# SHA-384 Hex Digest of Raw Hex Bytes

> SHA-384 Hex Digest of Raw Hex Bytes is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.009/call, status unknown (last checked 2026-09-29).

Computes a SHA-384 digest of raw bytes supplied as a hex string, returning the result encoded as a hex 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 sha-384-hex-digest-of-raw-hex-bytes-532d5001 -d '<json body>'
```

Example prompt: Can you compute the SHA-384 hash of these raw bytes (given as hex): 'deadbeef0102030405' and give me the result as a hex string?

## When to prefer this

Choose this endpoint when you specifically need SHA-384 applied to raw bytes that are supplied in hexadecimal encoding, and you need the output also as hex. Use the free sandbox endpoint (POST /v1/sandbox/digest-sha384-hex-rawhex) first for testing. Prefer this over SHA-256 or SHA-512 endpoints when SHA-384 is required by your protocol or compliance requirement.

## Known failure modes

- Input 'text' is not valid hex — returns error indicating malformed hex input
- Input exceeds 100,000 character limit — request rejected
- Missing required fields ('key' or 'text') — validation error
- Payment of $0.009 USDC not provided or insufficient — 402 Payment Required
- Odd-length hex string may fail raw byte decoding

## How this service works

Call when an agent needs a sha384 digest of hex bytes, encoded as hex. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/digest-sha384-hex-rawhex first.

## Output

Returns a hex-encoded SHA-384 digest computed over the raw bytes represented by the input hex string. The output is a 96-character lowercase hex string corresponding to the 48-byte SHA-384 hash.
