The data

G2 data,
ready to work with.

A software comparison needs more than one aggregate number. G2 product records can include a name, category, source-reported rating and review count; the reviews operation returns individual responses in its own window. Categories help you discover products, while seller records connect a company to its returned portfolio. The Postman example shows fields from one recorded product response, with no claim that Monocrawl evaluated the tool. Preserve the category, source URL and collection date beside each score. Monocrawl exposes the supported public G2 records as JSON, leaving your team to decide which review evidence and criteria matter for a shortlist.

G2 API questions,
answered.

Comparing providers for G2 data?
G2 data APIs compared

Is a G2 rating Monocrawl’s recommendation?

No. The rating and review count are source-reported fields from G2. Read individual review records and apply your own comparison criteria.

Does a product review response include every review?

No. It is the returned review window for a product. Check its continuation and do not treat one page as a complete review archive.

What G2 operations can I use?

The catalogue shows 7 currently available operations with their individual prices. Open an endpoint for its accepted inputs, returned fields and limitations.

How much does the G2 API cost?

Start with 150 free credits. Paid subscriptions start at $29 per month for 10,000 credits, before applicable tax. Each operation has its own price. Check the endpoint reference for variable charges. Compare plans

How do I authenticate requests?

Use your Monocrawl API key in the x-api-key header. The endpoint reference lists any additional inputs needed for the operation. Authentication guide

What request limits apply?

Limits depend on your Monocrawl plan. The Free account ceiling is 600 requests per minute and 50 simultaneous requests. Endpoint capacity and Free daily protections also apply; these ceilings do not guarantee source throughput. Read the limits guide

What should I know about G2 coverage?

A G2 score is source-reported and can change; it is not Monocrawl’s evaluation of a product. Returned reviews and category pages are windows of the source, not a complete market census.

Is Monocrawl affiliated with G2?

Monocrawl is an independent service. Third-party names identify data sources and do not imply a partnership or endorsement.
