What's in the API
Hybrid retrieval, tuned for tax
Most relevant cases first. Filter by section, court level, jurisdiction, date range, or outcome — the API does the heavy lifting so your product can show the right answer in milliseconds.
Citations + outcomes built in
Every result links to its citation graph and statutory references. Outcome inferred where the judgment supports it. No post-processing required.
Always current
The corpus is regularly refreshed — new judgments are ingested, citations re-linked. You always query the latest version. No stale indices.
Bundled in Pro+
Citator — full case-citation graph with treatment classification
The kind of citation graph legacy legal databases charge ₹50K-1L per seat per year for. Bundled with our Pro tier at ₹12L/month flat — unlimited users, unlimited downstream customers. Same-day access.
Treatment classification
Followed, distinguished, overruled, referred, explained, approved, disapproved — for every citation, with the supporting paragraph extract.
Outgoing + incoming edges
See which cases a judgment cites, AND which later judgments cite it back. Filter by treatment + court level.
Graph API + visualization
/citation-graph?depth=2 returns the full neighbourhood as nodes + edges JSON. Built-in visualization in the search UI.
Bundled in Pro+
Outcome Predictor — fact pattern → win-probability + precedents
Submit a free-text fact pattern. Get back a calibrated assessee win-probability, the precedents driving the prediction, and a factor breakdown by court tier. Production-ready REST endpoint. Pro tier and above.
Predicted win-probability
Aggregated from the most similar judgments, weighted by court tier and recency. Returns a calibrated 0-100% probability with a separate confidence score.
Supporting precedents
Every prediction ships the top 10 most similar precedents inline — citations, similarity scores, outcome labels — so your team can audit the call.
Factor breakdown
Signed contributions per court tier (Supreme Court, High Court, ITAT, GSTAT, AAR) plus the section-level historical win-rate baseline when a section is supplied.
Business plan and above
Time-machine — query the law as it stood on any past date
Pass as_of_date=YYYY-MM-DD on any caselaw query and get back only the judgments that existed (and were not yet overruled) on that date. Forensic accountants, audit defense, litigation strategy: reconstruct the legal landscape your client was working with.
Audit defense
“At the time of filing, the law as understood was…” — back the position with the precedents available on that date.
Tribunal-friendly
Cite only the cases that existed at the time of the assessee’s filing. The corpus filter does it; you don’t have to vet every result manually.
Overrulings respected
Judgments overruled before your as-of date drop out of the result set. The citator (Pro+) feeds the time-machine (Business+).
