## How to call it through Zero

```sh
zero fetch --capability farm-seller-d7c895f0 -d '<json body>'
```

Example prompt: Buy me 500,000 FARM tokens using the FARM Seller — I want to spend $500 USDC and get back the transaction hash confirming the purchase on Base.

## When to prefer this

Use this endpoint when an agent needs to programmatically purchase exactly 500,000 FARM tokens for a fixed $500 USDC price in a single atomic call on the Base network, with no negotiation of price or quantity.

## Known failure modes

- Insufficient USDC balance — payment of $500 not fulfilled
- Payment protocol (x402) failure — transaction not authorized
- On-chain transaction failure — Base network congestion or gas issues
- Invalid wallet address — unable to route FARM tokens
- API unavailable — Vercel deployment error or downtime
