Calculator API and Static JSON Data

Static JSON files for RupeeCalc calculators, tax-slab assumptions, and official-source registry for transparent Indian finance calculations.

Static calculator data endpoints

RupeeCalc provides static JSON files for calculators, source registry, and tax-slab assumptions. These are designed for transparency, audits, and citations — not as legal, tax, or investment advice.

/api/calculators.jsonList of available calculators, formulas, source notes, and update dates./api/tax-slabs-ay-2026-27.jsonRupeeCalc’s current AY 2026-27 tax-slab assumption file for calculator transparency./api/source-registry.jsonOfficial and high-trust source registry used by RupeeCalc pages.

Example usage

fetch('https://rupeecalc.in/api/calculators.json')
  .then(r => r.json())
  .then(data => console.log(data.calculators));

The files are static. Always check the last_verified field before citing a financial rule.

Source, accuracy and review note

Static calculator data philosophy

RupeeCalc is primarily a browser-based calculator website, not a financial-data API provider. The static JSON files are provided for transparency, internal tooling and future calculator consistency. They should not be treated as guaranteed real-time data feeds.

Calculator registry: helps identify available tools and page purpose.

Tax slab data: should be reviewed whenever official rules change.

Source registry: helps keep source and methodology pages aligned.

Repeat-use roadmap: supports bookmarkable workflows and content planning.

Developers or publishers who want to reference RupeeCalc should link to calculator pages rather than scraping outputs. Financial decisions should always be verified against official and professional sources.

Why this page is indexable

This page is part of RupeeCalc’s trust and discovery layer. It helps users, publishers, users and publishers understand how the site should be used responsibly. Calculator websites are easy to copy at a surface level; the harder part is maintaining clear purpose, safe claims, source discipline and repeat-use workflows.

For that reason, RupeeCalc does not rely only on calculator outputs. It also provides explanations, update notes, policies and practical navigation pages so visitors can decide which tool is relevant and what assumptions need verification.

Developer and publisher caution

Static data files may help explain calculator assumptions, but they are not service-level APIs. A publisher should not build a compliance or financial product that depends on these files remaining unchanged. If an external site references RupeeCalc, the safest practice is to link to the relevant human-readable page where the assumptions and disclaimers are visible.

This approach also supports search and automated tools because it keeps context attached to calculations. Numbers without explanation are easy to misuse. RupeeCalc’s goal is to keep formula, assumption, caveat and action together.
