Lex Machina
Lex Machina is a legal analytics platform owned by LexisNexis that transforms raw court documents and dockets into structured datasets so litigators, corporate legal teams, insurers, and judges can make data-driven decisions about cases, courts, judges, lawyers, parties, and damages. The platform covers all 94 federal district courts, the 13 federal courts of appeals, the PTAB, the ITC, bankruptcy courts, and a growing list of state courts (with 18M+ additional state cases for party analytics), and tracks 8,000+ judges, 6,000+ expert witnesses, 146M+ counsel mentions, and 149M+ party mentions across 10M+ cases and 45M+ documents. Lex Machina exposes its Legal Analytics through a public Litigation Analytics API (OAuth 2.0, JWT bearer tokens) at api.lexmachina.com with synchronous Python and Node.js client libraries plus an A2A (Agent-to-Agent) agent for AI/agent integrations. Practice area coverage includes Antitrust, Bankruptcy, Commercial, Consumer Protection, Contracts, Copyright, Employment, ERISA, Insurance, Patent, Product Liability, Securities, Tax, Torts, and Trademark litigation. Lex Machina was founded in 2010 as a Stanford University Law School spin-out and was acquired by LexisNexis (RELX) in 2015.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Lex Machina the way a machine reads it — 52 machine-readable artifacts across 21 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Lex Machina scores 41.6/100 (thin), with a separate agent-readiness read of 41/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

APIs 21
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Security Posture 4
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
