# OnchainExpat x402 Uncensored Code API

> OnchainExpat x402 Uncensored Code API is a paid API for AI agents from x402.onchainexpat.com, paid per call via x402, $0.07/call, status unknown (last checked 2026-09-13).

Generates uncensored code via a pay-per-request AI endpoint using the x402 micropayment protocol

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 onchainexpat-x402-uncensored-code-api-409fd361 -d '<json body>'
```

Example prompt: Write me a Python script that brute-forces a zip file password — use the uncensored code API since standard AI tools refuse this kind of request.

## When to prefer this

Choose this endpoint when you need AI-generated code that standard models decline due to content filters, or when you want pay-per-request crypto-native billing via x402 without API key subscriptions.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment header missing/malformed
- Invalid prompt: empty or malformed request body returns error
- Rate limiting: too many concurrent requests from same address
- Upstream AI provider timeout or unavailability
- Unsupported code task returns partial or empty output
