# Blockscout Interchain Stats - Main Page Metrics

> Blockscout Interchain 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 2026-09-11).

Returns aggregate interchain (cross-chain) message statistics for a specified blockchain network, including total messages sent and received.

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-interchain-stats-main-page-metrics-a4999d3b
```

Example prompt: Can you pull up the interchain messaging stats for Ethereum mainnet from Blockscout — I want to know the total cross-chain messages sent and received for that chain?

## When to prefer this

Use this endpoint when you need a quick summary of interchain (cross-chain) messaging volume for a specific blockchain network. It is ideal for dashboards, analytics pipelines, or agent workflows monitoring cross-chain activity levels. Prefer this over full transaction search endpoints when only aggregate interchain statistics are needed.

## Known failure modes

- Invalid or unsupported chain_id returns an error or empty response
- Chain with no interchain activity may return zero values
- Network downtime may result in 503 or timeout
- Malformed path parameter causes 400 Bad Request

## 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

Returns a JSON object with three metric objects — total_interchain_messages, total_interchain_messages_sent, and total_interchain_messages_received — each containing an id, title, units, value, and description string, representing aggregate cross-chain messaging activity for the specified chain.
