Listings API is a REST API service designed for businesses and developers that need to manage local business listings, reviews, and posts across multiple online directories from a single integration point. The API provides a unified interface for listings management, local citations, review monitoring, and Google Business Profile management. It includes typed SDKs and a hosted MCP server, allowing users to build local SEO functionality into their own products under their own brand without manually integrating with each directory individually. The core workflow begins with creating a location as a single source of truth, including name, address, hours, and categories. A single API write operation fans out this information to major directories including Google, Apple Maps, Bing, Yelp, and Facebook, maintaining consistent NAP (Name, Address, Phone) data across all platforms. The API supports OAuth authentication for businesses to connect their own profiles, allowing the system to publish and read on their behalf. Each citation is confirmed as live through a syncStatus that moves to SYNCED and through listing.submission webhooks. Typical use cases include onboarding a business once and publishing to every major directory, connecting Google and Facebook profiles, and receiving confirmation that each citation is live. The API serves as an infrastructure layer, while the product it powers remains under the user's own brand, UI, and customer relationship. The API handles the partnerships, rate limits, and synchronization plumbing required to maintain listings across multiple platforms. Pricing starts at 99 dollars per month with a 14 day free trial and cancellation available at any time.
