# Blockscout Hot Smart Contracts Stats

> Blockscout Hot Smart Contracts Stats 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 a ranked list of the most active ('hot') smart contracts on a specified blockchain network, sorted by transaction count or gas usage

## Facts

- Price: $0.002/call
- Payment: x402

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-hot-smart-contracts-stats-4d0bed5e
```

Example prompt: Show me the hottest smart contracts on Ethereum (chain_id: 1) right now, ranked by transaction count on a daily scale — give me the top 10.

## When to prefer this

Use this endpoint when you need to discover the most active or trending smart contracts on a specific blockchain by transaction volume or gas consumption. Prefer it over generic search when you want ranked, statistics-driven contract discovery rather than lookup by address or name. Ideal for DeFi research, ecosystem analysis, and identifying popular dapps across Blockscout-supported chains.

## Known failure modes

- Missing required 'scale' query parameter returns a 400 error
- Invalid or unsupported chain_id returns a 404 or empty result
- Unsupported sort/order values may return a 400 validation error
- Rate limiting or payment failure (x402) returns a 402 Payment Required response
- Network-specific endpoints may not have hot contract stats if traffic is low

## 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 paginated list of hot smart contracts on the specified chain, each including contract address hash, name, balance, total gas used, transaction count, verification status, proxy type, reputation score, scam flag, ENS domain, public/private tags, watchlist names, and implementations. Also includes next_page_params for cursor-based pagination.
