Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 blockchain-com-explorer-gateway-bitcoin-hash-rate-chart-9e7b278b -d '<json body>'
```

Example prompt: Pull me the Bitcoin network hash rate chart for the last year from Blockchain.com, using an 8-hour rolling average and daily sampling.

## When to prefer this

Use this endpoint when you need historical Bitcoin network hash rate data with flexible time ranges and rolling average smoothing, served via a micropayment (x402) model. Prefer over free alternatives when you need reliable uptime, programmatic access, and Blockchain.com's authoritative dataset. Best for dashboards, research, and monitoring workflows that need periodic hash rate pulls.

## Known failure modes

- Invalid timespan format returns an error (e.g. unsupported string like '2w')
- Invalid rolling average window string causes a parameter error
- Payment failure (x402) if USDC balance is insufficient
- Empty or sparse result set if sampled=true reduces points too aggressively for short timespans
- Network timeout for very large date ranges without sampling
