# SHA3-224 Base32 UTF-16LE Digest

> SHA3-224 Base32 UTF-16LE Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-24).

Computes a SHA3-224 cryptographic hash of UTF-16LE encoded text and returns the digest as a Base32 string

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 sha3-224-base32-utf-16le-digest-bfd83a32 -d '<json body>'
```

Example prompt: Compute the SHA3-224 hash of the UTF-16LE bytes of the text 'Hello, world!' and return the result as a Base32-encoded string.

## When to prefer this

Use this endpoint when you specifically need a SHA3-224 hash computed over UTF-16LE byte encoding of text, with the output represented in Base32 format. Choose this over generic SHA-256 or MD5 endpoints when the SHA3 family is required for compliance or security reasons, and when Base32 output is needed (e.g. for case-insensitive storage or display). The description recommends trying the free sandbox endpoint at /v1/sandbox/digest-sha3-224-base32-utf16 first before paying $0.004 USDC per call.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or empty 'key' field causes request rejection
- Network or payment failure (HTTP 402) if USDC payment is not properly attached
- Malformed request body returns a 400 Bad Request

## How this service works

Call when an agent needs a sha3-224 digest of utf16le bytes, encoded as base32. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-224-base32-utf16 first.

## Output

A Base32-encoded SHA3-224 hash digest of the input text after it has been encoded as UTF-16LE bytes. The result is a fixed-length Base32 string suitable for use as a checksum, fingerprint, or unique identifier.
