Supported and Unsupported Scope

Supported

Image formats

Size limits

Receipt types

• Checkout screenshots from Blinkit, Swiggy, and Zepto
• INR-denominated receipts with payment labels in English or Devanagari script

Currency

INR only. The recognition pipeline is tuned for Indian rupee currency markers (₹, Rs., INR). Passing currency="USD" or any other non-INR value raises ConfigurationError immediately.

INR is the only production-scope currency. Other currencies are not recognized in the current runtime baseline.

Output

The package produces a payable-total suggestion only:

• The amount the customer owes (from "to pay", "amount payable", etc.)
• The currency code ("INR")
• An evidence grade and corroborating metadata

Not supported

The following are explicitly outside the current scope. Submitting an image that falls into these categories will not raise an error — it will return evidence_grade="none" or an unreliable "review" result.

File formats not supported

• PDF — single-page or multi-page
• HEIC / HEIF
• TIFF
• Animated GIF or WebP

Receipt types not supported

• Handwritten receipts
• Scanned physical paper receipts (low-quality scans may fail)
• Multi-page receipts
• Non-Blinkit/Swiggy/Zepto checkout flows (may work incidentally but are not tested)

Data extraction not supported

• Line-item extraction — individual products, quantities, prices
• Merchant name extraction — store name, branch, address
• Date / time extraction — transaction timestamp
• GST / tax breakdown — tax components are visible but not returned as structured fields

Infrastructure not supported

• Receipt storage — the package produces an in-process result only; no database writes
• Authentication / authorization — caller responsibility
• HTTP server or REST API — the package is a library, not a service
• Currencies other than INR — USD, EUR, GBP, etc. are not production-scope

Platform not supported as conformance target

• ARM (Apple Silicon, Raspberry Pi, etc.) — runs in development mode; not conformance-tested
• Windows — not tested
• Tesseract versions other than 5.3.4 — the package runs but sets conformant=false

Scope and the v1 gate

The v1 accuracy gate covers only Blinkit, Swiggy, and Zepto checkout screenshots in INR, on the retained Ubuntu 24.04 / amd64 / tesseract 5.3.4 runtime. Meeting the gate on that corpus does not imply the package will perform identically on other receipt types, apps, or currencies.

See Release gate for the full checklist.
