The Problem
The IRC is the most cross-referenced legal document in America. Current tools treat it as flat text. They search keywords. They can't traverse cross-references, detect exceptions, or map dependency chains. Every missed link is a missed deduction — or a compliance risk.
Keyword search is blind
Searching "199A" returns the section. It doesn't show you that 199A(d) references 469, 170, and a dozen other sections that modify the deduction. You get a page, not a map.
Cross-references are invisible
Section 162 references 274, 280A, and 195. Section 280A references 162 back. These circular dependencies create traps that flat-text tools can't surface.
Exceptions hide in plain sight
"Except as provided in subsection (d)" — buried 3 levels deep. A human might miss it. A graph traversal finds every exception path automatically.
Capabilities
Graph Traversal, Not Keyword Search
Every query traverses the actual relationship graph. Ask about Section 199A and get the full dependency tree — cross-references, modifications, exceptions, and downstream effects — not a list of keyword matches.
BFS
Breadth-first
DFS
Depth-first
SP
Shortest path
Cross-Reference Mapping
5,478 edges map every "as defined in," "except as provided," and "subject to" across the IRC. See how sections depend on, modify, and override each other.
Exception Detection
Automatically surfaces exception paths and carve-outs. Never miss the "except as provided in subsection (d)" buried three levels deep.
Natural Language Queries
Ask in plain English. The API translates your question into a Cypher graph traversal and returns structured results with relationship context.
REST API Access
Authenticated REST endpoints on port 8084. X-API-Key auth. Search, document retrieval, domain taxonomy, team feeds, and metrics — all JSON.
Public Domain Data
Sourced exclusively from GovInfo USLM XML and eCFR — public domain, zero copyright risk. Redistribute, embed, or resell without licensing concerns.
Real-Time Updates
Graph stays current with IRC amendments. New sections and relationship changes are ingested as GovInfo publishes updates. No stale data.
Bulk Export
Export entire subgraphs, domain taxonomies, or filtered node sets as JSON. Build your own analytics, feed internal tools, or populate your own database with structured IRC graph data. Enterprise plans include full graph snapshots.
Live API
One REST call. Natural language in, structured graph data out. Every response includes the section, its title, cross-references, and edge count.

Pipeline
Step 01
GovInfo USLM XML and eCFR data is parsed into structured nodes. Every section, subsection, and paragraph becomes a typed node in the graph. Public domain — zero copyright risk.
govinfo.gov/uslm/title-26
ecfr.gov/title-26
Public domain. No license required.
Step 02
NLP extraction identifies every cross-reference, exception clause, modification, and dependency. Each becomes a typed, directed edge in Neo4j. 5,478 edges across 1,133 nodes.
Step 03
Natural language questions are translated to Cypher graph traversals. The API returns structured JSON with the section, cross-references, edge counts, and relationship types. Sub-50ms response times.
Step 04
Feed graph data into your tax software, compliance platform, or research tool. Bulk export entire subgraphs. Build internal products on top of structured tax intelligence without maintaining the graph yourself.
