## 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 420world-world-token-purchase-1-usdc-f2a1fda1
```

Example prompt: Buy me 1 USDC worth of WORLD tokens right now — use the x420.dev puff endpoint that swaps exactly 1 dollar of USDC into WORLD tokens at contract address 0xA984E8157B3Cb4e7d5C0fd7E46fFb254A789EB07.

## When to prefer this

Use this endpoint when an agent needs to acquire exactly 1 USDC worth of WORLD tokens in a single atomic call using the x402 micropayment protocol. Prefer the sibling 5 USDC endpoint when a larger purchase is needed. This is the minimum-denomination entry point for programmatic WORLD token acquisition.

## Known failure modes

- Insufficient USDC balance — payment fails and no tokens are purchased
- x402 payment not accepted — API returns 402 status if payment header is missing or malformed
- Swap failure on-chain — swapTransactionHash may be null if the DEX swap fails
- Network congestion — transaction may be delayed or dropped on-chain
- Contract address mismatch — calling wrong endpoint version returns unexpected token
- Rate limiting — repeated rapid calls may be throttled
