SHA3-384 Digest → Base64 (from Hex Bytes)
x402
SHA3-384 Digest → Base64 (from Hex Bytes) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-02).
Computes a SHA3-384 cryptographic hash of raw hex-encoded bytes and returns the digest encoded as base64.

How this service works
Call when an agent needs a sha3-384 digest of hex bytes, encoded as base64. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-384-base64-rawhex first.
Output
Returns a base64-encoded SHA3-384 digest of the provided hex-byte input. The response is a compact, URL-safe base64 string representing the 48-byte (384-bit) hash of the raw bytes decoded from the input hex string.
Example use cases
Integrity fingerprint for binary payload
“I have a binary payload represented as hex — '4d6f636b44617461486578537472696e67' — can you compute its SHA3-384 digest and give me the result in base64 so I can use it as an integrity fingerprint?”
Cryptographic checksum for audit log
“Compute a SHA3-384 hash of these hex-encoded audit log bytes '0a1b2c3d4e5f6a7b8c9daebfcd' and return it as base64 so I can store it alongside the record.”
Verify data fingerprint before signing
“Before I sign this data block, I need its SHA3-384 hash in base64. The raw data in hex is 'cafebabe0011223344556677'. Can you compute that for me?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-384-base64-rawhex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA3-384 (not SHA-256, SHA-512, or MD5) digest of raw bytes supplied as hex and want the output in base64 encoding. It is a pure computation with no network calls and no LLM — ideal for deterministic, reproducible cryptographic fingerprinting of binary data. Use the free sandbox variant (/v1/sandbox/digest-sha3-384-base64-rawhex) first to avoid charges during development.
Side effects
- Invalid hex string (odd-length or non-hex characters) returns an error
- Exceeds maxLength of 100000 characters for the text field
- Missing required input fields returns a validation error
- Payment failure or insufficient USDC balance returns 402
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| key | string | HMAC secret. Required on HMAC SKUs. Omit it for plain digests and checksums. The key is not stored. |
| text | string | Message to digest. For raw-hex SKUs this is hex bytes; for utf16 or latin1 SKUs it is decoded with that encoding. Otherwise it is UTF-8 text. |
