## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## SignalBase - Funding & Business Signals API

Access real-time funding rounds, acquisitions, hiring signals, executive job changes, investor profiles, and company data — all from a single Apify Actor. No signup required.

SignalBase aggregates business intelligence from across the web and delivers it through a clean, filterable API. Use it to power lead generation, investment research, competitive intelligence, and market analysis.

### What data is available?

| Endpoint | Description | Key fields |
|----------|-------------|------------|
| **Funding Signals** | New funding rounds as they happen | Company, round type, amount, investors, date |
| **Acquisition Signals** | Companies showing acquisition indicators | Company, signal score, indicators |
| **Hiring Signals** | Open job postings with company context | Job title, location, seniority, department, company |
| **Job Change Signals** | Executive and leadership role changes | Person, new role, company, LinkedIn URLs |
| **Investors** | VC, angel, PE, and corporate investor profiles | Firm, AUM, focus areas, check size, portfolio |
| **Companies** | Company profiles with growth data | Name, industry, headcount, growth rates, location |

### How to use

#### Run from Console or API

Select a signal type, set your filters, and the Actor will fetch matching results. The full API response (including `data`, `pagination`, and `meta`) is available in **Output**, and individual records are also stored in the **Dataset** as JSON, CSV, or Excel.

**Example input:**

```json
{
  "signalType": "funding",
  "date_preset": "last_30d",
  "countries": "US,GB",
  "round": "Seed,Series A",
  "limit": 50
}
````

#### Standby mode (real-time API)

When the Actor runs in Standby mode, it exposes a live HTTP server. Send GET requests directly with query parameters — just like a REST API.

**Available endpoints:**

```
GET /signals/funding?countries=US&round=Seed&date_preset=last_30d
GET /signals/acquisitions?search=fintech&countries=US
GET /signals/hiring?positions=cto,vp%20of%20engineering&seniorities=c_level
GET /signals/job-changes?departments=engineering&seniorities=c_level,vp
GET /signals/investors?categories=vc,angel&countries=US
GET /companies?search=AI&employee_count_min=50&employee_count_max=500
```

### Response examples

Every endpoint returns the same envelope: `success`, `data` (array), `pagination`, and `meta`.

# 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("signalbase/signalbase-api").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}`);

## 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("signalbase/signalbase-api").call(run_input=run_input)

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