# x402-toolbox SHA-512 Hash

> x402-toolbox SHA-512 Hash is a paid API for AI agents from x402-toolbox.shablony-pro.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Computes a SHA-512 cryptographic hash of a given input string via a pay-per-call API over 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 x402-toolbox-sha-512-hash-053f9573
```

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

## When to prefer this

Choose this endpoint when you need a quick, no-signup SHA-512 hash computation paid per-call via USDC over x402, especially in autonomous agent workflows where managing API keys is undesirable and micro-payment identity is sufficient.

## Known failure modes

- Missing or empty input string returns an error or empty hash
- Payment not fulfilled results in 402 response blocking execution
- Invalid schema parameter may yield unexpected output or error
- Network timeout from Cloudflare Worker edge node
- Malformed JSON response if Worker encounters an unhandled exception

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with an 'ok' boolean indicating success, a 'paid' boolean confirming payment was processed, and presumably the resulting SHA-512 hash digest of the input string.
