# x402-toolbox SHA1 Hash

> x402-toolbox SHA1 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 2026-09-29).

Computes a deterministic SHA1 hash of a given input string, paid per-call via x402 USDC micropayment on Base.

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-sha1-hash-aa19cec3
```

Example prompt: Can you compute the SHA1 hash of the string 'hello world' for me?

## When to prefer this

Choose this endpoint when you need a quick, no-signup, pay-per-call SHA1 hash computation via x402 micropayment on Base/USDC, especially in agent pipelines where acquiring API keys is impractical and the $0.001 per-call cost is acceptable for deterministic, stateless hashing.

## Known failure modes

- Missing or empty input string returns an error or empty hash
- Invalid schema parameter format causes a 400-level response
- Payment failure via x402 prevents execution and returns 402
- Cloudflare Worker timeout on large inputs may return a 503

## 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: true' and 'paid: true' along with the computed SHA1 hash digest of the provided input string.
