G2 API pricing, reviews API access, documentation and tokens
G2 publishes no price for its API. In G2's own FY26 pricing guide the row Reviews API Access is marked in the Enterprise column only, and Enterprise is quote based. The only numbers G2 prints anywhere are Free at $0 and Starter at $299 a month or $2,999 a year, and Starter is restricted to new customers with 1 to 100 employees and fewer than 7 profiles. So the honest answer to "what does the G2 API cost" is that it costs whatever an Enterprise contract costs. Below is the full package table, what the API actually returns, and the two cheaper routes most teams should take instead.

Most people searching for the G2 API want G2 reviews on their own pages. That is a script tag, not an Enterprise negotiation. Our widget covers Google, G2, Trustpilot and direct reviews.
The question behind most G2 API searches
How much does the G2 API cost?
There is no per call price, no metered tier and no developer plan. G2 sells the API as a line item inside a marketing package, so the cost of the API is the cost of the package that carries it.
| Package | Published price | Reviews API Access | Review Collection APIs | Reviews Data Export |
|---|---|---|---|---|
| Free | $0 | No | No | No |
| Starter | $299 a month or $2,999 a year | No | No | No |
| Professional | Contact Sales | No | Yes | Yes |
| Enterprise | Contact Sales | Yes | Yes | Yes |
Prices and entitlements read from G2's FY26 external pricing guide, September 2026. Starter carries a footnote in that document: it is "only available to new G2 customers with 1-100 employees and <7 profiles", billed as a monthly plan with no contract. Add ons, including Buyer Intent and Data Solutions, are sold on Professional and Enterprise only, with the exception of G2 Clicks.
The distinction that decides your budget
G2 lists two different things with the word API in them, and they are not interchangeable. Review Collection APIs push requests out, letting you ask for a review from inside your own product, and they land on Professional. Reviews API Access, described in G2's guide as "customize how G2 Reviews are displayed on your website", reads reviews back out, and it is marked in the Enterprise column alone.
Nearly everyone searching for the G2 API wants the second one. That is why the answer lands where it does: the read side of the G2 API is an Enterprise entitlement, so there is no number to quote and no way to trial it. If a vendor tells you the G2 API starts at $2,999 a year, they are quoting the Starter package, which carries neither API.
G2 API documentation
What the G2 API is and where the docs live
G2 runs a real, documented API. It is just not a self serve one, and the public documentation is thinner than the developer portals you may be used to from Google or Trustpilot.
1
The base URL
G2 serves its API from data.g2.com/api/v2, with a Swagger reference published at data.g2.com/api/v2/docs. The documentation hub at documentation.g2.com points developers there as the authoritative source.
2
What it covers
G2 describes it as programmatic access to product, category and review data. That is broader than the buyer intent feeds G2 is better known for, and it is the endpoint family that the Enterprise entitlement unlocks.
3
How auth works
Through the G2 Developer Portal, which G2 documents as the place to create OAuth apps, manage tokens and authenticate your API requests. It is OAuth, not a static key pasted into a query string.
4
The real prerequisite
Entitlement, not code. The portal issues credentials against what your package includes, so the blocking step for most teams is commercial. There is no sandbox that lets you evaluate the review endpoints first.
G2 review syndication is a different door
If your searches keep surfacing "Reviews Powered by G2", that is the syndication partner program, not the API. It feeds G2 star ratings, review content, likes and dislikes, Q and As, videos and screenshots into third party marketplaces, and G2 names partners including ADP, UKG, CDW, Red Hat, Microsoft, SAP and AWS. You join it through Become a Partner.
It is worth knowing what it is so you can rule it out quickly. Syndication is built for a marketplace that wants to show reviews of other companies' software. If you are a vendor who wants your own G2 reviews on your own site, it is the wrong program and the sales cycle is long.
G2 against the other review APIs
G2, Trustpilot and Google review API access compared
Every review platform restricts API access to review content. They restrict it in different ways, and G2 is the only one of the three that will not tell you the price.
| G2 API | Trustpilot API | Google Places API | |
|---|---|---|---|
| Published price | None, Enterprise quote | Add on, on plans from $319 a month | $25.00 per 1,000 review calls |
| Lowest tier with review API | Enterprise | Plus, as a paid add on | Any, it is pay as you go |
| Reviews returned | Your own G2 reviews | Up to 100,000, full text | 5 per place, full text |
| Self serve signup | No | No, sales enabled add on | Yes, Google Cloud console |
| Spreadsheet export instead | Yes, on Professional | Yes, in the dashboard | No native export |
| Widget without any API | Yes, Starter and above | Yes, TrustBox | No official widget |
G2 figures from its FY26 pricing guide. Trustpilot and Google figures carried across from our Trustpilot API and Google Places API pages, checked at source. The pattern is consistent: the platform that most wants to be your system of record is the one least willing to hand you the data.
Decide before you call sales
Do you actually need the G2 API?
Four reasons teams go looking for it, and the honest route to each. Only one of them justifies an Enterprise conversation.
You do not need the API
You want G2 reviews on your website
This is the most common reason people land here and the most expensive way to solve it. G2's own Review Display Widgets are on Starter and above, and a third party widget renders G2 reviews with no token and no quota. Paying for Enterprise so a testimonial section can render is a large amount of money for a script tag.
Try the export first
You want your G2 review data in a warehouse
G2 lists Reviews Data Export, a spreadsheet containing all G2 review response data, on Professional and Enterprise. For quarterly reporting or a BI dashboard that refreshes on a schedule, a scheduled export usually does the job the API was going to do, one tier cheaper.
That is the other API
You want review requests inside your own product
Review Collection APIs, which let you ask for a review inside a customer's experience, sit on Professional and Enterprise. This is a genuine integration case and it is the one API entitlement you can reach without Enterprise. It writes requests out; it does not read reviews back.
Enterprise, and expect a negotiation
You are building a product on top of G2 data
If your product itself depends on G2 product, category and review data, the Reviews API Access entitlement is the only legitimate route and it means an Enterprise contract. Budget for a sales cycle rather than a signup form, and get the rate limits in writing before you design around them.
Being straight with you
Where ReviewJet fits, and where it does not
We sell review software, so you should know exactly what we do and do not cover before you weigh anything on this page.
What we do not do
We are not a replacement for a G2 Enterprise contract. If you need the raw G2 API, with G2's own endpoints and entitlements, you have to buy that from G2 and nothing here changes that. We also do not sell a public API of our own, and we are not going to imply otherwise.
What we do
We collect, monitor and display Google, G2, Trustpilot and direct reviews through one embeddable widget, and we run the request sequences that grow how many reviews you have in the first place. Flat pricing from $24 a month. If the job is "our G2 reviews should be visible on our site", that is the part we solve without a token.
