## 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 x402-bigbug-ai-334172f2 -d '<json body>'
```

Example prompt: Swap 50 USDC for the token at address 0x4200000000000000000000000000000000000006 on Base using the best available DEX route, with a max slippage of 1%.

## When to prefer this

Use this endpoint when you need to programmatically execute a USDC-to-ERC20 swap on Base with optimal routing across multiple DEXes. Ideal for AI agents automating on-chain token purchases, especially when combined with sibling endpoints for token intelligence and trending token discovery. Prefer this over single-DEX integrations when best execution price matters.

## Known failure modes

- Insufficient USDC balance in wallet — returns balance error
- Token address not found or not tradeable on Base DEXes — returns invalid token error
- Slippage exceeded — swap reverted due to price movement beyond tolerance
- Low liquidity for target token — returns liquidity error or high price impact warning
- Network congestion causing transaction failure — returns timeout or gas error
- Invalid wallet address format — returns validation error
