As answered by people managing Data Protocol and Onepostly.
Onepostly's answer:
Onepostly is one REST API for 9+ social platforms including X, Instagram, Facebook, Threads, LinkedIn, YouTube, TikTok, Pinterest, and Bluesky. Developers connect accounts once and then publish, schedule, manage media uploads, read insights, handle engagement, and receive webhooks from a single endpoint. It also works natively with AI agents via MCP, so Claude, Cursor, or any MCP client can publish and schedule across platforms. Platform-specific OAuth flows, media rules, rate limits, and content formats are abstracted away.

Onepostly's answer:
Developers, SaaS products, agencies, marketing teams, and creators who need to add social media publishing and scheduling to their product or automate content workflows without building separate integrations for each platform. B2B and B2C.
Onepostly's answer:
Onepostly started from the same pain every developer hits - building one integration for X, then another for Instagram, then Facebook, LinkedIn, YouTube, TikTok, Pinterest, and Bluesky. Each has its own OAuth, media upload, character limits, and rate limits. Onepostly was built to solve that by providing one unified API that handles all platform differences so teams can ship social features in hours instead of months.
