# SHA3-384 Digest with Base32 Encoding over UTF-16LE

> SHA3-384 Digest with Base32 Encoding over UTF-16LE is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-02).

Computes a SHA3-384 cryptographic digest of input text encoded as UTF-16LE bytes, then returns the result encoded as Base32.

## 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 sha3-384-digest-with-base32-encoding-over-utf-16le-772c3b59 -d '<json body>'
```

Example prompt: Hash the text 'Hello, World!' using SHA3-384 over its UTF-16LE bytes and give me the result encoded as Base32.

## When to prefer this

Choose this endpoint when you specifically need a SHA3-384 hash computed over the UTF-16LE byte representation of text (common for Windows-native or .NET interoperability scenarios) and require the output in Base32 encoding rather than hex or Base64. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha3-384-base32-utf16) for testing; use this paid endpoint for production workloads where the sandbox is unavailable or rate-limited.

## Known failure modes

- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing 'key' field may cause a request error
- Payment of $0.008 USDC not provided results in HTTP 402
- Network timeout on the paid endpoint — caller should try the unpaid sandbox variant first

## How this service works

Call when an agent needs a sha3-384 digest of utf16le bytes, encoded as base32. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-384-base32-utf16 first.

## Output

Returns a Base32-encoded string representing the SHA3-384 cryptographic digest of the input text after encoding it as UTF-16LE bytes. The response is a deterministic, fixed-length hash string suitable for integrity checks, deduplication, or tamper-detection workflows.
