# RIPEMD-160 Base32 Digest

> RIPEMD-160 Base32 Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-01).

Computes a RIPEMD-160 cryptographic hash of input text and returns it encoded as a Base32 string, with no network calls or LLM involvement.

## Facts

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-base32-digest-c29cf50d -d '<json body>'
```

Example prompt: Can you compute the RIPEMD-160 hash of the text 'Hello, world!' and give it to me encoded as Base32?

## When to prefer this

Choose this endpoint when you specifically need a RIPEMD-160 digest (not SHA-256, SHA-1, or other algorithms) and want the output in Base32 encoding rather than hex or Base64. It is ideal for deterministic fingerprinting, checksums, or compatibility with systems that expect RIPEMD-160 hashes in Base32 format. Prefer the free sandbox endpoint /v1/sandbox/digest-ripemd160-base32 for testing before paying $0.006 USDC per call on this production endpoint.

## Known failure modes

- Empty or missing text field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid key parameter may cause authentication failure
- Incorrect payment amount causes a 402 Payment Required response

## How this service works

Call when an agent needs a ripemd160 digest of text, encoded as base32. No network and no LLM. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-ripemd160-base32 first.

## Output

A RIPEMD-160 cryptographic digest of the provided text, returned as a Base32-encoded string. The result is deterministic and produced entirely offline without any network requests or AI inference.
