# SHA3-384 Base32 Digest

> SHA3-384 Base32 Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-01).

Computes a SHA3-384 cryptographic hash of input text and returns it encoded as a Base32 string

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-base32-digest-922488f4 -d '<json body>'
```

Example prompt: Can you compute the SHA3-384 hash of the text 'Hello, World! This is my document content.' and give me the result encoded in base32?

## When to prefer this

Choose this endpoint when you specifically need a SHA3-384 hash (not SHA-256, SHA-512, or MD5) with Base32 output encoding (not hex, base64, or base64url). It is ideal for systems requiring URL-safe or case-insensitive hash representations in the SHA3 family. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha3-384-base32) for testing before using this paid version.

## Known failure modes

- Text exceeds 100,000 character limit — request rejected with validation error
- Text or key field is empty or missing — returns 400 bad request
- Key field exceeds 512 character limit — returns validation error
- Malformed JSON body — returns parse error
- Payment of $0.01 USDC not provided — returns 402 Payment Required

## How this service works

Call when an agent needs a sha3-384 digest of text, encoded as base32. No network and no LLM. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-384-base32 first.

## Output

Returns a base32-encoded string representing the SHA3-384 hash of the input text. The digest is a fixed-length, deterministic output computed locally without any network calls or LLM inference, ensuring consistency and privacy.
