## 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 megaeth-mga-token-purchase-1-usdc-x420-dev-190d8a77
```

Example prompt: Buy me 1 USDC worth of MGA (Megaeth) tokens using my wallet — I want to pick up a small amount of MGA on x420.dev right now.

## When to prefer this

Use this endpoint when an agent needs to programmatically purchase a small (1 USDC) fixed amount of MGA tokens via the x402 payment protocol. Prefer this over the 5 USDC sibling endpoint when a minimal, low-cost test purchase or fractional acquisition is desired. Best suited for automated DeFi workflows that need on-chain MGA token acquisition without a manual exchange UI.

## Known failure modes

- Payment of exactly 1 USDC not received — transaction fails or returns error
- Insufficient liquidity for MGA swap — swap transaction hash may be null or error returned
- On-chain transaction reverted — returns error message with null hashes
- Network congestion causing delayed or dropped transactions
- Invalid or missing x402 payment header — request rejected before processing
