About the API

What this endpoint does.

Every address form in India stops on the pincode, and most user-typing of it is wrong. This endpoint validates a six-digit pincode against official India Post records and returns every office it covers — useful to auto-suggest cities and states as someone types a PIN.

Beyond validation it powers address auto-complete — pick the pincode first and the district and state fill themselves, which deletes whole classes of address-entry errors.

Who builds on this

Built for the teams shipping real products.

  1. 01

    E-commerce checkout

    Validate the PIN, then auto-fill district and state — fewer failed deliveries from bad addresses.

  2. 02

    Marketplaces & logistics

    Confirm a pincode is serviceable before quoting delivery timelines or COD availability.

  3. 03

    Forms & onboarding

    Replace a free-text city/state with a pincode-driven picker in any KYC flow.

Free tier

Ship on this API free, then pay only when your calls outgrow it.

  • A free monthly request allowance on your first key — enough to build and test.
  • The same key works across every endpoint, so you can switch APIs as you grow.
  • When the free requests end, upgrade to paid — your code and endpoints don’t change.

Every endpoint includes a free monthly request allowance — the size differs from API to API. When your free requests run out, you move to a paid plan with the same key. No card needed to start.
