How the G2 API works

G2 is a normal SocialCrawl commerce surface. You call GET /v1/g2/… with an API key, spend credits on live misses, and get a single JSON envelope back.

Authenticate every call

Send your key in the x-api-key header. No G2 partner app for public reads. The same key works across SocialCrawl platforms.

GET with query params

All G2 routes are GET. Pass id, url, category, page, sort as query strings. We validate formats before charging.

Pay in credits, not seats

The category taxonomy dump costs 1 credit. Product, reviews, category listings, seller, seller products, and the product index cost 5 credits. Cache hits cost 0. Empty or hard failures refund.

Read one JSON envelope

Every response is the same shape: success, data, credits_used, credits_remaining, request_id, cached. Lists also carry pagination when the route pages.

The usual integration chain

Most products start from the category taxonomy or a known slug, then deepen only the products that matter.

01Taxonomy

GET /v1/g2/categories

Category URL plus slug rows

Resolve a category before listing products in it.

02Category

GET /v1/g2/category?category=…

ProductList cards with slugs and ratings

Pick candidates before spending on full product detail.

03Product

GET /v1/g2/product?id=…

Full Product for one slug

Category cards are not a full listing record.

04Reviews

GET /v1/g2/reviews?id=…

ReviewList for the same slug

Written review text lives on reviews, not product.

What lands in data

Field names match other SocialCrawl commerce platforms. Parse once, reuse across G2, Amazon, and Trustpilot.

Productproduct

id (slug), title, rating, review count, categories, seller, plans, features, url

ReviewListreviews

items[] with author, content.text, rating, published_at; cursor when more remains

ProductListcategory, seller/products

category and seller/products cards with slug, title, rating, seller

Analyticscategories, product-index

categories and product-index rows: url, id (slug), plus an honest total

Inside the gateway

Same request lifecycle as every other /v1 platform endpoint. G2 is not a sidecar.

Edge receives the call

Next.js catch-all routes into the Hono social API. We mint a request_id, authenticate the key, then enforce rate limit (600/min) and concurrency (50 in flight per key).

Validate, then debit

Registry lookup finds g2/product (or reviews, category, seller). Required params and format checks run first. Invalid input returns 400 with no charge. Valid calls debit the tier cost atomically before upstream work.

Cache or fetch

A deterministic cache key is built from platform plus resource plus params. Hit: return immediately, credits_used = 0. Miss: live public catalog read. Retries on 5xx/network with a circuit breaker if the source is unhealthy.

Normalize and return

Upstream JSON is mapped to commerce archetypes (Product, ProductList, ReviewList, Author, Analytics), validated against the canonical Zod schema, then wrapped in the success envelope and logged for billing audit.

Billing rules that matter in production

No write, ranking-submit, or vendor-dashboard routes

How we get the data

G2 is public software-catalog data. We normalize it into the SocialCrawl commerce schema so your code does not learn a second review-site SDK.

What G2 is for this API

Public software product pages, written reviews, category browse, vendor profiles, and a product URL index. Read-only. No vendor-dashboard or ranking-submit access.

How SocialCrawl reaches it

Product, reviews, category, seller, and index routes are read live from public G2 pages. One SocialCrawl key covers all of them.

What leaves our edge

A unified JSON envelope with Product, ProductList, ReviewList, Author, and Analytics archetypes shared across commerce platforms.

What we do not ship live

No vendor login, review submission, or paid-placement tools. No private G2 seller metrics.

1 / 5credit ladder for taxonomy vs product/reviews

Software catalog research, review mining, and vendor mapping

Callers start from a slug, a category, or the product URL index, then fan out to product and reviews. Product and reviews at a flat 5 credits, category taxonomy at 1, one key across SocialCrawl.

Product and taxonomy reads are typically a few seconds on live miss. Cold catalog queries can run longer.

Use case examples

Common ways teams put this data to work, and the stack each one tends to run.

Category researchers

Python, notebooks, BI

categories then category, then product for shortlists of software slugs.

Voice-of-customer teams

Node, warehouses

Pull reviews by slug for competing products. Advanced tier, cache friendly on repeats.

Vendor intel

Comparison

How does SocialCrawl compare to DIY G2 scraping for G2 data?

Same G2 data, two very different paths. Auth, rate limits, schema, and cost, side by side.

Feature	SocialCrawl	DIY G2 scraping
Authentication	One x-api-key, sign up and call	None, but you manage proxies and anti-bot evasion yourself
Setup	GET /v1/g2/product then /reviews with the same slug	Headless browser, proxy pool, HTML parsers, and retry logic to build
Response schema	Unified Product and ReviewList JSON shared with 64 other platforms	Raw HTML you parse. Selectors break when G2 redesigns
Pricing	5 credits per product or review pull, 1 credit for the category dump; 100 free credits, no card	Proxy and compute costs plus ongoing engineering time
Data coverage	Product pages, written reviews, category taxonomy, seller portfolios, and a paged product URL index	Whatever your parser extracts before the markup changes
Maintenance	Upstream changes absorbed by SocialCrawl	You fix the scraper every time the page structure shifts

FAQ

Find answers to frequently asked questions about SocialCrawl's API, pricing, and capabilities.

How do I scrape G2 product data with an API?

SocialCrawl provides 7 G2 endpoints. Call GET /v1/g2/product with a G2 slug (postman) or the full product URL to receive name, description, star rating, review count, categories, seller, pricing plans, features, and alternatives as unified JSON. Then GET /v1/g2/reviews with the same id for written reviews.

What data does the SocialCrawl G2 API return?

Product returns one software listing: title, rating, review count, categories, seller, plans, features, alternatives, and media. Reviews returns written review text with star rating and reviewer context, 10 per page. Categories returns the full taxonomy. Seller and seller/products cover vendor profiles and their product portfolios. Product-index pages G2 product URLs, 100 per call.

How much does the G2 API cost?

Product, reviews, category listings, seller, seller/products, and product-index cost 5 credits (advanced tier) per live miss. The category taxonomy dump costs 1 credit (standard tier). Cache hits cost 0. Empty or not-found results are refunded. New accounts get 100 free credits with no credit card required.

Is scraping G2 reviews legal?

SocialCrawl reads only publicly available G2 product and review pages, the same content anyone can see by visiting the URL. You are responsible for ensuring your use case complies with G2's terms of service and applicable data protection laws. SocialCrawl operates under a documented GDPR legitimate-interest framework: public, logged-out data only, no credential use, short-lived caches (2 to 30 minutes) with no persistent store, and a public opt-out channel for anyone whose public info appears in responses. Full details: socialcrawl.dev/legal/public-data-notice.

Does G2 have an official API I should use instead?

G2's own API is partner-gated and aimed at vendors managing their own product profiles, not at reading the public software catalog. SocialCrawl covers the public reads that API does not: product pages, written reviews, categories, sellers, and a paged product URL index, in the same Product and ReviewList schema as Amazon, Walmart, and Trustpilot.

What is the best G2 scraper API?

SocialCrawl is a strong pick for software-catalog work: product detail and written reviews for 5 credits, a full category taxonomy for 1 credit, plus seller portfolios and a paged product URL index. No proxies or headless browsers to maintain, and 100 free credits start you off without a card.

Is there a G2 data API?

Yes. SocialCrawl is a G2 data API for public software products and reviews. 7 endpoints cover product detail, written reviews, category browse, the category taxonomy, seller profiles, seller product lists, and a paged product URL index. Signup includes 100 free credits.
