## 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 tokensense-buy-token-via-x402-b49815ad -d '<json body>'
```

Example prompt: Buy the token at Base contract address 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed and send it to my wallet 0xAbC123...456 — use the TokenSense buyToken route.

## When to prefer this

Choose this endpoint when you need to programmatically purchase a specific EVM token on the Base network and deliver it directly to a wallet address, especially in agentic or automated workflows that use the x402 micropayment protocol. Prefer this over manual DEX interactions when you want a single API call to handle the buy-and-deliver flow without managing swap routing yourself.

## Known failure modes

- walletAddress is not a valid EVM address — returns validation error
- buyTokenAddress is Base native USDC contract — explicitly rejected by the API
- buyTokenAddress is not a valid or recognized Base token contract — purchase fails
- x402 payment fails or is insufficient — request rejected with 402 status
- Token liquidity unavailable or swap route not found — purchase cannot be executed
- Network congestion or RPC failure causing transaction timeout

## How this service works

x402-paid TokenSense routes, with parallel MPP routes under /mpp/*.

## Output

Returns confirmation of the token purchase and delivery to the specified wallet, likely including transaction hash, token details, and transfer status on the Base network.
