Choosing a receipt OCR API in 2026 means wading through marketing claims, opaque pricing pages, and demo videos that never show the hard cases — faded thermal receipts, crumpled handwritten notes, multilingual grocery bills.

We ran the same test dataset through four leading APIs and documented what actually happened.

The contenders

API	Model	Founded	Free tier
ReceiptConverter	GPT-4o Vision	2024	10/mo
Veryfi	Proprietary OCR	2017	100/mo (trial)
Mindee	Proprietary + OWN	2018	250/mo
Taggun	Google Vision	2016	100/mo

Accuracy on real receipts

We tested 200 receipts across five categories: restaurant, grocery, gas station, hotel, and e-commerce. Each receipt was graded on vendor extraction, total extraction, line item accuracy, and date parsing.

Restaurant receipts

The hardest category — handwritten specials, messy totals, variable tip lines. ReceiptConverter and Mindee both scored above 94% on total extraction. Taggun dropped to ~82% on non-standard layouts.

Grocery receipts

Long receipts with dense line items. All four APIs performed well on total extraction. Line item accuracy varied significantly: ReceiptConverter leveraged GPT-4o's contextual understanding to handle items like "ORGNC CRNBRY JCE 32OZ" correctly — older OCR models often truncated or mislabeled these.

Faded thermal receipts

This is where model architecture matters. Traditional OCR (Tesseract, Google Vision-based) fails on low-contrast text. GPT-4o Vision's image understanding significantly outperforms traditional pipelines on degraded receipts.

Pricing comparison

API	Free	Pay-as-you-go	$9/mo	$19/mo
ReceiptConverter	10/mo	—	100/mo	500/mo
Veryfi	Trial only	$0.08/doc	~$50/mo	~$150/mo
Mindee	250/mo	$0.10/page	—	—
Taggun	100/mo	$0.05/doc	$49/mo	—

ReceiptConverter is the most affordable option for low-to-medium volume. For high-volume enterprise use cases (10,000+ receipts/month), contact each vendor for custom pricing.

Response schema

A good API returns more than just the total. Here's what each API returns by default:

Field	ReceiptConverter	Veryfi	Mindee	Taggun
Vendor name	✅	✅	✅	✅
Total	✅	✅	✅	✅
Subtotal	✅	✅	✅	✅
Line items	✅	✅	✅	❌
Tax breakdown	✅	✅	✅	Partial
Tip	✅	✅	❌	❌
Payment method	✅	✅	❌	❌
Category	✅	✅	❌	❌
Currency	✅	✅	✅	✅

Developer experience

ReceiptConverter ships an OpenAPI 3.0 spec, an llms.txt for AI agents, an AGENTS.md file, and full documentation at receiptconverter.com/docs. The API accepts both multipart/form-data file uploads and JSON { url: "..." } requests. No SDK required.

Veryfi has the most mature SDK ecosystem (Python, Node, iOS, Android) but at significantly higher price points.

Mindee's strength is document AI beyond receipts — passports, invoices, tax forms. If you need a multi-document pipeline, it's worth considering.

Taggun is the simplest API in the group but returns less structured data.

The verdict

For startups and individual developers: ReceiptConverter offers the best accuracy-to-price ratio with a generous free tier and simple HTTP API.

For enterprise / high volume: Veryfi and Mindee offer better SLAs and compliance features.

For multi-document pipelines: Mindee if you need passports, IDs, and invoices alongside receipts.
