Farasa Web API

Farasa ("insight") is the Arabic text-processing toolkit built by the Arabic Language Technologies group at QCRI, Hamad Bin Khalifa University, and offered free to registered users as a keyed web API. Six endpoints were confirmed live on 2026-08-30 by unauthenticated POST probes — segmentation, lemmatization, pos, ner, diacritize and spellcheck each returned 400 "invalid api key", while sibling module paths returned 404. The api_key travels in the request body rather than a header. No OpenAPI is published by the provider; the definition in this repo is DERIVED from QCRI's own Python/Java/JavaScript/curl samples plus those probes, and the success payload shape is deliberately left unasserted because it could not be observed.

Where this information came from

This is an independent, third-party profile of Farasa Web API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
