LinkSquares Metadata and Smart Values API

openapi: 3.0.3
info:
  title: LinkSquares Account Metadata and Smart Values API
  description: 'The LinkSquares API is the public REST API for the LinkSquares AI-powered contract lifecycle management (CLM) platform. It spans two products. Analyze exposes processed agreements plus the metadata, Smart Values, terms, types, tags, and parent/child hierarchy extracted from them, and lets you import DOCX/PDF documents for AI processing. Finalize lets external systems retrieve templates, create draft/intake/request agreements, and retrieve and approve tasks. All requests authenticate with an API key passed as an `x-api-key` header; the same token is shared across Analyze and Finalize. API access is gated to LinkSquares customers and keys are self-managed by Administrator users.


    GROUNDING NOTE: The Analyze paths in this document (under /api/analyze) are CONFIRMED against the public LinkSquares API Overview and Analyze API Sample Use Cases help-center articles, including live cURL examples. The Finalize paths (under /api/finalize) are MODELED from the capability-level descriptions in the LinkSquares API Overview - LinkSquares documents that Finalize can retrieve templates, retrieve and approve tasks, and create agreements, but the concrete request paths are behind the customer-gated API reference and must be confirmed before use. Request and response schemas throughout are modeled from documented behavior and examples, not copied from an official OpenAPI definition.'
