curl -X POST https://api.unifapi.com/geo/mentions/top-domains \ -H "Authorization: Bearer $UNIFAPI_KEY" \ -H "Content-Type: application/json"
Parameters
- X-Unifapi-Max-Creditsheader
- Optional maximum credit budget for this request. The gateway validates the required reservation before collection and rejects a lower cap without charging. Unused reserved credits are released after settlement. Omit to use your available balance.
- The parameter for this GEO operation. Use the URL-visible slug or id described in the docs.
- The parameter for this GEO operation. Use the URL-visible slug or id described in the docs.
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.
Response status codes
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. Incorrect Credit deductions caused by platform failures can be restored as billing corrections.
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.
Fields in the data object
A successful List domains most cited in LLM answers call returns one data object with these fields.
- enginestring
- locationstring
- languagestring
- totalsobject
- Mention metrics grouped across platform, location, language, source/search-result domains, and brand entities.
- resultsobject[]
- Top cited domains, one billable record each, with per-dimension breakdowns.

Search LLM mentions of a domain or keyword
Search an indexed corpus of ChatGPT or Google AI Overview answers. This does not execute a custom prompt. Includes answer text, sources and estimated AI search volume. Costs 10 credits per returned record, minimum 1,000 credits ($1). Reserves credits for limit (default 100) before collection and releases unused credits; no balance truncation. Failed requests are not charged.
List pages most cited in LLM answers
Rank the pages most frequently cited as sources in LLM answers for a target domain or keyword, with per-dimension breakdowns.
Aggregate LLM mention metrics by dimension
Aggregate LLM mentions of a domain or keyword across platform, location, language, source/search-result domains, and brand entities.
Compare LLM mentions across labeled groups
Aggregate and compare LLM mention metrics across several labeled target groups for side-by-side share-of-voice analysis.
Get monthly AI mention history
Return a monthly time series of AI mention counts and estimated AI search volume for a keyword or domain, from the indexed corpus for Google AI Overviews or US-English ChatGPT. This is not a replay of your custom prompt panel. Corpus coverage can change; estimated AI search volume is not observed traffic. Date windows start on 2025-08-01 and span at most 366 days. Monthly history costs a minimum of 500 credits ($0.50). The maximum credits are reserved before collection; unused credits are released. Failed requests are not charged. Allow at least 150 seconds for the response.
Get changes in AI mentions and search volume
Return the net change in AI mentions and estimated AI search volume for a keyword or domain per time bucket (day, week, month or year) — how much each bucket gained or lost against the one before — from the indexed corpus for Google AI Overviews or US-English ChatGPT. This is not a replay of your custom prompt panel. Corpus coverage can change; estimated AI search volume is not observed traffic. Date windows start on 2025-08-01 and span at most 366 days. Costs 10 credits per returned time bucket, minimum 1,000 credits ($1). The maximum credits are reserved before collection; unused credits are released. Failed requests are not charged. Allow at least 150 seconds for the response.
