Best for: StructOCR
StructOCR is a document-parsing API aimed at three specific workflows — KYC and identity verification, accounts payable, and global logistics — rather than at general-purpose OCR. It converts passports, national IDs, driver's licences, vehicle registrations, invoices, receipts, VINs, container numbers, hull identification numbers, licence plates and ATM cassette labels into structured JSON with named fields, using proprietary models per document type instead of one generic text-extraction pass. The identity output is the clearest illustration: a driver's licence request returns document number, surname, given names, address, vehicle class, sex, date of birth and the issue and expiry dates as separate typed fields, not as a block of recognised text a caller then has to parse. Coverage spans 193 countries and territories and over 100 languages, with a published 99.9% data-extraction accuracy figure and sub-four-second average response times for real-time verification. The commercial model is pure pay-as-you-go with no subscription at any tier, priced in credits at a base rate of one credit per cent: standard documents such as VIN, container, HIN, receipt and licence plate cost one credit, identity documents two, and invoices three, reflecting genuine differences in extraction difficulty. Credits never expire and larger top-ups carry bonus credits up to 71%, which brings the effective per-scan cost below a cent at volume. New accounts get 200 free credits without a card.
Ideal use cases:
- •Teams or individuals who need purpose-built models per document type rather than generic ocr
- •Teams or individuals who need typed json output with named fields, not raw recognised text
- •Teams or individuals who need coverage across 193+ countries and territories and 100+ languages
