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 blockscout-chain-stats-api-79fc9290
```

Example prompt: Pull up the current blockchain network stats for Ethereum mainnet from Blockscout — I want to see things like total transactions, block count, and address activity.

## When to prefer this

Use this endpoint when you need aggregate network-level statistics for a specific blockchain chain (identified by chain_id) and want Blockscout's indexed data. Prefer this over raw RPC calls when you need pre-aggregated metrics like total transactions, total addresses, or token counts rather than individual block or transaction data. Best suited for dashboards, monitoring, and research scenarios where a holistic chain summary is needed.

## Known failure modes

- Invalid or unsupported chain_id returns a 404 or error response
- Chain not indexed by Blockscout returns empty or error
- Network timeout if Blockscout indexer is under load
- Stale data if indexer is behind the chain tip
- Payment failure if x402 USDC payment is not processed correctly

## How this service works

Access to api/v2/stats. Retrieve blockchain network statistics and metrics

## Output

Returns a JSON object containing blockchain network statistics for the specified chain, likely including total transaction count, total block count, number of addresses, gas usage metrics, token counts, and other network-level summary metrics as tracked by Blockscout's indexer.
