SEO API — Keyword Research, Backlinks, Rank Tracking & AI Search Visibility

Live27 SEO data endpoints

Muapi's SEO API covers keyword research, backlink analysis, rank tracking, Google & local SERP data, Google Business Profile data, YouTube SEO, and AI search visibility (AEO) — 27 endpoints in total, called through the same REST pattern as every other Muapi model: one API key, submit-then-poll, pay per call with no subscription. This page groups every endpoint by what it actually does and links straight to its playground page.

Classic SEO Data, Plus AI Search Visibility

The SEO API spans the same core categories developer tools like DataForSEO, Ahrefs, and SEMrush expose — keyword research, backlink analysis, rank tracking, and SERP data — plus Google Business Profile and YouTube SEO data.

It also covers a newer, genuinely different search surface: AI search visibility (AEO/GEO) — tracking how often a brand gets cited or mentioned by ChatGPT, Google AI Overviews, and other LLM-backed search products, and running live prompts against frontier models to see exactly what they say right now. As AI answer engines take a growing share of search traffic, this belongs alongside classic SEO in one API, not a separate product.

Frequently Asked Questions

What is Muapi's SEO API?

A single REST API covering 27 SEO data endpoints — keyword research, backlinks, rank tracking, Google & local SERP, Google Business Profile data, YouTube SEO, and AI search visibility (AEO) — all callable with one API key and pay-per-call pricing, no subscription.

What's the difference between Rank Track and Rank Track (Batch)?

Rank Track checks one keyword's position for a target domain against live Google organic results. Rank Track (Batch) does the same for up to 50 keywords in a single call, which is cheaper per-keyword for larger tracking workflows.

What is AI search visibility / AEO tracking?

AI Mentions and AI Mentions Metrics search for and analyze how often a brand, product, or domain is cited by AI platforms like ChatGPT and Google AI Overviews — the newer complement to classic SEO now that people search inside LLMs, not just Google. AI Response Query goes further and runs a live prompt across frontier LLMs (GPT-5, Claude Sonnet 4.5, Gemini) so you can see exactly what they say about a brand right now.

Do I need a DataForSEO, Ahrefs, or SEMrush account?

No. Muapi hosts the underlying data connections and bills per call from your existing Muapi credit balance — no separate vendor account, contract, or per-seat pricing.

How is pricing calculated?

Every endpoint is billed per call, from $0.001 (Google SERP, Rank Track) up to $0.05 (Backlinks, Domain Overview) depending on data depth. There's no subscription or minimum commitment — see each card above for its exact price.

What does a request look like?

POST a JSON body to https://api.muapi.ai/api/v1/{endpoint} (e.g. seo-keyword-research). You get back a request_id. Poll GET /api/v1/predictions/{request_id}/result until status is completed, then read the data from outputs.

Can I track local business rankings, not just organic search?

Yes — Local SERP tracks Google Maps and Local Finder map-pack positions, and the four Business Listings/Profile/Reviews/Updates endpoints cover Google Business Profile data directly.

Can I get SEO API access right now?

Yes. Sign up at muapi.ai, create an API key from your dashboard, and start calling any SEO endpoint immediately — no waitlist required.
