# SHA-384 Digest of UTF-16LE Bytes Encoded as Base32

> SHA-384 Digest of UTF-16LE Bytes Encoded as Base32 is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-29).

Computes a SHA-384 hash of the UTF-16LE encoding of input text and returns the digest as a Base32-encoded string.

## 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 sha-384-digest-of-utf-16le-bytes-encoded-as-base32-4cb618d6 -d '<json body>'
```

Example prompt: Compute the SHA-384 hash of the UTF-16LE bytes of the text 'Hello, World!' and give me the result as a Base32-encoded string.

## When to prefer this

Choose this endpoint when you specifically need a SHA-384 hash (not SHA-256 or SHA-3) computed over the UTF-16LE byte encoding of a Unicode string, with the result expressed in Base32 (not hex or Base64). This is useful for interoperability with Windows-native Unicode systems or protocols that require UTF-16LE byte representation. Prefer the free sandbox variant at /v1/sandbox/digest-sha384-base32-utf16 for testing before using this paid endpoint.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Key field exceeding 512 characters is rejected
- Payment not provided or insufficient results in HTTP 402 response
- Malformed request body returns HTTP 400

## How this service works

Call when an agent needs a sha384 digest of utf16le bytes, encoded as base32. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-sha384-base32-utf16 first.

## Output

Returns a Base32-encoded string representing the SHA-384 cryptographic hash computed over the UTF-16LE byte encoding of the provided input text. The digest is deterministic and fixed-length, suitable for integrity verification, fingerprinting, or deduplication.
