SHA3-256 / Base32 / UTF-16LE Digest
x402
SHA3-256 / Base32 / UTF-16LE Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-02).
Computes a SHA3-256 hash of UTF-16LE encoded text and returns the result as a Base32 string

How this service works
Call when an agent needs a sha3-256 digest of utf16le bytes, encoded as base32. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-256-base32-utf16 first.
Output
Returns a Base32-encoded string representing the SHA3-256 digest of the input text treated as UTF-16LE bytes. The output is a fixed-length uppercase Base32 string suitable for use as a checksum, fingerprint, or unique identifier.
Example use cases
Content integrity fingerprinting
“I need a SHA3-256 Base32 fingerprint of this document content encoded as UTF-16LE bytes — here's the text: 'Annual report Q4 2024 revenue: $4.2M'. Can you compute that digest for me?”
Deterministic ID generation from user input
“Take this username 'alice_wonder_42' and hash it using SHA3-256 over UTF-16LE bytes, returning the Base32 result so I can use it as a deterministic unique identifier.”
Cross-platform hash verification
“My system generated a SHA3-256 Base32 hash of UTF-16LE encoded text for the string 'invoice-2024-00987'. Can you compute the same hash so I can verify they match?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-256-base32-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need the SHA3-256 algorithm (not SHA2/SHA512) applied to text encoded as UTF-16LE bytes (common in Windows and .NET ecosystems) with output in Base32 format (case-insensitive, alphanumeric, no padding ambiguity). Prefer the free sandbox endpoint (/v1/sandbox/digest-sha3-256-base32-utf16) first; use this paid endpoint when the sandbox is unavailable or rate-limited.
Side effects
- Empty or missing text input returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or empty key field causes a request error
- Invalid USDC payment or insufficient funds results in a 402 Payment Required
- Network timeouts on large inputs near the character limit
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. |
