# SHA3-384 Digest of Latin1 Bytes, Base64url Encoded

> SHA3-384 Digest of Latin1 Bytes, Base64url Encoded is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-02).

Computes a SHA3-384 cryptographic hash of Latin1-encoded input bytes and returns the digest encoded as base64url.

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-of-latin1-bytes-base64url-encoded-6e365b1b -d '<json body>'
```

Example prompt: Can you compute the SHA3-384 hash of the Latin1-encoded text 'Hello, World!' and give me the result as a base64url string?

## When to prefer this

Choose this endpoint when you specifically need a SHA3-384 hash of Latin1-encoded bytes with base64url output encoding. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha3-384-base64url-latin1) first to validate inputs before paying. Use this over sibling endpoints when SHA3-384 is required by a protocol or standard, or when base64url encoding is needed for URL-safe transmission. Do not use if you need a different hash algorithm (MD5, BLAKE2, RIPEMD) or a different encoding (hex, base32, base64).

## Known failure modes

- Input text exceeds 100,000 character limit — request rejected
- Input key exceeds 512 character limit — request rejected
- Text contains characters not representable in Latin1 — may produce unexpected hash
- Missing required 'text' field — validation error returned
- Payment not fulfilled — 402 response, use sandbox endpoint first

## How this service works

Call when an agent needs a sha3-384 digest of latin1 bytes, encoded as base64url. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-384-base64url-latin1 first.

## Output

Returns a SHA3-384 cryptographic digest of the input text interpreted as Latin1-encoded bytes, represented as a base64url-encoded string. The output is a fixed-length, URL-safe hash suitable for checksums, fingerprinting, or integrity verification.
