# RIPEMD-160 Hex Digest (Latin1 Input)

> RIPEMD-160 Hex Digest (Latin1 Input) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-02).

Computes a RIPEMD-160 cryptographic hash of Latin1-encoded bytes and returns the result as a lowercase hex string.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-latin1-input-3721e28c -d '<json body>'
```

Example prompt: Can you compute the RIPEMD-160 hex digest of this Latin1-encoded text: 'Héllo wörld'?

## When to prefer this

Choose this endpoint when you specifically need a RIPEMD-160 digest (not SHA-256 or MD5) of Latin1-encoded byte input returned as a hex string — common in Bitcoin/cryptocurrency address derivation pipelines, legacy European financial systems, or any interoperability scenario mandating RIPEMD-160. Prefer the free sandbox endpoint (/v1/sandbox/digest-ripemd160-hex-latin1) first during development; use this paid endpoint for production workloads.

## Known failure modes

- Input text contains characters outside the Latin1 (ISO-8859-1) range, causing encoding errors
- Text exceeds 100,000 character limit, resulting in rejection
- Missing or empty 'text' field triggers validation error
- Key field exceeds 512 characters
- Network timeout or service unavailability
- Payment failure or insufficient USDC balance (x402 payment required)

## How this service works

Call when an agent needs a ripemd160 digest of latin1 bytes, encoded as hex. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/digest-ripemd160-hex-latin1 first.

## Output

Returns a RIPEMD-160 hash of the provided Latin1-encoded text, represented as a lowercase hexadecimal string (40 characters). The response reflects a deterministic, fixed-length digest computed without any network calls or LLM involvement.
