## Which one should you choose?

### Choose AuthBridge if

- you want a managed background verification and due diligence service, not only data
- you want a negative due diligence check that names Bureau, CIBIL, Equifax, CRIF High Mark, Experian, nationalised banks and a wilful defaulter list
- you want employee and litigation checks from the same firm

Skip it if you need a public API reference, published prices or self-serve sign-up: these were not found for AuthBridge in this review.

### Choose Signzy if

- you want KYB with UBO checks, video KYB and AML screening inside an onboarding workflow
- you want a negative due diligence check that lists MCA defaulter directors, MCA defaulter entities, NSE defaulters and MCA disqualified directors
- you prefer a custom, sales-led contract over prepaid credits

Skip it if you need published prices, self-serve sign-up or a public MCP server: these were not found for Signzy in this review.

### Choose IndiaCos if

- you want company, LLP, GST, director, charge and court case records through one key and one per-call price
- you want AI agents to call company data through a public MCP server with OAuth and an agent sign-up flow
- you want a flat INR 0.40 per successful call, with errors and not-found calls free, and INR 50 free credit before you pay
- you need to go from a PAN to all linked GSTINs, or from a company name to its trade marks, patents and defaulter entries

Skip it if you need audited financial statements or a fixed annual fee with a contract: IndiaCos is a prepaid per-call service built from public records, and its company master date differs by company.
