# SHA-512/224 Digest (Base32, UTF-16LE) — agentshelf.syntexa.ch

> SHA-512/224 Digest (Base32, UTF-16LE) — agentshelf.syntexa.ch is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Computes a SHA-512/224 hash of a UTF-16LE-encoded string and returns the digest encoded as Base32.

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-512-224-digest-base32-utf-16le-agentshelf-syntexa-ch-63c1fee6 -d '<json body>'
```

Example prompt: Can you compute the SHA-512/224 hash of "Hello, world!" encoded as UTF-16LE bytes and give me the result as a Base32 string?

## When to prefer this

Choose this endpoint when you specifically need a SHA-512/224 digest (not SHA-256, SHA-512, or blake2b) computed over UTF-16LE-encoded bytes (common for Windows/COM compatibility) and want the result as Base32 (not hex or base64). Use the unpaid sandbox endpoint at /v1/sandbox/digest-sha512-224-base32-utf16 for testing before incurring the $0.01 USDC cost.

## Known failure modes

- Empty or missing text field returns validation error
- Text exceeding 100,000 characters rejected
- Missing key field causes request failure
- Payment failure (insufficient USDC balance) results in 402 response
- Malformed request body returns 400 error

## How this service works

Call when an agent needs a sha512-224 digest of utf16le bytes, encoded as base32. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-224-base32-utf16 first.

## Output

Returns a Base32-encoded string representing the SHA-512/224 hash computed over the UTF-16LE byte encoding of the input text. The digest is deterministic and consistent for any given input.
