# RIPEMD-160 Hex Digest of UTF-16LE Bytes

> RIPEMD-160 Hex Digest of UTF-16LE Bytes is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.007/call, status unknown (last checked 2026-10-02).

Computes a RIPEMD-160 hash of text encoded as UTF-16LE bytes and returns the result as a hex string

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ripemd-160-hex-digest-of-utf-16le-bytes-0a448792 -d '<json body>'
```

Example prompt: Can you give me the RIPEMD-160 hex digest of the text 'Hello World' treated as UTF-16LE bytes? Use key 'mykey123'.

## When to prefer this

Choose this endpoint when you specifically need a RIPEMD-160 hash of text interpreted as UTF-16LE bytes (common in Windows/.NET environments or Bitcoin-related workflows) and require hex output. Use the free sandbox variant (/v1/sandbox/digest-ripemd160-hex-utf16) first to avoid costs. Prefer alternatives if you need a different hash algorithm (MD5, BLAKE2s), a different encoding (base64, base32), or a different byte encoding (latin1, UTF-8).

## Known failure modes

- Empty or missing text field returns validation error
- Text exceeding 100,000 characters is rejected
- Missing or empty key field is rejected
- Payment failure (insufficient USDC) returns 402 error
- Malformed JSON body causes 400 error

## How this service works

Call when an agent needs a ripemd160 digest of utf16le bytes, encoded as hex. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/digest-ripemd160-hex-utf16 first.

## Output

A hex-encoded RIPEMD-160 digest string computed from the input text treated as UTF-16LE bytes. The response provides the fixed-length 40-character hex hash.
