Listings API

The local marketing API

Listings API turns local marketing into one REST API. Create a business location in a single call and publish it across Google Maps, Apple Maps, Bing, Facebook, and dozens of directories and AI answer engines. We handle every publisher integration, sync, and update. The same API aggregates reviews and lets you respond programmatically, publishes posts and offers to Google and Facebook (single or bulk), and returns per-publisher analytics for dashboards and reports. Built for developers: typed Python and Node.js SDKs, an interactive playground, a public OpenAPI spec, and a hosted MCP server so AI agents can manage locations conversationally. Built to be white-labeled: SaaS platforms, agencies, and marketplaces ship listings management under their own brand in days. Self-serve signup with a 14-day free trial from $99/mo at listingsapi.com every plan includes the full API surface.

Checksum AI

Your coding agent’s testing buddy

Checksum is an AI-native continuous testing platform built for engineering teams that are shipping faster than manual QA can keep up. It automatically generates, runs, and self-heals end-to-end and API tests on every pull request, all as standard Playwright code in your own repository. When a test fails, Checksum tells you whether it found a real bug or a stale test, then fixes the false failures so your suite keeps pace with your coding agents. This means you can trust your test suite, reduce flaky tests, and focus on building features instead of debugging test infrastructure. Checksum integrates seamlessly into your CI/CD pipeline and works with the tools you already use.
