We just shipped the LLM Mentions API. One call to `POST /v1/seo/ai/llm-mentions` searches a pre-indexed corpus of 253M+ prompts and answers from ChatGPT and Google AI Overview. Pass any domain or keyword as the target and get back every AI answer that cites it — with the full answer text, the sources the LLM linked to, AI search volume per question, brand entities mentioned, and the fan-out queries the LLM derived from the original prompt. This is the cheapest, fastest way to audit your AI visibility and competitor citations without re-scraping the LLMs live for every prompt.
What's new
- Search 253M+ indexed ChatGPT + Google AI Overview prompts and answers
- Target any combination of domains and keywords (up to 10 per call)
- Per-question AI search volume with 12-month history
- Brand entities and fan-out queries extracted from every answer
- Cited sources with URL, title, and domain
- Filter by scope (`answer`, `sources`, `brand_entities`, `fan_out_queries`), search volume, date, and more
- Up to 1000 results per call; cursor-based pagination beyond 9000
- Same `yep_sk_` key, same `{ ok, data }` envelope, 6 h Redis cache
- $0.20 base + $0.002 per row returned — fractions of a cent per mention

What you can do with it
Track every prompt where your domain shows up as a source in Google AI Overviews and ChatGPT — and rank them by `aiSearchVolume` to see which AI questions actually drive demand. Reverse-engineer competitor visibility by querying their domain and reading the answers verbatim. Discover brand-adjacent questions you should be producing content for via the `fanOutQueries` field. Monitor mention share against named competitors using `brandEntities`. Build an internal AI visibility dashboard without rolling your own scraping pipeline.
Quick start
Pass an array of targets. Each target is either a `domain` or a `keyword`, with optional scope and filter modifiers.
curl -X POST https://api.yepapi.com/v1/seo/ai/llm-mentions \
-H "x-api-key: $YEPAPI_KEY" \
-H "Content-Type: application/json" \
-d '{
"target": [
{ "domain": "yepapi.com" },
{ "keyword": "seo api", "search_scope": ["answer"] }
],
"platform": "google",
"limit": 100,
"filters": [["ai_search_volume", ">", 100]],
"order_by": ["ai_search_volume,desc"]
}'Pricing
Dynamic — $0.20 per call plus $0.002 for each mention row returned. A request that returns 100 results costs $0.40. The minimum balance gate is $0.20, so you'll never get hit by a surprise charge on an empty query. Same prepaid balance as the rest of the platform, billed only on a successful 2xx response.
Limits and coverage
Up to 10 target entries per request, up to 8 filters, up to 3 sort rules. `offset` is capped at 9000; for deeper paging use the `searchAfterToken` returned in each response. `platform: "chat_gpt"` is US/English only — for multi-locale coverage use `platform: "google"` (Google AI Overview).
