# Blockscout Chain Stats Counters

> Blockscout Chain Stats Counters 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 statistical counters (transaction counts, address counts, token counts, etc.) for a specified blockchain network via Blockscout's stats service

## 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-counters-c403cf1f
```

Example prompt: Pull the aggregate stats counters for Ethereum from Blockscout — I want to see the total number of transactions, addresses, and any other network-level counts available for that chain.

## When to prefer this

Use this endpoint when you need high-level aggregate statistics (total counts) for an entire blockchain network rather than specific transaction or address details. Prefer this over transaction-lookup or address-lookup endpoints when the goal is network-wide metrics dashboards, chain health monitoring, or cross-chain comparison of activity levels. Ideal when you need a quick snapshot of how large or active a chain is.

## Known failure modes

- Invalid or unsupported chain_id returns an error or empty counters array
- Chain not indexed by Blockscout returns 404 or empty response
- Temporary stats service downtime returns 5xx error
- Missing chain_id path parameter causes request routing failure
- Payment failure (402) if x402 payment is not provided or insufficient

## How this service works

## Output

Returns a JSON array of counter objects for the specified chain, each containing an id, title, units, current value (as a string), and a human-readable description of what the counter measures (e.g. total transactions, total blocks, total addresses, total tokens).
