CORE CAPABILITIES

Own the entire LAS journey

Every step of Loan Against Securities, exposed as a single, composable API suite.

Orchestration

Multi-lender orchestration

Route every application across 12+ RBI-regulated lenders in a single API call. Best rate wins, automatically.

Compliance

KYC & e-pledge

Aadhaar, PAN and bank verification, plus CDSL/NSDL lien creation, all handled inside the same request lifecycle.

Lifecycle

Disbursal & repayment

T+0 disbursal to customer bank accounts, with full repayment, foreclosure and part-payment handling built in.

Ownership

Own UI, own UX, own the brand

Lark OS is headless by design. Build your own interface, top to bottom, on top of our rails.

Economics

1/5th the cost of going direct

Volume-priced orchestration means integrating through Lark OS costs a fraction of going lender-by-lender.

Support

Dedicated solutions engineer

Every Lark OS partner gets a named engineer for integration support, custom SLAs, and data residency needs.

BUILT FOR ENGINEERING TEAMS

An API surface your team will actually enjoy

REST + webhooks, production-grade reliability, built on the same rails that move crore-scale wealth every day.

Global edge + API gateway

CloudFront + Cloudflare anycast with India-region pinning, rate-limits, mTLS and zero-downtime blue-green deploys.

Event backbone

At-least-once delivery, signed payloads, fully replayable webhooks for every loan lifecycle event.

Security & compliance

OAuth2, PATs and fine-grained RBAC, with mTLS, IP allow-listing and field-level encryption throughout.

Observability by default

Logs, metrics and traces with correlation IDs on every request, so nothing is a black box.
