G2 Scraper
G2 Scraper
The G2 Scraper turns any of G2's 240,975 product profiles into structured JSON. One GET request returns:
- The product's website and its contacts — emails, phone numbers, social profiles, and the technologies it runs, extracted by our open-source Website Email Contact Scraper. Only ~2% of G2 products list a website on their profile — we find it with AI for the rest (
likely_product_website) - Ratings and pricing — overall score and every listed plan with features
- Company details — seller, location, founded year, alternatives, comparisons, and social profiles
More endpoints cover reviews, category listings, and the complete product directory.
For reviews, G2 itself stops serving them after page 10 — when you paginate past that, we automatically combine multiple filters behind the scenes to keep the reviews coming, giving you more reviews than G2 provides on its own.
Rated Excellent on Trustpilot — 4.6 from 25 reviews — and 1,000+ developers have sponsored our open source work on GitHub.

}Trimmed for readability — the full response carries 40+ fields. Complete samples are in the API Reference.
Postman doesn't list a website on its G2 profile (product_website: null) — like ~98% of G2 products. We find it with AI (likely_product_website), then crawl it with our open-source Website Email Contact Scraper to pull the emails, phone numbers, and social profiles you see above.

What Data Can You Get from G2?
Every G2 product profile breaks down into fields the API returns as clean JSON:
- Product website + contacts — the product's website (AI-found when the G2 profile doesn't list it) with the emails, phone numbers, social profiles, and technologies found on it, via our open-source Website Email Contact Scraper
- Reviews — full text, question/answer breakdown, rating, publish date, reviewer name, job title, and company size, with filters for stars, segment, industry, role, region, and keywords
- Ratings — overall score and total review count
- Pricing — every listed plan with price, description, and features
- Feature scores — per-feature satisfaction percentages with the review counts behind them
- Market position — alternatives, head-to-head comparisons, and categories
- Company — seller, location, founded year, employee count, website, and social profiles with follower counts
The category endpoint adds buyer context per product: common user job titles, top industries, and the market-segment split across Small-Business, Mid-Market, and Enterprise. Coverage spans 240,975 G2 products in 2,227 categories.
API Reference
All endpoints are GET requests against https://g2-scraper.omkar.cloud, authenticated with the API-Key header, returning JSON.
Product Details & Reviews
▶ Try it live in the Playground — free, no signup →
GET https://g2-scraper.omkar.cloud/g2/products?product=postman
Pass a G2 product slug (postman) or the full product URL — either works. Optional website_contacts_crawl_mode controls contact enrichment: homepage (default — scan the website's homepage), deep (also crawl its top contact-like pages: contact, about, careers, blog), or off.
Returns the product's website and the contacts found on it (emails, phone numbers, social profiles, and technologies as website_contacts), plus 40+ fields: rating, pricing plans, feature scores, alternatives, comparisons, company details, and social profiles.

FAQs
Can I try the G2 Scraper API before signing up?
Yes — the playground runs live requests in your browser with no account and no API key. Try it in the Playground →
How do I scrape G2 reviews?
Call the reviews endpoint (GET /g2/reviews?product=postman&page=1) with a product slug or URL. It returns 10 reviews per page — full text, question/answer breakdown, rating, publish date, reviewer name, job title, and company size — with filters for stars, company segment, industry, reviewer role, region, keywords, and sort order.
G2 itself stops serving reviews after page 10. When you paginate past that, we automatically combine multiple filters behind the scenes to keep the reviews coming — so you get more reviews than G2 provides on its own.
How does the API find product emails, phone numbers, and social profiles?
Only ~2% of G2 products list a website on their G2 profile. For the other 98%, we use AI to find the product's real website — returned as likely_product_website. That website is then crawled by our open-source Website Email Contact Scraper, and every email, phone number, social profile, and technology it finds comes back as website_contacts, each with the source pages and an is_likely_official flag.
Want the same contact extraction for any website, free? Get the Website Email Contact Scraper on GitHub →
What's the difference between the API and the dataset downloads?
Three things live on this page. The API returns full product data on demand, metered by your monthly quota. The free downloads are directory files — every product and category link — for discovering what to scrape. The paid dataset is the freshly re-crawled full corpus, for when a months-old snapshot isn't enough.
How fresh is the data, and how do I get the newest?
API responses come from a pre-crawled snapshot that can be a few months old. The freshest data is the full re-crawled dataset, available for purchase — the contact links are under Free G2 Dataset Downloads. (The free directory files there come from the same snapshot as the API.)
Can I pass a slug instead of a full URL?
Yes. Product Details & Reviews and Products by Category accept either — postman and the full G2 product URL behave identically.
How many reviews can I get per product?
Reviews come 10 per page. G2 itself caps every filter combination at 10 pages — but when you paginate past page 10, we automatically apply multiple filter combinations (stars, company segment, and more) behind the scenes and keep serving fresh reviews, giving you more than G2 provides on its own.
How do I discover products and categories to scrape?
The Product Links and Category Links endpoints return the complete directories — 240,975 products and 2,227 categories — and the same files are free to download.
Who's Behind the G2 Scraper API?
Omkar Cloud is run by the developers who build the APIs — write in and an engineer answers, not a support script. What you can check for yourself:
- 4.6 from 25 reviews on Trustpilot
- 1,000+ developers sponsor our open-source work on GitHub
- Every paid plan carries a 90-day, 2-click refund
The same API pattern powers our Capterra and Trustpilot scrapers.
More Review-Data APIs: Google Maps, Capterra & Trustpilot
- Google Maps Scraper (3,100+ GitHub Stars) — need tens of thousands of leads? Type a niche and a city ("dentists in New York") and get every matching business as a ready-to-call lead list — name, address, phone, website, emails, rating, and reviews. The free tier alone pulls up to 100K leads a month, enough to run your entire outreach pipeline on $0.
- Website Email Contact Scraper — the same contact engine this API uses, free and open source: point it at any website and get every email, phone number, and social profile on it, each with source pages and an official/unofficial flag.
- Capterra Scraper API — the same clean JSON for 108,726 Capterra products, with 5-dimension rating breakdowns (ease of use, value for money, support…), pricing plans, integrations, and pros/cons. Cross-reference a vendor's G2 and Capterra ratings before you trust either.
- Trustpilot Scraper API — real-time data for 1.6M+ companies, pulled live: keyword search, full profiles with rating distributions, and every review for any domain. 200 free requests/month.

Love It? Review It ⭐
From one developer to another: if the G2 Scraper API saved you time, please leave a review on Trustpilot. It takes less than a minute, and it means a lot.
Here's why it matters. Most people do judge an API by its reviews. Your review helps another developer — someone just like you, deciding whether the G2 data here is real and reliable — find this API and build with confidence.
It takes only 60 seconds, and I will personally thank you for it.
