## 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 beggar-bot-btc-mempool-lookup-base-mainnet-6af05d78
```

Example prompt: Can you check the current Bitcoin mempool status and tell me how congested the network is right now — I want to know if it's a good time to send a BTC transaction?

## When to prefer this

Use this endpoint when you need real-time Bitcoin mempool data within an agentic workflow that already supports x402 micropayments on Base mainnet. At $0.02 USDC per call it is cost-effective for occasional spot checks or monitoring loops. Prefer this over scraping block explorer UIs or heavier RPC node connections when you want a simple REST JSON interface with pay-per-use pricing.

## Known failure modes

- Payment not received — x402 payment of $0.02 USDC on Base mainnet required before data is returned
- Invalid or missing payment header results in 402 response
- Bitcoin mempool data source temporarily unavailable or stale
- Malformed query parameters return error JSON
- Network connectivity issues to underlying BTC mempool data provider
