G2

G2 is the world's largest B2B software marketplace, built on more than three million verified peer reviews and used by over 100 million software buyers a year. The G2 API provides programmatic access to G2's product catalog, category taxonomy, vendor records, reviews, badges, Grid reports, buyer intent signals and competitive intelligence. The v2 REST surface is a JSON:API contract of 62 operations served from data.g2.com, alongside a separate Data Solutions API for enriched flat-structure review data and a first-party remote MCP server at mcp.g2.com that exposes 21 tools to AI agents over OAuth 2.0. Authentication is by Developer Portal account token or OAuth 2.0 authorization code with PKCE, and most data surfaces are gated by subscription entitlement.

G2 publishes 29 API contracts indexed on the APIs.io network, including Buyer Intent API, Categories API, Chat Gpt Plugin API, and 26 more. Tagged areas include B2B, Software Discovery, Software Reviews, Buyer Intent, and Market Intelligence.

The G2 catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

G2’s developer surface includes authentication, documentation, developer portal, signup flow, pricing, legal docs, support, and 46 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Data Marketplaces (data providers on cloud data platforms)	builds-on	35.6	-	-
Reviews, Ratings and UGC (review platforms and who integrates with them)	builds-on	35.6	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
