Text Similarity Search API

What it does

Text Similarity Search compares two strings and returns a similarity score between 0 and 1. Send a source string and a target string in the request body, then get back data as a floating-point score rounded to 3 decimal places.

Use Text Similarity Search when you need to measure how closely two pieces of text match without doing a full semantic analysis. It works well for duplicate detection, fuzzy matching, near-duplicate content checks, and simple comparison tasks in search or review workflows.

The response is intentionally compact: one numeric score that you can sort, threshold, or log. That makes it easy to plug into systems that need a quick similarity check for user-submitted text, product titles, tags, or short descriptions.

If you need a lightweight way to compare strings and make a yes/no or ranked decision from the result, Text Similarity Search gives you a direct score you can use immediately.
