## 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

## GST Verification Apify Actor

This Apify actor verifies GST (Goods and Services Tax) numbers and retrieves detailed taxpayer information from the official Indian GST portal.

### Features

- ✅ Verifies GST numbers using the official GST portal
- ✅ Handles session management automatically
- ✅ Fetches captcha images for verification
- ✅ Retrieves comprehensive GST taxpayer details
- ✅ Returns structured JSON data
- ✅ Easy to integrate with Apify platform

### Input

The actor accepts the following input parameters:

```json
{
  "GSTIN": "27CEGPN9391P1ZF",
  "captcha": "ABC123"
}
```

#### Input Parameters

- **GSTIN** (required): The GST Identification Number to verify (15 characters)
  - Format: `27CEGPN9391P1ZF`
  - Example: `27AAPFU0939F1Z5`

- **captcha** (optional): The captcha text to solve
  - If not provided, the actor will output the captcha image and require manual input
  - You can use captcha solving services or solve it manually

### Output

The actor outputs GST details in the following format:

#### Success Response

```json
{
  "gstin": "27CEGPN9391P1ZF",
  "status": "success",
  "data": {
    "adhrVFlag": "Yes",

    },
    "rgdt": "Registration Date",
    "stj": "Division",
    "sts": "Status",
    "tradeNam": "Trade Name"
  }
}
```

#### Captcha Required Response

```json
{
  "gstin": "27CEGPN9391P1ZF",
  "captchaImage": "data:image/png;base64,...",
  "status": "captcha_required",
  "message": "Please solve the captcha and provide it in the input"
}
```

#### Error Response

```json
{
  "gstin": "27CEGPN9391P1ZF",
  "error": "Error message",
  "status": "error"
}
```

### Usage

#### Using Apify Console

1. Go to [Apify Console](https://console.apify.com/)
2. Create a new actor or use this actor
3. Configure the input with your GSTIN
4. Run the actor
5. If captcha is required, solve it and provide it in the input
6. Retrieve the results from the dataset

#### Using Apify API

```python
from apify_client import ApifyClient

## Initialize the ApifyClient
client = ApifyClient("YOUR_API_TOKEN")

## Prepare the actor input
run_input = {
    "GSTIN": "27CEGPN9391P1ZF",
    "captcha": "ABC123"  # Optional, if not provided, captcha image will be returned
}

## Run the actor
run = client.actor("YOUR_USERNAME/gst-verification").call(run_input=run_input)

## Fetch results from the default dataset
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)
```

#### Using cURL

```bash
curl -X POST \
  https://api.apify.com/v2/acts/YOUR_USERNAME~gst-verification/runs \
  -H 'Authorization: Bearer YOUR_API_TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{
    "GSTIN": "27CEGPN9391P1ZF",
    "captcha": "ABC123"
  }'
```

### Workflow

1. **Initialize Session**: The actor creates a session with the GST portal
2. **Fetch Captcha**: Retrieves a captcha image from the GST portal
3. **Solve Captcha**: If captcha is provided, proceeds to verification; otherwise, outputs captcha image
4. **Verify GSTIN**: Submits GSTIN and captcha to the GST portal
5. **Retrieve Details**: Fetches and returns comprehensive GST taxpayer details

## CLI example

```bash
echo '{
  "GSTIN": "27CEGPN9391P1ZF"
}' |
apify call mikolabs/gst --silent --output-dataset

```

## MCP server setup

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

```

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).
