# X Pay Random Data Generator

> X Pay Random Data Generator is a paid API for AI agents from www.api-xpay.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Returns a random hex string and integer with metadata including network and asset context, billed per-request 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 x-pay-random-data-generator-f3a0d3bc
```

Example prompt: Can you fetch me a random hex value and integer right now using the X Pay random data API — I just need one fresh random result billed to my USDC wallet on Base.

## When to prefer this

Choose this endpoint when you need a lightweight, on-demand random hex or integer value and are operating in a pay-per-use x402/USDC environment on Base. It is ideal for developers who want random data without managing a random-number-generator service themselves, and who are already integrated with x402 micropayment flows. Prefer alternatives if you need large volumes of random data (cost adds up per call), cryptographic-grade randomness with auditable entropy sources, or if you are not set up for USDC payments on Base.

## Known failure modes

- Payment failure: x402 payment not accepted or USDC balance insufficient — returns 402 Payment Required
- Invalid HTTP method: using POST or PUT returns method-not-allowed error
- Network error: Base network congestion may delay payment verification
- Malformed headers: non-string header values rejected by schema validation

## How this service works

Generate a random integer and hex bytes

## Output

A JSON object containing: a 16-byte random hex string ('hex'), a random integer ('integer'), the number of bytes ('bytes'), the blockchain network ('network': 'base'), the payment asset ('asset': 'USDC'), and a success boolean. Each call costs $0.005 USDC.
