## 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`):

Example prompt: Buy me 1 USDC worth of Tc tokens on x420 — I want to pick up a small amount of the Tc token at contract 0xfA9C5EF420fb8ED78531F623aD19E51d8EAE5B07.

## When to prefer this

Use this endpoint when you want to programmatically buy exactly 1 USDC worth of Tc tokens via a paid x402 API call. Prefer this over the 5 USDC sibling endpoint when you want a smaller, lower-risk purchase or are testing the integration. Best suited for AI agents operating within x402-enabled payment flows on Base or compatible EVM chains.

## Known failure modes

- Insufficient USDC balance — payment cannot be completed
- Token liquidity too low — swap transaction fails
- On-chain transaction reverted — swapTransactionHash is null with error message
- x402 payment protocol failure — 402 response not resolved
- Smart contract address invalid or paused — purchase blocked
