## 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 adh-btc-mempool-fees-intelligence-a69de8b7
```

Example prompt: What are the current Bitcoin mempool fees — give me both the regular and priority sat/vB rates so I know what to set for my next transaction.

## When to prefer this

Choose this endpoint when you need clean, sourced Bitcoin mempool fee estimates with provenance metadata (source, timestamp) rather than raw blockchain node calls. Ideal for agents that need fee recommendations without maintaining their own blockchain node or integrating directly with mempool APIs. At $0.01 USDC per call via x402, it suits low-frequency lookups where data freshness within minutes is sufficient.

## Known failure modes

- Upstream blockchain.info unavailability may cause stale or missing data
- Rate limiting if called excessively without payment
- Fee data may reflect a snapshot up to a few minutes old, not real-time mempool depth
- Payment failure via x402 protocol returns 402 status before data is delivered
