## 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 run-x420-dev-8a8cb012 -d '<json body>'

## When to prefer this

Use this endpoint when you need to buy a specific custom USDC amount of RUN tokens rather than a fixed 1 USDC amount. Choose this over the fixed endpoint when your user wants to invest more than 1 USDC or a precise dollar figure in RUN tokens in a single call.

## Known failure modes

- Insufficient USDC balance to cover trade amount plus $5 API fee
- Invalid or missing USDC amount parameter
- On-chain transaction failure due to slippage or liquidity issues
- Payment authorization failure for the $5 USDC API fee
- Network congestion causing transaction timeout
