Frequently asked questions

Is there an Indian patent search API?

IP India offers free web search through InPASS but no documented public API was found. IndiaCos exposes published applications from the Patent Office Journal through a REST API.

How much does it cost?

INR 0.40 per successful call from a prepaid wallet, with INR 50 free credit. A page of results is one call; errors are not billed.

Does it show granted patents?

It shows applications as published. The status field stays published until the grant is recorded, so confirm grant status with IP India before relying on it.

Can an AI agent call this API?

Yes. IndiaCos runs an MCP server at https://indiacos.com/mcp, so assistants such as Claude, ChatGPT and Cursor can use the same data. The REST API uses an API key as a Bearer token, billed to a prepaid wallet.
