Purchase CodeNut platform credits (10 USDC for 100x value) via x402 payment on Base network.
What it does
This x402 endpoint lets AI agents purchase CodeNut credits by paying 10 USDC on the Base network. The endpoint at `https://pay.codenut.ai/credit-drop/lg` accepts an exact payment of 10,000,000 units (10 USDC, 6 decimals) and returns a JSON object containing the credited amount. The listing explicitly states this is "NOT A TOKEN" — it is a credit purchase for the CodeNut platform, marketed as offering 100x worth of credits relative to the payment.
The payment uses the x402 protocol (version 1) with the "exact" scheme on Base mainnet. The asset is USDC at contract address `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`, and the payment is directed to wallet `0x8d8Fa42584a727488eeb0E29405AD794a105bb9b`. The facilitator infrastructure is hosted at `https://facilitator.codenut.ai/`. The endpoint responds to HTTP GET requests and returns JSON with an `amount` field.
Documentation for the broader CodeNut x402 facilitator is referenced at `https://docs.codenut.ai/guides/x402-facilitator`, though the `/docs`, `/api`, `/pricing`, and `/README` paths on the payment domain all return 404. The exact nature of what "CodeNut credits" unlock (e.g., which services, rate limits, expiration) is not documented in the available material, which limits the ability to fully evaluate this offering.

Quick start
import { createPaymentHeader } from 'x402/client';
// After setting up walletClient on Base:
const paymentHeader = await createPaymentHeader(walletClient, 1, {
scheme: 'exact',
network: 'base',
maxAmountRequired: '10000000',
resource: 'https://pay.codenut.ai/credit-drop/lg',
payTo: '0x8d8Fa42584a727488eeb0E29405AD794a105bb9b',
asset: '0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913',
maxTimeoutSeconds: 60,
extra: { name: 'USD Coin', version: '2' }
});
const res = await fetch('https://pay.codenut.ai/credit-drop/lg', {
headers: { 'X-PAYMENT': paymentHeader }
});
const data = await res.json(); // { amount: ... }Example
Response

"amount": 1000
}Endpoint
Quality
The x402 challenge provides clear payment parameters, but there is no OpenAPI spec, no accessible documentation (all doc paths return 404), and no explanation of what CodeNut credits actually provide or how the 100x value claim is substantiated. The response schema only specifies an amount field with no further detail. Significant inference is required.
Warnings
- —No documentation available — /docs, /api, /pricing, /README all return 404
- —The '100x worth of credits' claim is unsubstantiated in available material
- —What CodeNut credits unlock (services, limits, expiration) is entirely undocumented
- —The example response amount value is inferred; no actual successful response was observed
- —No agents.txt or robots.txt present
