SEO APIs.
An SEO API lets software read and act on search performance data programmatically — checking where a page ranks, auditing technical health, generating metadata, or pulling backlink and keyword figures — without anyone opening a dashboard. The alternative is scraping search results yourself and owning that scraper forever.

ApyHubVerifiedHosted on ApyHubAnalyze AI Search Performance API
AI Search Analytics helps you measure how a brand or domain appears in AI search results. Send a target and source, and get back brand matches, prompt data, and visibility metrics you can use to track presence across AI engines. Use the discovery endpoint to find brands associated with a URL, domain, base domain, or full URL. For prompt analysis, query by target brand or by brand name and receive a dated response with totals plus a prompts array. Each prompt includes the prompt text, its type, the answer text, any links, and volume. You can sort by volume, type, or snippet length, and filter by volume, keyword count, character count, and multi-keyword inclusion or exclusion. For performance tracking, the overview endpoints return summary metrics and monthly time series for AI traffic, link presence, organic traffic, overall traffic, and average position. Use the aggregated view to compare performance across engines, or the leaderboard endpoint to compare a primary target against up to 10 competitors and see share of voice, link presence, and brand presence by engine. Build reporting dashboards, monitor competitor visibility, or audit how often your brand is cited versus linked in AI-driven search experiences.
Analyze Backlinks API
Backlinks Analyzer helps you inspect the backlink profile of a domain, host, or URL. Send a target and get counts, referring domains, referring IPs, anchor text breakdowns, authority scores, and backlink history back in JSON or XML. Use it to measure link acquisition, audit backlink quality, or compare pages during SEO reviews. The service supports both single targets and batch requests on several endpoints, so you can pull summary metrics for a site, then drill into the exact backlinks, refdomains, anchors, and indexed pages that make up those totals. You can also filter results by mode, limit, ordering, date range, dofollow or nofollow status, link type, anchor type, and URL patterns on the history and all-backlinks endpoints. For larger exports, the API returns a task ID and task status so you can poll for completion and download the generated .csv.gz file when it is ready. Backlinks Analyzer is a fit for SEO dashboards, competitive analysis, link monitoring, and automated reporting where you need structured backlink data instead of manual exports.
Audit Website SEO API
Website Audit lets you create, inspect, and manage site crawls for SEO and technical health checks. Send a domain and crawl settings, then track the audit as it moves through queued, processing, and finished states. Use the standard audit endpoint for an HTML crawl or the advanced audit endpoint when you need JavaScript rendering. Both accept a domain and an optional title, plus crawl settings such as maxpages, maxdepth, checkrobots, sourcesitemap, sourcesubdomain, ignorenofollow, ignorenoindex, and crawl limits like maxreq, maxsize, maxredirects, minwords, maxtitlelen, and maxdescriptionlen. The create endpoints return an id you can use across the rest of the API. Once an audit exists, fetch its status, full report, crawl history by date, crawled pages, found links, issue pages, or the issues for a specific URL. The list endpoint returns audit metadata such as url, title, status, stats, prevstats, lastupdate, and error; the report endpoint returns sectioned results with scorepercent, totalerrors, totalwarnings, totalnotices, and totalpassed. Website Audit is useful for scheduled SEO monitoring, release checks before publishing, and comparing crawl changes after fixes. You can also recheck an audit in standard or advanced mode.
Get SERP Results API
SERP Results Classic lets you submit search-result tasks, retrieve task status and results, and fetch the raw HTML dump for a completed task. It also includes a location lookup endpoint for resolving supported search locations. Send a task with an API key and a request body that can include tag, query, device, locationid, pingbackurl, languagecode, and searchengine. The task endpoints let you create a job, then poll by taskid to get the result or an advanced result payload when you need deeper SERP data. If you need the original page source for analysis or debugging, use the HTML dump endpoint with the same taskid. Use SERP Results Classic when you need programmatic search engine data for rank tracking, keyword research, competitor monitoring, or QA on location-sensitive search queries. The locations endpoint accepts q, include, and countrycode so you can narrow down supported search locations before submitting a task. This service is a fit when your workflow depends on Google-style search results and you want to automate collection, webhook delivery via pingbackurl, and post-processing from a task-based API.
Research Keywords API
This collection of endpoints is designed for comprehensive keyword analysis and discovery. Use these requests to retrieve performance metrics for large lists of keywords or to generate new keyword ideas based on a seed term. This folder is divided into two main categories: Bulk Keyword Metrics Export Keywords Metrics: Submit a list of up to 5,000 keywords to get detailed data points for each, including search volume, CPC, competition score, keyword difficulty, and historical search volume trends.
