Postproxy is a unified publishing API for social networks that replaces individual platform integrations and handles platform-specific failures at publish time. It removes the operational mess by providing one stable publishing layer across platforms, addressing challenges like platform bureaucracy, account sprawl, inconsistent rules, and operational failures.

The API handles platform-specific endpoints, rate limits, and constraints automatically. It transforms content to match each platform's requirements and manages OAuth flows, token storage, and automatic refresh. Postproxy provides delivery guarantees with automatic retries, rate limit handling, quota awareness, and clear publish state reporting.

Integration involves three steps: getting an API key, connecting social media accounts, and publishing content via a unified API. The system validates content, applies platform rules, and ensures delivery through a single consistent endpoint.

Postproxy enables explicit publish states so users always know what succeeded, what failed, and why. Failures are handled by design with retries, rate limits, and quotas as first-class concepts. It allows scaling from ten to ten thousand items using the same deterministic logic.

The product is designed for developers who automate content at scale and fits into production-grade workflows like n8n. Use cases include generative content pipelines, CMS-driven social automation, multi-account posting, release announcements, multi-language posting, and AI-powered weekly digests.
