Documentation

Phrasit exposes its citation lookup and grammar check as JSON endpoints, and every tool ships as a copy-paste iframe. Both are free, no signup, no API key. This is the short reference for using them from your own site or script.

API reference

Two POST endpoints: citation metadata lookup from a DOI, ISBN, or URL, and grammar check via LanguageTool.

Request and response schemas, curl and fetch examples, rate limits.

Embedding tools

Drop any Phrasit tool into a Squarespace, WordPress, Notion, or LibGuide page with a single iframe.
