About

Credit Cards of India is an open dataset and comparison site for every major credit card issued in India. It's built on top of a YAML dataset in the DrftingWood/credit_cards_india repository — every value on this site links back to the issuer page it came from.

How the data works

Fees, rewards and benefits are stored as effective-dated records: when an issuer revises an annual fee or reward rate, we close the old record with aneffective_until date and append a new one, so historical values are never lost. You can see these revisions on any card's page under History.

Every dated record carries a source.url and the date we retrieved it, so every number is traceable. The schema is a JSON Schema in schema/card.schema.json and the validator runs on every pull request.

Data quality

The dataset is in beta. Values were populated from widely-reported public figures and will have drifted for some cards since their retrieval dates. Always confirm with the issuer before applying. If you spot an error, please open an issue or a pull request on GitHub.

Out of scope (for now)

• Side-by-side card comparison.
• Favourites / bookmarks.
• Community reviews and ratings.
• Welcome bonuses and milestone vouchers in the calculator.

Contributing

See CONTRIBUTING.md in the repo. To add a card, run python scripts/new_card.py <issuer> <slug> "<name>", fill in the TODOs from the issuer's own page, and open a PR. CI runs the validator on every submission.
