Lexion

Lexion is an AI-powered contract lifecycle management (CLM) platform that centralizes agreements in an intelligent repository, extracts key terms and dates, and drives no-code intake and approval workflows across legal, sales, procurement, finance, and HR. Founded in 2019 out of the Allen Institute for AI, Lexion was acquired by Docusign in May 2024 for ~$165M and folded into Docusign's Intelligent Agreement Management (IAM) platform and Docusign Navigator. Lexion exposes an enterprise, sales-led integration API but does not publish a self-serve, openly documented public API.

Lexion publishes 4 APIs on the APIs.io network, including Contract Repository, Extraction & Insights, Workflows, and 1 more. Tagged areas include Contract Management, CLM, Artificial Intelligence, Legal Tech, and Document Extraction.

Lexion’s developer surface includes documentation, engineering blog, and 7 more developer resources.
