Protégé Legal Data API

Key Features and Functions include:

Integration of AI-Powered Legal Assistance
Protégé’s personalized AI capabilities—such as conversational search and insights—can be embedded into firm intranets, client portals, practice-area tools, and bespoke applications. The API detects when user queries warrant LexisNexis content or firm knowledge and returns relevant, authoritative responses.

Content-Aware Query Handling
The API integrates content-aware intelligence that analyzes user input and triggers appropriate retrieval of LexisNexis content alongside relevant firm documents, helping users find grounded legal information in context.

Enterprise-Grade Security & Governance
Supports modern security measures including OAuth 2.0 authentication, role-based access control, audit logging, and firm-wide rate control to meet privacy, compliance, and governance requirements.

Personalization & Contextual Response Generation
Protégé tailors outputs based on individual roles, practice areas, workflow preferences, and task context, producing dynamic prompts and AI-assisted results tailored to legal professionals’ needs.

Developer-Friendly Endpoints
API endpoints are designed for integration without the need for custom training, tuning, or bespoke model management, delivering fast access to Protégé services within workflows.

Additional API Solutions within the Lexis Ecosystem
The Lexis API portfolio includes a range of complementary APIs (e.g., legal content search, alerts, Lex Machina analytics, entity resolution tools) that can be used alongside Protégé for enriched legal application development.
