Works with 40+ Indian financial institutions
How it works
Send Document
→Base64-encoded PDF, PNG, or JPEG. Any Indian bank format.
AI Extraction
→Claude Vision classifies and extracts every field. 40+ bank layouts handled.
Structured JSON
Typed data with account details, transactions, validation, confidence.
Built for Bharat.
For agent builders who ship.
Purpose-built to extract structured data from Indian financial documents — bank statements, ITR forms, CIBIL reports, and more. Every bank format, every edge case, every lakh and crore.
Every Indian financial document
Bank statements, CAS reports, salary slips, ITR forms, CIBIL reports, GST invoices. HDFC, SBI, ICICI, Axis, CAMS, KFintech — 40+ formats.
Validated, not just extracted
Balance reconciliation, sum checks, sequential consistency. Every response tells you exactly what's wrong.
Drop into any agent
Ships with tool definitions for Claude, LangChain, and Vercel AI SDK. One import and your agent reads financial documents.
Nothing stored. Ever.
Documents processed in memory and discarded. No storage. No logs. No retention. Your users' data never leaves the pipeline.
Trust signals on every field
Confidence scores let your agent decide — act on high-confidence data, flag low-confidence for human review.
Three lines to
structured data.
No SDK required — just HTTP. But the SDK gives you types, auto-retry, and one-line agent integration.
bun add @lekha-dev/sdk
Zero dependencies. Native fetch.
Auto document detection
Pass type: "auto" — we classify it for you.
Full TypeScript types
Every document format, every field, fully typed.
| 1 | import { Lekha } from "@lekha-dev/sdk"; |
| 2 | import fs from "fs"; |
| 3 | |
| 4 | const lekha = new Lekha("lk_live_..."); |
| 5 | |

| 8 | type: "auto", |
| 9 | }); |
