## How to call it through Zero

```sh
zero fetch --capability x402-farm-pdf-endpoint-976ba96b
```

Example prompt: Can you fetch that PDF for me using the x402-farm pay-per-call API — it's just $0.01 USDC on Base and I don't need to create an account?

## When to prefer this

Choose this endpoint when an AI agent needs to retrieve a PDF document without API key registration, using a crypto-native micropayment model (x402 protocol, USDC on Base). Ideal for agent pipelines that require pay-per-use access patterns, low-cost per-call pricing ($0.01 USDC), and no account overhead. Prefer over traditional REST PDF APIs when operating in a Web3 or agentic context where wallet-based payments are already available.

## Known failure modes

- Payment not included or insufficient USDC balance — returns 402 Payment Required
- Invalid or malformed x402 payment header — returns 400 Bad Request
- PDF resource not found or unavailable — returns 404 Not Found
- Network or Vercel hosting issue — returns 500 Internal Server Error
- Payment settled but document delivery failed — partial or empty response
