SHA-1 Hex Digest of UTF-16LE Encoded Text
x402
SHA-1 Hex Digest of UTF-16LE Encoded Text is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).
Computes a SHA-1 hash of the UTF-16LE byte representation of a given text string and returns the result as a lowercase hexadecimal string.

How this service works
Call when an agent needs a sha1 digest of utf16le bytes, encoded as hex. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/digest-sha1-hex-utf16 first.
Output
Returns a lowercase hexadecimal string representing the SHA-1 hash computed over the UTF-16LE byte encoding of the input text. The hex digest is 40 characters long (160 bits).
Example use cases
Checksum for Windows-encoded file
“I have a string that will be saved as a UTF-16LE file on Windows — can you give me the SHA-1 hex digest of 'Invoice #4821 - Total: $1,250.00' so I can verify integrity later?”
Cross-platform hash comparison
“I need to compare a SHA-1 hash generated by a .NET app that uses UTF-16LE encoding. Can you compute the SHA-1 hex digest of 'user:admin password:secret123' in UTF-16LE so I can check if they match?”
Data deduplication fingerprint
“Generate a SHA-1 hex fingerprint of this product description in UTF-16LE encoding: 'Wireless Bluetooth Headphones, Model XR-200, noise-cancelling, 30hr battery.'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha1-hex-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-1 hash computed over UTF-16LE byte encoding — common in Windows/.NET environments, legacy Microsoft applications, or when interoperating with systems that default to UTF-16LE. Prefer the free sandbox endpoint at POST /v1/sandbox/digest-sha1-hex-utf16 first; use this paid endpoint only when the sandbox is unavailable or rate-limited. If you need SHA-1 over UTF-8 or other encodings, or a different hash algorithm like MD5, BLAKE2b, or RIPEMD-160, use the corresponding sibling endpoints.
Side effects
- Empty or missing text field returns validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid key parameter may result in authentication failure
- Payment of exactly $0.003 USDC required; insufficient funds result in 402 error
- Network timeout if the service is temporarily unavailable
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. |
