## 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 zero-token-purchase-on-base-autonomous-agent-1ba8a1bf
```

Example prompt: Buy me 250,000 ZERO tokens from the autonomous agent and send them to my Base wallet 0xAbC123...def456 — I want to pay with USDC on Base.

## When to prefer this

Choose this endpoint when you specifically want to purchase ZERO tokens on the Base network from an autonomous AI agent experiment, paying $1 USDC per 250,000-token tranche via the x402 pay-per-call protocol with no signup or API key required. It is not suitable for general token swaps, analysis, or purchasing other tokens.

## Known failure modes

- Invalid or malformed Base address (not matching 0x + 40 hex chars) returns validation error
- Payment not received or insufficient USDC causes transaction to fail or not execute
- Thin liquidity pool may result in failed or delayed delivery
- Network congestion on Base may delay confirmation
- x402 payment protocol failure if client doesn't support the protocol

## How this service works

## Output

A JSON object confirming the purchase, including the ZERO token contract address, product name, tranche size (250,000), recipient address, a disclosure warning about above-pool pricing and thin liquidity, the on-chain delivery transaction hash, and delivery status (e.g. 'confirmed').
