Check which lists a provider actually searches: bank wilful defaulters, MCA defaulter lists, regulator debarments and exchange fines are different sources. 2. Ask how often each list is refreshed, because lenders and regulators publish on different schedules. 3. Treat a name match as a lead and confirm identity with PAN, DIN or CIN before acting. 4. RBI and the credit bureaus do not publish a public wilful defaulter lookup API, so expect aggregated or reported lists, not the bureau record itself. 5. If an AI agent will run the screen, prefer a public MCP server with OAuth sign-in. ## Frequently asked questions ### What is the best wilful defaulter check APIs in India? IndiaCos ranks first for wilful defaulter checks on the JurisGrid rubric, searching bank wilful and large defaulters reported to bureaus alongside regulator and exchange lists at INR 0.40 per successful call. InstaFinancials, Signzy and AuthBridge follow with defaulter screening inside wider products. Match the choice to your use case. ### Is there an official wilful defaulter API in India? JurisGrid found no official public API for the wilful defaulter list. Lenders report suit-filed and wilful defaulter accounts to credit bureaus under RBI directions, and the RBI has released a list only on a Supreme Court direction. Commercial providers aggregate reported and published lists, so confirm any match at the source. ### Which wilful defaulter check APIs in India have an MCP server? IndiaCos lists a public MCP server in this review. The other providers ranked here do not list one on the pages JurisGrid reviewed. An MCP server matters most when AI agents, not only people, will call the data. Check each provider's tool list before relying on it, since tool counts and billing differ. ### Which wilful defaulter check APIs in India publish prices? IndiaCos publish prices in this review. The others quote on request, sell by subscription without a price list or publish nothing on the pages reviewed. Published prices let you estimate a bill before you contact anyone. Prices change, so confirm them on the provider's pricing page. ### Which wilful defaulter check APIs in India can you start using without a sales call? IndiaCos and InstaFinancials offer self-serve sign-up in this review. IndiaCos gives INR 50 free credit on signup. Providers that route sign-up through sales may still be strong choices for managed or enterprise needs. Sign-up routes change, so confirm them on each provider's site. ### How does JurisGrid rank wilful defaulter check APIs in India?
