List domains most cited in LLM answers · GEO API
Rank the domains most frequently cited as sources in LLM answers for a target domain or keyword, with per-dimension breakdowns.
curl https://api.unifapi.com/geo/mentions/top-domains \ -H "Authorization: Bearer $UNIFAPI_KEY"
This operation is part of the GEO API in the generative engine optimization category. It uses the same Bearer token, request tracing, error model, and billing envelope as every UnifAPI endpoint, so agents can switch between platforms without custom per-vendor glue code.
Use it when a workflow needs GEO public data but should still keep one API key, one account balance, and one predictable JSON contract across social, live public-data sources.
Common agent workflows
- Fetch canonical public GEO content for summarization, ranking, monitoring, or enrichment.
- Attach engagement, author, media, and source metadata to an agent workflow.
- Give an AI agent a stable GEO data source without building a per-platform integration.
- Normalize GEO responses into the same UnifAPI envelope used across the catalog.
Unified envelope, platform-native fields
- List-style responses return `data` as an array of top-level records plus optional `pagination` for continuation tokens or cursors.
- The operation has a 500 credits ($0.50) minimum charge, so `billing.records_charged` can be higher than the visible records returned.
- If the workspace balance cannot cover every result, the response can be truncated and `billing.truncated_due_to_balance` tells the caller why.
Billing
This operation charges 1 credit per billable record, with a 500 credits ($0.50) operation minimum. Public responses include billing metadata with credits charged, records charged, and remaining workspace balance. Platform-caused failures can be refunded.
Errors and retries
Authentication, validation, rate-limit, not-found, and provider errors use the unified UnifAPI error format. Agents should log `request_id`, retry only retryable failures, and treat invalid API keys, disabled keys, and expired keys as the same public `unauthorized` error type.
More GEO operations
Combine endpoints from the same platform, then join the results with other UnifAPI categories without changing authentication or response parsing.
