# ONE Engine SHA-512 Hash

> ONE Engine SHA-512 Hash is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Computes a SHA-512 cryptographic hash of any UTF-8 text string, returning the hex digest.

## 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 one-engine-sha-512-hash-41897211 -d '<json body>'
```

Example prompt: Can you SHA-512 hash this string for me: 'hello world'?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call SHA-512 hash computation without spinning up local crypto libraries — especially in agentic pipelines running on Base via x402 micropayments. Prefer it over general-purpose hashing services when cost-per-call pricing and on-chain payment compatibility matter.

## Known failure modes

- Missing or empty 'text' field returns a validation error
- Non-UTF-8 or malformed payload may return a 400 error
- Payment failure via x402 protocol results in a 402 response before hashing occurs
- Network timeout on the Cloudflare Worker edge node

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object containing the SHA-512 hex digest string (128 hex characters), the product identifier 'hash_sha512', and the algorithm label 'SHA-512'.
