# agent-services x402 Hashing Tool

> agent-services x402 Hashing Tool is a paid API for AI agents from 49112-hjhjtioxvirqvcvo.splox.app, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-02).

Computes a cryptographic hash (e.g. SHA-256) of a given input string, paid per-call via x402 USDC 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 agent-services-x402-hashing-tool-4fe51f82
```

Example prompt: Can you compute the SHA-256 hash of the string 'hello' for me?

## When to prefer this

Choose this endpoint when an AI agent needs a quick, pay-per-use cryptographic hashing operation without setting up any local compute infrastructure. Especially useful in agent workflows that need data integrity verification, deduplication fingerprinting, or token hashing on-demand, billed in micro-USDC via x402 on Base.

## Known failure modes

- Missing or empty input string returns an error response
- Unsupported algorithm name returns an error
- Payment not provided or insufficient USDC via x402 returns 402 Payment Required
- Network timeout or service unavailability returns 5xx error

## How this service works

Paid per-call web tools for AI agents: DNS, TLS, robots.txt, hashing, JavaScript rendering and screenshots. Payment over x402 (USDC on Base).

## Output

Returns a JSON object with two fields: 'algo' indicating the hashing algorithm used (e.g. 'sha256') and 'digest' containing the resulting hexadecimal hash string (e.g. a 64-character sha256 hex digest).

## Response schema (JSON Schema)
