Statute API

The Lexcel Statute API is a statute-grounded question-answering service for US state law. It ships in two integration models on top of the same dataset.

Two ways to use it

Section titled “Two ways to use it”

Tools (free)

Raw REST endpoints your agent calls directly. List jurisdictions, read sections, search semantically, verify a quote. Your agent does the reasoning. Nothing to install: an OpenAPI spec and a key.

Answers (paid, by request)

One endpoint. Send a natural-language question with jurisdiction and date filters, stream back a cited answer. Our agent stack plans the retrieval and grounds the response. Not open for self-serve yet, contact us.

What both share

Section titled “What both share”
  • status — every section is flagged CURRENT, PENDING, or REPEALED. Your agent knows when a citation is live and when it has been superseded.
  • as_of — pass a date and get the section as it stood that day. Effective-date scoped, with version history.
  • Cited or nothing — every response includes at least one citation with section number, exact quote, and effective-as-of date. The API refuses to return a paraphrase without one.
