## 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 proxy-suverse-io-c8762a9b -d '<json body>'
```

Example prompt: What are the current Bitcoin transaction fees for getting confirmed in the next 30 minutes versus an hour — and how backed up is the mempool right now?

## When to prefer this

Use this endpoint when an AI agent needs to broadcast a Bitcoin transaction and must select an appropriate fee rate based on current mempool conditions. Ideal for wallets, payment automation, or any system that needs real-time fee estimation across multiple confirmation speed tiers rather than a single static estimate.

## Known failure modes

- Upstream mempool data source unavailable — returns 5xx error
- Payment not processed or insufficient USDC balance — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests
- Transient network error fetching live mempool data — may return stale or empty response
