## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Base Contracts Tracker

Real-time monitor for new smart contract deployments on **Base mainnet**.

### What it does

Scans the latest Base blocks and detects newly deployed smart contracts. For each contract, it returns:

- **Contract address** — the deployed contract
- **Deployer wallet** — who deployed it
- **Block number & timestamp** — when it was deployed
- **Safety score (0-10)** — risk assessment
- **Risk factors** — unverified code, dangerous functions, no ownership renounce
- **Token name & symbol** — if identifiable

### Why use it

- **Security researchers** — detect suspicious deployments in real-time
- **MEV bots** — find new pools and tokens immediately
- **DeFi protocols** — monitor what's being deployed on your chain
- **Auditors** — pre-screen contracts before full audits

### Pricing

The actor runs on **Base mainnet** and returns fresh data every scan.

#### Need recurring access?

Pay **0.0013 ETH** directly to our wallet and get:

- Unlimited API access (no rate limits)
- Real-time contract alerts via XMTP
- Full safety analysis for any contract

**Wallet:** `0xa41A2ab6b3097536484399a8DfA3e6c37C329545` (Base mainnet)

#### Or use the self-service API

```bash
curl -X POST "https://antigravity-connect-ia.vercel.app/api/v1/contract-safety" \
  -H "Content-Type: application/json" \
  -d '{"address": "0x...", "txHash": "0x..."}'
```

Response includes 402 Payment Required with instructions if no txHash provided.

### Input parameters

| Field | Type | Default | Description |
|---|---|---|---|
| `blocksToScan` | number | 100 | Number of recent blocks to scan |

# Actor input Schema

## `startBlock` (type: `integer`):

Block number to start scanning from. If empty, scans from current block - blocksToScan

## `blocksToScan` (type: `integer`):

Number of recent blocks to scan

## `minScore` (type: `integer`):

Only include contracts with safety score >= this value (0-10). 0 = include all

## Actor input object example

```json
{
  "startBlock": 0,
  "blocksToScan": 200,
  "minScore": 0
}
```

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("cipher_zero/base-contracts-tracker").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("cipher_zero/base-contracts-tracker").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{}' |
apify call cipher_zero/base-contracts-tracker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,cipher_zero/base-contracts-tracker"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
