SHA3-256 Digest of Hex Bytes Encoded as Base64
x402
SHA3-256 Digest of Hex Bytes Encoded as Base64 is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-29).
Computes a SHA3-256 cryptographic hash of hex-encoded input bytes and returns the digest encoded as base64.

How this service works
Call when an agent needs a sha3-256 digest of hex bytes, encoded as base64. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-256-base64-rawhex first.
Output
Returns a SHA3-256 cryptographic digest of the input hex bytes, encoded as a base64 string. The output is a deterministic, fixed-length hash suitable for integrity checking, fingerprinting, or use as a derived identifier.
Example use cases
Data integrity checksum for hex payload
“I'm sending a hex-encoded binary payload '4d792064617461' to a remote service and need to include a SHA3-256 checksum encoded as base64 so the receiver can verify it hasn't been tampered with. Can you compute that for me?”
Verifying cryptographic hash of binary content
“I have binary content represented as hex bytes 'deadbeefcafe0123' and I need to verify its SHA3-256 fingerprint in base64 format — can you hash those hex bytes and give me the base64 digest?”
Generating reproducible SHA3-256 token from hex seed
“I want to derive a SHA3-256 hash from a hex-encoded seed value '0a1b2c3d4e5f' and get the result as a base64 string to use as a stable identifier in my pipeline.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-256-base64-rawhex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA3-256 hash of raw bytes supplied in hexadecimal form and want the output as standard base64 (not base64url or hex). If a free unpaid sandbox version (/v1/sandbox/digest-sha3-256-base64-rawhex) is available, prefer that first. Use this paid endpoint when the sandbox is unavailable or rate-limited. Prefer sibling endpoints if a different hash algorithm (e.g. SHA3-224), encoding (e.g. base64url, hex), or input encoding (e.g. UTF-16LE) is required.
Side effects
- Invalid or non-hex input text causes a processing error
- Input exceeds 100,000 character limit returns a validation error
- Empty or missing 'text' field returns a bad request error
- Payment failure or insufficient USDC balance results in a 402 response
- Malformed JSON body causes a 400 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. |
