# SHA-512 Base32 UTF-16LE Digest

> SHA-512 Base32 UTF-16LE Digest 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 SHA-512 cryptographic hash of text encoded as UTF-16LE bytes, returning the digest in Base32 encoding.

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 sha-512-base32-utf-16le-digest-ba65325c -d '<json body>'
```

Example prompt: Can you compute the SHA-512 hash of the text 'Hello, World!' using UTF-16LE encoding and give me the result in Base32 format?

## When to prefer this

Use this endpoint when you need a SHA-512 hash specifically computed over UTF-16LE byte representation of text (common for Windows/Microsoft ecosystem compatibility) and require Base32 output encoding. Prefer the free sandbox variant (/v1/sandbox/digest-sha512-base32-utf16) for testing. Choose SHA-256 variants if a 256-bit digest is sufficient. Choose other encoding variants (hex, base64) if Base32 is not required by your downstream system.

## Known failure modes

- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters rejected with input length error
- Missing or empty 'key' field returns a validation error
- Key exceeding 512 characters rejected
- Insufficient USDC balance results in payment failure (x402)
- Malformed JSON body returns a parse error

## How this service works

Call when an agent needs a sha512 digest of utf16le bytes, encoded as base32. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-base32-utf16 first.

## Output

Returns a Base32-encoded string representing the SHA-512 hash of the input text after it has been encoded as UTF-16LE bytes. The digest is deterministic: the same input always produces the same output.
