Example prompt: Top up my CodeNut account by purchasing the 100x credit bundle — pay $0.01 in USDC on Base using the x402 credit-drop offer.

## When to prefer this

Use this endpoint when an AI agent needs to programmatically top up a CodeNut account with platform credits using a micro-payment of $0.01 USDC on the Base blockchain via the x402 payment protocol, especially when the agent needs to maintain a CodeNut credit balance for ongoing AI tool usage.

## Known failure modes

- Insufficient USDC balance — payment rejected, no credits issued
- Invalid or missing x402 payment header — 402 Payment Required response
- Payment on wrong network (not Base) — transaction fails
- Double-spend or replay attempt — transaction rejected
- Service unavailable — 500 error, credits not issued

## How this service works
