# SHA3-384 Digest (Base32, Latin1) — agentshelf.syntexa.ch

> SHA3-384 Digest (Base32, Latin1) — agentshelf.syntexa.ch is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-23).

Computes a SHA3-384 cryptographic hash of Latin-1 (ISO-8859-1) encoded input text and returns the digest encoded as a Base32 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 sha3-384-digest-base32-latin1-agentshelf-syntexa-ch-364d56db -d '<json body>'
```

Example prompt: Can you compute the SHA3-384 hash of the text 'Héllo Wörld' treating it as Latin-1 bytes and give me the result as a Base32 string?

## When to prefer this

Use this endpoint when you specifically need a SHA3-384 hash of text that must be interpreted as Latin-1 (ISO-8859-1) bytes rather than UTF-8, and the output must be Base32-encoded. Prefer the unpaid sandbox endpoint (/v1/sandbox/digest-sha3-384-base32-latin1) for testing. Choose this over sibling endpoints when SHA3-384 strength and Base32 output format are both required constraints.

## Known failure modes

- Text contains characters outside the Latin-1 (ISO-8859-1) range, causing encoding errors
- Input text exceeds 100,000 character limit
- Key field exceeds 512 character limit or is empty when provided
- Payment of exactly $0.009 USDC not fulfilled, resulting in HTTP 402
- Network timeout or service unavailability

## How this service works

Call when an agent needs a sha3-384 digest of latin1 bytes, encoded as base32. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-384-base32-latin1 first.

## Output

Returns a Base32-encoded SHA3-384 digest string computed from the provided text interpreted as Latin-1 (ISO-8859-1) bytes. The output is a deterministic, fixed-length hash suitable for integrity verification or fingerprinting.
