LocalCode API

LocalCode provides structured access to municipal code and ordinance context with a provenance-first model.

Developer Preview: The LocalCode API is currently available to design partners. These docs describe the draft v1 API contract and may evolve before general availability.

Our core principle is simple:

We do not just show the code.
We show where the law comes from.

​

Who this is for

• Product and evaluation buyers assessing trust, coverage, and integration fit
• Platform and API engineers building retrieval and monitoring workflows
• Data partners and legal-tech teams integrating provenance-aware legal data

What v1 Covers

The initial API scope is read-only and focused on:

• Jurisdictions
• Code sections
• Ordinances
• Legislative-chain relationships
• Source links for code sections
• Code-section-centric search

​

Provenance-First Fields

Where applicable, responses expose provenance metadata as separate fields:

• source_verification_status
• analysis_confidence
• official_source_url
• source_reference
• relationship_type

source_verification_status answers whether a source-backed claim is verified. analysis_confidence expresses model or parser confidence in extracted or derived relationships.

​

Authentication

All API requests use bearer authentication: Authorization: Bearer {LOCALCODE_API_KEY}
