"Rank tracker API" covers two different products. A tracked-project API reads rankings a vendor already checks and stores for your projects. A raw SERP API fetches a live results page on each call, and you store history and find your own position. The first is a reporting tool, the second a building block. The reviews below follow that split.
Disclosure: AY Rank makes this tool, so this entry describes our own product rather than an independent review.
The AY Rank app is a tracker for Google rankings and AI answers that you query from Claude, ChatGPT and other MCP clients. One point first: the AY Rank app has no public REST API for rank data. You reach your tracked Google ranks through its MCP server (keywords_list, rank_movers, keyword_detail, check_ranks) with a workspace key, or through the app and its CSV export. If you need tracked ranks over REST, pick SE Ranking, Keyword.com or Ahrefs. If you need a raw SERP endpoint for your own code, skip to entries 5 to 8.
The MCP route swaps a script for a question. keywords_list returns each tracked keyword with its Google rank in every market and device, plus 90 days of Search Console numbers. The same server answers what ChatGPT, Gemini, Perplexity, Claude, Google AI Overviews and Google AI Mode say about your brand. A small REST endpoint exists for content and calendar work, but it returns no rank data.

SE Ranking's Rank Tracker API is a REST interface to the positions SE Ranking collects for your projects. It returns daily positions, changes, the ranking URL, the full top 100, competitor positions and history for any date range as JSON.
You can also create projects, add keywords and trigger a fresh check with the recheck endpoint. It covers Google, Bing, Yahoo and YouTube, desktop and mobile, by country or city. An MCP server exposes the same endpoints to Claude.

Keyword.com's Rank Tracker API is a REST API (v2, bearer token) that returns position, best position, search volume, CPC, competition score, region and language for every keyword in your account. Endpoints live under app.keyword.com/api/v2/.
The pricing model is the reason to pick it. API access is in every plan with no credits, no per-call charges and no monthly call limits, so you pay for keywords, not requests. Tracking runs daily or weekly per project, with unlimited SERP history.

Ahrefs API v3 has a Rank Tracker section at api.ahrefs.com/v3/rank-tracker with six read endpoints: overview, SERP overview and four competitor reports. Management endpoints handle Rank Tracker projects.
Ahrefs' docs say Rank Tracker endpoints do not consume API units, while most other requests cost at least 50 units. If you already track keywords in Ahrefs, pulling them by API costs nothing extra.

DataForSEO's SERP API is a pay-per-task API that returns live results from Google, Bing, YouTube, Yahoo, Baidu, Naver and Seznam. It tracks nothing for you: you send keywords, it returns the page, you store positions.
Price depends on speed. One Google SERP of up to 10 organic results costs $0.0006 in the Standard queue (about 5 minutes on average), $0.0012 in the Priority queue (about a minute) and $0.002 in Live mode (about 6 seconds). Deeper checks cost more: a top-100 check is 10 SERPs.

Bright Data's Rank Tracking API is a SERP API for collecting organic and Google Ads keyword rankings from Google, Bing, Yandex, DuckDuckGo and Baidu. Results come back as raw HTML or parsed JSON, targeted to any country or city.
It bills only for successful requests. In asynchronous mode only the "send request" call counts, so collecting the response is free.

SearchApi's Google Rank Tracking API is a dedicated endpoint (engine=google_rank_tracking) that returns up to 100 organic results per search with no duplicates. It keeps the response small: positions plus rich result details such as sitelinks, snippets, video and images.

SerpApi is a search results API with separate endpoints for Google, Bing, Yahoo, Baidu, DuckDuckGo and many more. It is not a rank tracker, but you can find your position in the organic results. Its pricing page says a response counts as one search however many results it holds, and failed or cached searches are free.

If you want positions, history and competitors without writing a scheduler, pick a tracked-project API: SE Ranking, Keyword.com or Ahrefs for REST, or the AY Rank app if you will read ranks from Claude or ChatGPT. If you are building a product, or need checks on your own schedule, pick a raw SERP API: DataForSEO, Bright Data, SearchApi or SerpApi. Raw SERP is cheaper per check but you own storage and parsing.
Do the math before you sign. 500 keywords checked daily is about 15,000 checks a month. On DataForSEO's Standard queue that is about $9 for the top 10, or about $90 for the top 100, because each extra 10 results is another SERP. On Bright Data pay as you go, 15,000 requests is $22.50 before you confirm result depth. Tracked-project APIs flip this: Keyword.com and SE Ranking charge by keyword count, so call volume does not move the bill.
A Looker Studio dashboard, a cron job or your own app needs REST. A weekly review in Claude or ChatGPT works fine over MCP, which the AY Rank app, SE Ranking, Keyword.com and Ahrefs all offer. If the same stack also needs link data, our sister guide to backlink APIs compares them the same way.
What is a rank tracker API?
A rank tracker API returns keyword positions in search results as structured data, usually JSON. Some read rankings a vendor already tracks for your projects, others fetch a live results page on each call. Both let you put rank data in your own reports or code.
What is the difference between a rank tracking API and a SERP API?
A rank tracking API reads positions a vendor checks and stores for you. A SERP API returns one live results page per request and leaves storage to you. SE Ranking and Keyword.com are the first kind, DataForSEO and SerpApi the second.
Which rank tracking API is the cheapest?
For raw checks, DataForSEO's Standard queue at $0.0006 per Google SERP of 10 results was the lowest per-check price we read on 10 Nov 2026. For a tracked-project API, Keyword.com starts at $4/month for 50 keywords updated weekly, or $16/month for daily, with the API included. Your real cost depends on result depth and how often you check.
Does the AY Rank app have a rank tracking API?
No. The AY Rank app has no public REST API for rank data. You reach your tracked ranks through its MCP server, which Claude, ChatGPT and other MCP clients call with a workspace key, or through the app and its CSV export.
Can I check my rankings from Claude or ChatGPT?
Yes. The AY Rank app, SE Ranking, Keyword.com and Ahrefs all offer MCP servers that let an assistant pull your tracked positions. You add the server and a key to your MCP client, then ask in plain language.
Is there a free rank tracker API?
Several have free allowances. SerpApi gives 250 searches a month, Bright Data 5K requests a month, SearchApi 100 requests on sign-up and DataForSEO a $1 trial credit. For free tools that track AI answers rather than Google, see our list of free AI rank tracking tools.
Do rank tracking APIs cover Google AI Overviews?
Some do. SE Ranking tracks AI Overviews among 35+ SERP features, and DataForSEO returns AI Overview data for one extra base price per task. For tools built around AI Overviews, read our guide to AI Overview rank trackers.
