SHA3-512 Digest of Hex Bytes Encoded as Base64URL
x402
SHA3-512 Digest of Hex Bytes Encoded as Base64URL 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 SHA3-512 cryptographic hash of raw hex-encoded bytes and returns the digest encoded as base64url.

How this service works
Call when an agent needs a sha3-512 digest of hex bytes, encoded as base64url. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-512-base64url-rawhex first.
Output
A SHA3-512 cryptographic digest of the input interpreted as raw hex bytes, returned as a base64url-encoded string. The response is deterministic: the same hex input always produces the same base64url digest.
Example use cases
Integrity fingerprint for binary payload
“I have a binary blob represented as hex — '89504e470d0a1a0a' — can you compute its SHA3-512 digest encoded as base64url so I can store it as an integrity fingerprint?”
Cryptographic commitment for hex data
“I need a SHA3-512 base64url digest of the hex string 'deadbeefcafe0123' to use as a cryptographic commitment in my protocol — can you generate that?”
Hash verification of decoded hex content
“Take these hex bytes '48656c6c6f576f726c64' and compute the SHA3-512 hash encoded in base64url format so I can verify it matches the expected checksum.”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-512-base64url-rawhex?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need a SHA3-512 (not SHA-256 or SHA3-256) digest of raw binary data expressed as hex bytes, and the output must be base64url-encoded. Prefer the free sandbox endpoint POST /v1/sandbox/digest-sha3-512-base64url-rawhex first to validate your integration before spending $0.009 USDC per call on this paid version.
Side effects
- Invalid or non-hex characters in input string cause a 400 error
- Input text or key exceeds maxLength of 100,000 or 512 characters respectively causing a validation error
- Payment of $0.009 USDC not provided or fails causing a 402 Payment Required response
- Empty input (minLength violation) returns a 400 validation error
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. |
