## 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 nine-to-five-nine-buy-5-usdc-of-nine-tokens-62a83a09
```

Example prompt: Buy me $5 worth of nine tokens (contract 0x3a105f1247B27DED116B5d8dFe3D8e24151c1B07) using USDC right now.

## When to prefer this

Use this endpoint when you want to programmatically purchase exactly $5 USDC worth of nine tokens in a single fixed-amount call. Prefer this over the $1 variant when you want a larger fixed purchase, and over the custom-amount endpoint when you specifically want the $5 denomination without specifying a custom value.

## Known failure modes

- Insufficient USDC balance to cover the $5 payment — payment rejected
- x402 payment protocol failure — transaction not completed
- Token liquidity too low to complete swap — swap transaction fails or returns null hash
- Network congestion or RPC error causing transaction failure
- Invalid or expired payment header — authentication error
