TextAI Pro: Lightweight REST API for Sentiment Analysis and Summarization

TextAI Pro is a lightweight REST API that delivers sentiment analysis and summarization without the overhead of large language models. It exposes two endpoints: POST /analyze returns sentiment ("positive/negative/neutral"), a confidence score between 0 and 1, top keywords, and word count; POST /summarize produces an auto‑summary and reports original versus summary length. The service is hosted on RapidAPI, where developers can sign up for a free BASIC plan that allows 50 requests per hour, upgrade to PRO for $9.99 per month with 1,000 requests per hour, or ULTRA for $29.99 per month with 10,000 requests per hour. Sample Python and JavaScript snippets show how to call the endpoints and parse the JSON response. The API was built to process bulk customer reviews, handling 50,000+ records per day at a fraction of the cost of OpenAI’s per‑call pricing. Use cases include review monitoring, content moderation, CRM enrichment, chatbot routing, and news sentiment tracking. The free tier requires no credit card, making it easy to experiment. The author invites feedback on additional endpoints that would be useful. The pricing table and usage limits are clearly documented in the RapidAPI page. The API is intended for developers looking for a cost‑effective, easy‑to‑integrate sentiment solution.
