I built an all-in-one Social Media Toolkit API — 8 tools in one endpoint set

A developer created an all-in-one social media toolkit API with 8 tools, including username availability, hashtag generation, and engagement rate calculation. The API is now live on RapidAPI with a free tier. Engineers can use this API to simplify their social media-related projects. To get started, use the provided endpoints and follow the example usage. The API is built using Node.js, Express, and Upstash Redis, and is designed to be fast, scalable, and easy to use.
