# hash.agentutil.net Hash Generator

> hash.agentutil.net Hash Generator is a paid API for AI agents from hash.agentutil.net, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Computes a cryptographic or checksum hash of an input string using a chosen algorithm and output encoding

## Facts

- Endpoint: POST https://hash.agentutil.net/v1/hash

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 hash-agentutil-net-3212eb9c -d '<json body>'
```

Example prompt: Can you hash the string 'HelloWorld2024!' using SHA-256 and give me the result in hex encoding?

## When to prefer this

Use this endpoint when you need a quick, on-demand hash of a single string without setting up a local cryptography library — especially useful for agents that need to verify data integrity, fingerprint content, or generate checksums across multiple algorithms and encodings via a simple API call.

## Known failure modes

- Invalid or unsupported algorithm enum value returns a 400 error
- Invalid encoding value outside hex/base64 returns a 400 error
- Empty or missing input string may return a 400 or empty hash
- Payment failure via x402 protocol returns a 402 Payment Required
- Network timeout or service unavailability returns a 5xx error

## How this service works

Generate a hash of the input string

## Output

Returns the computed hash digest of the input string in the specified encoding (hex or base64), produced by the chosen algorithm (md5, sha1, sha256, sha512, or crc32).
