# Blockscout Contract Statistics by Chain

> Blockscout Contract Statistics by Chain is a paid API for AI agents from api.blockscout.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-12).

Returns contract deployment statistics for a specific blockchain network, including total contracts, new contracts in 24h, total verified contracts, and new verified contracts in 24h.

## 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-contract-statistics-by-chain-1a870c54
```

Example prompt: Using Blockscout, pull the smart contract stats for Ethereum — I want to know the total number of contracts deployed, how many went live in the last 24 hours, and how many are verified.

## When to prefer this

Choose this endpoint when you need aggregate contract statistics for a specific blockchain chain — particularly total deployment counts, recent 24-hour activity, and verification ratios. It is ideal for ecosystem health dashboards, developer analytics, and monitoring smart contract activity trends. Prefer this over transaction-level endpoints when you need summary-level contract metrics rather than individual contract details.

## Known failure modes

- Invalid or unsupported chain_id returns an error or empty response
- Chain not indexed by Blockscout returns no data
- Network outage on Blockscout infrastructure causes timeout
- Rate limiting if called excessively without proper credentials
- Malformed chain_id path parameter causes 400 or 404 error

## Output

Returns a JSON object with four statistical fields: total_contracts (cumulative contracts deployed), new_contracts_24h (contracts deployed in the last 24 hours), total_verified_contracts (total contracts with verified source code), and new_verified_contracts_24h (newly verified contracts in the last 24 hours). Each field includes an id, title, units, value, and description.
