## 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 sadf-df-x420-dev-buy-5-usdc-of-df-tokens-f87e495d
```

Example prompt: Buy me $5 worth of df tokens (contract 0x3077c5e15F8BD67F05f73b4dC49a507543FF0b07) using the x420 5-USDC fixed purchase endpoint.

## When to prefer this

Use this endpoint when you want to buy exactly $5 USDC worth of df tokens in a single fixed-amount call without specifying a custom amount. Prefer over the custom-amount sibling endpoint when simplicity and a fixed $5 purchase suffices. Prefer over the $1 sibling when you want a larger fixed purchase. Use when operating within x402-compatible payment infrastructure.

## Known failure modes

- Insufficient USDC balance to cover the $5 payment — payment rejected
- x402 payment protocol failure — transaction not processed
- On-chain swap failure — swapTransactionHash null, tokens not received
- Token contract unavailable or liquidity issues — swap reverts
- Network congestion causing delayed or failed transaction confirmation
