# SHA3-384 Digest (Base64, Latin-1) – agentshelf.syntexa.ch

> SHA3-384 Digest (Base64, Latin-1) – agentshelf.syntexa.ch is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).

Computes a SHA3-384 cryptographic hash of Latin-1 encoded text and returns the digest encoded as Base64.

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-base64-latin-1-agentshelf-syntexa-ch-53f65d41 -d '<json body>'
```

Example prompt: Can you compute the SHA3-384 hash of this Latin-1 text and give me the result as a Base64 string? The text is: 'Héllo wörld, this is a tëst document.'

## When to prefer this

Choose this endpoint when you specifically need a SHA3-384 (not SHA-256, SHA-512, or MD5) digest of Latin-1 encoded text returned in Base64 format. It is the right choice when working with legacy Latin-1 data pipelines, ISO-8859-1 documents, or systems that require SHA3-384 for compliance. If you need the same operation without payment, try the sandbox endpoint first. Prefer alternatives if you need a different hash algorithm, character encoding (e.g. UTF-8), or output format (e.g. hex).

## Known failure modes

- Text contains characters outside the Latin-1 (ISO-8859-1) range, causing encoding errors
- Input text is empty or exceeds 100,000 character limit, returning a validation error
- Key field is missing or exceeds 512 characters, causing a 400 bad request
- Payment of $0.003 USDC not provided or invalid, resulting in a 402 Payment Required response
- Malformed JSON body returns a 400 parse error

## How this service works

Call when an agent needs a sha3-384 digest of latin1 bytes, encoded as base64. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-384-base64-latin1 first.

## Output

Returns a Base64-encoded string representing the SHA3-384 cryptographic digest of the provided Latin-1 text input. No network calls are made; computation is purely local to the service.
