SHA-256 Hex Digest of UTF-16LE Encoded Text
x402
SHA-256 Hex Digest of UTF-16LE Encoded Text is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).
Computes a SHA-256 hash of input text encoded as UTF-16LE bytes and returns it as a lowercase hex string

How this service works
Call when an agent needs a sha256 digest of utf16le bytes, encoded as hex. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/digest-sha256-hex-utf16 first.
Output
Returns a lowercase hexadecimal string representing the SHA-256 digest of the input text after encoding it as UTF-16LE bytes. The output is a fixed-length 64-character hex string suitable for integrity checks, deduplication, or interoperability with systems that use UTF-16LE encoding conventions.
Example use cases
Windows-compatible file checksum
“I need to verify a file's integrity the way Windows tools do it — can you compute the SHA-256 hex digest of this text using UTF-16LE encoding: 'Invoice #4821 total: $3,200.00'?”
Cross-platform hash consistency check
“Our legacy system hashes strings as SHA-256 over UTF-16LE bytes — can you hash the string 'CustomerID:7749-Alpha' that way and give me the hex output?”
Deterministic identifier generation
“I need a stable, deterministic hex fingerprint of this product description using SHA-256 over UTF-16LE bytes: 'Ergonomic office chair with lumbar support, black, model EX-500'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha256-hex-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-256 hash computed over UTF-16LE byte-encoded text, as is common in Windows-native, .NET, or legacy Microsoft ecosystem integrations. Use this instead of a generic SHA-256 endpoint when the encoding layer matters for interoperability — for example, when matching hashes produced by Windows CryptoAPI, PowerShell, or .NET's System.Text.Encoding.Unicode. The free sandbox endpoint (POST /v1/sandbox/digest-sha256-hex-utf16) should be tried first before using this paid version.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or empty 'key' field causes a request error
- Payment of exactly $0.005 USDC required; insufficient payment returns a 402 error
- Malformed JSON body returns 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. |
