G2 Scraper API

The Piloterr G2 Scraper API lets you extract public data from G2 as clean, structured JSON — no proxies, headless browsers or HTML parsing to maintain. Endpoints available in production:

G2 Product Info API — Read a G2 product reviews page: rating, pricing, categories, alternatives, screenshots, and the reviews shown on the page.

Use it for lead generation, CRM enrichment, market mapping, investment research or job market analytics.

Endpoint	Path	Credits	What you get
G2 Product Info API	`/v2/g2/product/info`	2	Read a G2 product reviews page

How it works

Create a free Piloterr account and copy your API key from the dashboard.
Send a GET (or POST) request to https://api.piloterr.com/v2/... with the header x-api-key: YOUR_API_KEY.
Receive structured JSON — Piloterr handles rendering, proxies, retries and parsing.

export PILOTERR_API_KEY="your-api-key"
pip install requests        # Python
# TypeScript: Node.js 18+ (native fetch), run with `npx tsx file.ts`

Every endpoint accepts both GET (query string) and POST (JSON body with the same fields).

G2 Product Info API

Python example

import json
import os
import requests

response = requests.get(
    "https://api.piloterr.com/v2/g2/product/info",
    headers={"x-api-key": os.environ["PILOTERR_API_KEY"]},
    params={
        "query": "postman",
    },
    timeout=120,
)
response.raise_for_status()
data = response.json()

print(json.dumps(data, indent=2, ensure_ascii=False)[:2000])

One API key, hundreds of sources — G2 plus many other e-commerce, search and company data endpoints in the Piloterr library.
Any language — plain HTTPS + JSON, with examples for Python, TypeScript, cURL, PHP, C#, Go, Java, Ruby and Node.js.

FAQ

Is it legal to scrape G2?

Collecting publicly available data is generally allowed in many jurisdictions, but rules depend on your country, the data you collect and how you use it. Avoid personal data unless you have a lawful basis, respect the website's terms where they apply, and get legal advice for your specific use case. This is not legal advice.

Do I need proxies or a headless browser?

No. Piloterr handles rendering, proxy rotation and retries on its side. You only send an HTTPS request with your x-api-key header and receive JSON.

How much does a request cost?

Credits per call: /v2/g2/product/info 2. See the Piloterr website for plans.

What data does the G2 API return?

Each endpoint returns structured JSON: G2 Product Info — rating, reviews[], reviews[].reviewer, reviews[].review_id, reviews[].review_link, reviews[].publish_date.

Can I get the raw HTML instead of JSON?

Yes. Set return_page_source=true and the response becomes {"result": "..."} with the page source.

Which languages are supported?

Any language that can make an HTTP request. This README shows Python and TypeScript; the examples/ folder contains cURL, PHP, C#, Go, Java, Ruby and Node.js.
