Includes software and services categories; parent labels are not inferred parent IDs. No query filters, counts of products, or pagination. The public G2 directory lists software and services categories. This operation takes no parameters and returns the full available directory page in its source order. Each `items` entry contains G2's numeric `id` as a string, URL `slug`, source `name`, displayed `label`, `parent_label` and `url`. The parent label is source text, not an inferred parent ID or a guarantee of a unique parent. Source URL casing and trailing hyphens are preserved. `total` counts returned category entries; it does not count products. `next_cursor` is null. The directory can change. This endpoint does not return products, rankings, filter counts or historical category snapshots. The adapter uses one fresh basic Firecrawl fetch of the exact public G2 page. Redirected, failed or inconsistent pages are rejected rather than treated as empty successes. A successful fresh request uses the documented SocialQuery price; cached responses and successful idempotent replays are free. ## OpenAPI ````yaml GET /g2/categories openapi: 3.1.0 info: title: SocialQuery API version: '2026-10-09' description: >- Documented requests for public-source records.
