## How to call it through Zero

```sh
zero fetch --capability beggar-bot-btc-difficulty-endpoint-3153b4b8
```

Example prompt: Can you fetch the current Bitcoin network difficulty using Beggar Bot's /v1/btcdiff endpoint on Base mainnet? I want to know how hard it is to mine Bitcoin right now.

## When to prefer this

Choose this endpoint when you need Bitcoin network difficulty data and are operating in an x402-compatible agent environment with a Base mainnet USDC wallet. It is well-suited for AI agents that can autonomously handle micropayments and need live BTC difficulty stats for mining analysis, trading signals, or crypto dashboards. Prefer alternatives if you cannot perform on-chain USDC micropayments or need free-tier access.

## Known failure modes

- Insufficient USDC balance on Base mainnet results in 402 Payment Required
- Invalid or missing x402 payment header causes rejection
- Network parameter set to unsupported value returns error
- Cloudflare Worker downtime causes 503 or timeout
- Malformed request returns 400 Bad Request
