Data you
can trace.
The Utsavs API reconciles public calendars with institutional closures and regional rules. Built for technical systems that require high-stakes date precision.
Developer Quickstart
01. Authentication
Every request must include an X-API-KEY header. Access is restricted to authorized partners.
02. Parameters
jurisdictionRequired. ISO 3166-1 alpha-2 country code (e.g., IN, JP, US).
dateRequired. ISO-8601 date string (YYYY-MM-DD).
purposeOptional. Context filter: travel, business, study, workforce, or logistics. Default: travel.
03. Response Schema
Our engine returns a materialized_record. This is a computed result based on the intersection of the date, jurisdiction-specific rules, and the chosen user purpose.
curl -X GET "https://utsavs.com/api/v1/intelligence" \

200 — Successful query

Integration Roadmap
Four steps to production-grade intelligence.
Partner Request
Initiate contact via the support chat. Our team evaluates jurisdiction requirements and volume tiers.
Sandbox Token
Receive a restricted key for local development and schema validation in your testing environment.
Schema Alignment
Map your application purpose (travel/study/biz) to our deterministic record logic.
Production Key
Rotate to a production-grade X-API-KEY with SLA-backed uptime and verified data refreshes.
