# Blockscout Chain Stats - Main Page Metrics

> Blockscout Chain Stats - Main Page Metrics is a paid API for AI agents from api.blockscout.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-10).

Returns aggregate blockchain statistics for a specific chain including total blocks, addresses, transactions, average block time, and daily transaction charts

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-main-page-metrics-6be61399
```

Example prompt: Can you pull the main blockchain stats for the Base chain using Blockscout — I want to see total blocks, total transactions, average block time, and how many new transactions happened yesterday?

## When to prefer this

Use this endpoint when you need a high-level summary of blockchain health and activity for a specific chain indexed by Blockscout — particularly when you want aggregate counters (blocks, addresses, transactions) plus a daily transaction chart in a single call. Prefer this over transaction-specific or address-specific endpoints when the goal is a dashboard-style overview rather than granular on-chain data.

## Known failure modes

- Invalid or unsupported chain_id returns an error or empty response
- Chain ID not recognized by Blockscout returns 404 or empty data
- Stats service temporarily unavailable returns 5xx
- Some chart data points marked as is_approximate=true when real-time data is incomplete
- OP Stack fields absent for non-OP Stack chains

## How this service works

Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data

## Output

A JSON object containing labeled stat cards (id, title, units, value, description) for total blocks, total addresses, average block time, total transactions, yesterday's transactions, and operational transactions, plus time-series chart arrays for daily new transactions (with date, value, date_to, and is_approximate fields). OP Stack chains also include op_stack-prefixed variants of operational transaction metrics.
