Welcome to SignCare API
The SignCare External API is a unified B2B gateway for 60+ identity, financial, and eSign verification providers across India.
What is SignCare External API?
SignCare's External API is a B2B gateway that aggregates 60+ verification providers behind a single, consistent interface. Instead of integrating separately with each government ID database, biometric service, credit bureau, or signing provider, you integrate once with SignCare and route through us.
We handle the underlying providers, retries, failovers, tokens, and compliance. You focus on your product.
Two API products
SignCare Core API
Identity, KYC, eSign, eStamp, address, credit, and compliance APIs. 40+ verification endpoints.
WealthScape API
Account Aggregator (AA) framework, mutual fund connect, and financial insights APIs.

Ready to integrate?
Start with the Quickstart — you can have a working verification in under five minutes with curl. Then read up on authentication and rate limits before you go live.
Environments
We operate two public environments. Same API keys, different hostnames.
| Environment | Base URL | Use for |
|---|---|---|
| Stage | https://uat-ext.signcare.io | Integration, UAT, sandbox |
| Live | https://ext.signcare.io | Production traffic |
Your API key and App ID work in both environments. Switch by changing the hostname. See Environments for details.

Who is this for?
SignCare is built for B2B consumers — banks, NBFCs, fintechs, insurers, real-estate platforms, lending apps, HR-tech, and anyone doing customer onboarding or document signing at scale. It is not for end-user self-service — your users never see SignCare.
