII, emoji, or multilingual text into ASCII-safe escape sequences for config files, source code, or data serialization. Prefer the free sandbox POST /v1/sandbox/unicode-escape-encode endpoint first if available; use 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
- Malformed request body returns a 400 error
- Payment not attached or insufficient USDC results in 402 Payment Required

## How this service works

Call when an agent needs text encoded with unicode-escape. No network and no LLM. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/unicode-escape-encode first.

## Output

The endpoint returns the unicode-escape-encoded version of the input text string, where non-ASCII and special characters are replaced with \uXXXX or \UXXXXXXXX escape sequences, suitable for embedding in ASCII-safe contexts like config files, source code literals, or JSON.
