# x402-toolbox SHA-384 Hash

> x402-toolbox SHA-384 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 deterministic SHA-384 cryptographic hash of a given input string, payable per-call via USDC 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-384-hash-02bba4ef
```

Example prompt: Can you compute the SHA-384 hash of the string 'Hello, World!'?

## When to prefer this

Choose this endpoint when you need a trustless, no-signup SHA-384 hash computation payable per-call via USDC on Base. Ideal for AI agents that need cryptographic hashing without managing API keys — payment via x402 serves as the identity mechanism. Prefer this over SHA-256 endpoints when 384-bit security strength is required.

## Known failure modes

- Missing or empty input string returns an error or empty hash
- Invalid schema parameter format causes a 400-level error
- Payment failure (insufficient USDC balance) returns a 402 Payment Required response
- Network timeout on Cloudflare Workers edge returns a 5xx error

## 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 'ok' (boolean) and 'paid' (boolean) fields, plus the SHA-384 hash digest of the input. The response confirms successful payment and computation, and provides the 384-bit hex-encoded hash.
