SHA3-384 Hex-to-Base64URL Digest
x402
SHA3-384 Hex-to-Base64URL Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.007/call, status unknown (last checked 2026-10-02).
Computes a SHA3-384 cryptographic hash of raw hex-encoded bytes and returns the result encoded as base64url

How this service works
Call when an agent needs a sha3-384 digest of hex bytes, encoded as base64url. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-384-base64url-rawhex first.
Output
Returns a SHA3-384 cryptographic digest of the provided raw hex bytes, encoded as a base64url string. The response is a compact, URL-safe representation of the 384-bit hash suitable for use in APIs, tokens, or integrity checks.
Example use cases
Integrity fingerprint for hex payload
“I have some raw hex-encoded data '48656c6c6f576f726c64' and I need its SHA3-384 digest encoded as base64url so I can verify integrity on the other end — can you compute that?”
Keyed hash for hex content verification
“Generate a SHA3-384 base64url digest for the hex bytes 'deadbeefcafe0123' using the key 'mySecretKey' so I can use it as a tamper-evident fingerprint.”
Blockchain data checksum
“I've got a blob of hex-encoded binary data 'a1b2c3d4e5f60789' from a blockchain transaction and need a SHA3-384 hash of it in base64url format for cross-system comparison.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-384-base64url-rawhex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA3-384 hash (not SHA2, SHA3-256, or other algorithms) of raw hex-encoded bytes with the output in base64url encoding. It is ideal for blockchain, cryptographic verification, or interoperability scenarios requiring this exact combination of algorithm and encoding. If a free sandbox variant at /v1/sandbox/digest-sha3-384-base64url-rawhex is available, prefer that first to avoid the $0.007 USDC charge.
Side effects
- Invalid hex input (non-hex characters in text field) returns an error
- Input exceeds 100,000 character limit causes rejection
- Missing required fields returns validation error
- Payment not received or incorrect amount results in 402 response
- Malformed key field (exceeds 512 characters) causes rejection
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. |
