Local SEO API
The local search stack behind one REST API. Sync listings to 70+ directories including Google Business Profile, Facebook, Apple Maps, Yellowpages, and Bing Places. Manage reviews and social media, run geo-grid rank checks, and pull presence and reputation analytics. One key, one auth header, one response schema across the whole platform.
// One key for the whole local SEO stack
const headers = {
'Authorization': 'API your_api_key',
'Content-Type': 'application/json'
};
const res = await fetch(
'https://api.synup.com/api/v4/locations',
{ headers }
);
const { data } = await res.json();
// From here, drill into any sub-resource:
// /listings/premium -> listing sync status
// /reviews -> reviews & ratings
// /rank-grid -> geo-grid rank
// /analytics/google -> profile analyticsEverything local search needs, behind one API
Most teams wire together three or four vendors to cover local: one for listings, one for reviews, another for rank tracking, something else for analytics. Each has its own auth, its own data model, and its own failure modes.
Synup puts the whole stack behind a single REST API. Authenticate once with an API key, and the same response schema covers listings across 70+ directories, reviews from every connected source, geo-grid rank reports, and profile analytics. Anything you can do in the dashboard is callable from the API, webhooks fire on upstream changes so you don't poll, and the same surface is exposed to AI agents through Synup MCP.
Four APIs, one platform
This page is the front door. Each part of the stack has its own reference, with full endpoints, payloads, and code.
Listing Management API
Sync a location once and it propagates to Google Business Profile, Apple Maps, Bing Places, Facebook, voice assistants, and AI search surfaces. Detect duplicates, read AI visibility scores, and manage rich attributes.
Explore the Listing Management APIReview Management API
Pull reviews from Google Business Profile, Facebook, Trustpilot, and a long tail of industry sources through one interactions schema. Post replies straight to the source, run sentiment, embed widgets, and trigger campaigns.
Explore the Review Management APILocal Rank Grid API
Local rank isn't one number. Run a keyword across a grid of points around a location and get a rank at each, so you can see where visibility falls off block by block. Schedule sweeps and rebuild the heatmap from raw points.

Profile analytics for Google, Bing, and Facebook: views, clicks, calls, and direction requests. Rank distribution and keyword performance over time. AI visibility scores against ChatGPT, Gemini, Perplexity, and Copilot. All in normalized JSON.

AI search visibility
Field-by-field similarity scores for what ChatGPT, Gemini, Perplexity, and Copilot know about a location against your source data, with the mismatches flagged.
Geo-grid rank, not a single pin
Per-point ranks across a grid so you can see real-world rank variance, not a city-level average that hides where visibility actually drops off.
One schema for the whole stack
Listings, reviews, rank, and analytics return one shape behind one key. No reconciling three vendors' formats in your pipeline.
Built to run in production
99% uptime on the platform behind 1M+ locations. Webhooks instead of polling, so listing status changes come to you.
Local marketing for AI agents
Plug Synup into your editor or assistant of choice and let the agent do the click-work. Locations, reviews, rankings, posts — same surface area as the dashboard, just exposed as tools.
