Originality.ai API Integration

Overview

Originality.ai scores text for AI authorship and checks it for plagiarism through a credit-based HTTP API. Scans are billed in credits that grow with word count, and the API key is tied to a paid account.

• Base URL: https://api.originality.ai/api/v1
• Auth: X-OAI-API-KEY header
• Docs: https://docs.originality.ai (the current reference is labelled "Version 3" and lists scan, batch-scan, scan-url, credit-balance and scan-results; the older v1 reference is still published)
• Rate limit: the account-level limit is not stated in the docs pages that could be read; Microsoft's connector lists 100 calls per 60 seconds, so throttle and retry on HTTP 429.

The exact field names of the v3 endpoints could not be fetched when this page was last refreshed (the docs site blocks automated clients). The parts below are confirmed by the v1 endpoint, third-party connectors and the docs index; check the field list in the docs before relying on anything not shown here.

Instructions

Authentication

Keep the key on the server only (ORIGINALITY_API_KEY) and send it as X-OAI-API-KEY. Never ship it to browser JavaScript. Avoid a double slash in the path (/api/v1//scan/ai fails).
