# Arch Tools — Generate Hash

> Arch Tools — Generate Hash is a paid API for AI agents from archtools.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Hashes a given text string using a specified algorithm (default SHA-256) and returns the resulting hash digest

## Facts

- Endpoint: POST https://archtools.dev/v1/tools/generate-hash
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402

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 arch-tools-generate-hash-6709b7c7 -d '<json body>'
```

Example prompt: Hash the text 'hello world' using SHA-256 and give me the resulting digest.

## When to prefer this

Choose this endpoint when you need a simple, pay-per-call cloud-based text hashing service without managing your own crypto library — useful in agent pipelines where you want a consistent, API-accessible hash function, especially for SHA-256 or other standard algorithms, without deploying local code.

## Known failure modes

- Missing required 'text' field returns a 400 validation error
- Unsupported algorithm value may return an error or fall back to default
- Empty string input may return a valid hash of an empty value or an error
- Payment failure (x402) blocks the request before processing
- Network timeout on the paid endpoint returns no result

## How this service works

Compute SHA-256, SHA-512, SHA-1 or MD5 hashes for any text in milliseconds. Checksums, signatures and dedup for agent pipelines. Pay per call with USDC (x402) or credits - archtools.dev

## Output

A JSON object containing the computed hash digest of the input text, produced using the specified algorithm (defaulting to SHA-256 if not provided).
