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.
Lex Machina publishes 18 API contracts indexed on the APIs.io network, including Alerts API, Attorneys API, Authorization API, and 15 more. Tagged areas include Legal, Legal Analytics, Legal Tech, Litigation, and Litigation Analytics.
The Lex Machina catalog on APIs.io includes 1 Spectral governance ruleset.
Lex Machina’s developer surface includes authentication, developer portal, documentation, engineering blog, YouTube channel, support, and 26 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Government & Public Sector regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 75 points between them,
because the conditional facet above carries the other
25. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 75% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

It updates itself when the score changes. Paste this where you link to your API docs:

Agent readiness — checks not met, largest first (exact, from this profile):
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented) Ask about this →
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes Ask about this →
Rate-Limit Signaling+7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented) Ask about this →
Typed Event Surface+6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks Ask about this →
Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.
Not sure how this applies to your stack? Ask about any one item. Kin Lane reads every question, looks at your profile and your situation, and replies with what a fix would take — scoped to that one area, priced up front, yours whether you ship it or not. Ask a question →
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
