Which sources AI answers cite: ranked domains with domain ratings, domain-type and page-type splits, and per-platform counts. Opt into `subreddits`, `timeseries`, and `competitorSources`; cap the domain list with `domainLimit`. `search` matches the cited domain before `domainLimit` is applied. To fetch specific domains, pass `domains` as a JSON array of hosts; `domainsTotal` still counts every cited domain. `timeseriesDomains` narrows the timeseries the same way, which otherwise carries every cited domain per day. Scope filters are described on [AI Visibility](https://snowseo.com/docs/api-reference/endpoints/ai-visibility.md). ## OpenAPI ````yaml GET /v3/ai-tracker/visibility/citations openapi: 3.0.0 info: title: SnowSEO API description: API documentation for SnowSEO version: 1.0.0 servers: - url: https://api.snowseo.com description: Production server security: - bearerAuth: [] - apiKey: [] externalDocs: url: https://snowseo.com/docs description: Find more info here paths: /v3/ai-tracker/visibility/citations: get: tags: - AI Tracker summary: Sources AI engines cite when answering about the brand description: >- Which sources AI answers cite for a team: ranked domains with citation counts and domain ratings, domain-type and page-type splits, per-platform citation and mention counts, and top sources.
