Unstract vs Veryfi Invoices OCR API

Unstract is a document processing platform that extracts structured data from unstructured documents and automates document workflows. Prompt Studio uses natural-language instructions to build extraction projects that can be deployed as APIs or ETL pipelines. Agentic Prompt Studio uses multi-agent pipelines to define schemas, create extraction prompts, and validate results across documents. Unstract describes its document processing as document agnostic and says it works without prior training or templates. Human-in-the-loop workflows can route selected documents for review, approval, and validation. LLMChallenge uses two language models to challenge extracted responses; SinglePass and Summarized Extraction are described as ways to reduce token use. Integrations include Anthropic, OpenAI, and Vertex AI models, along with file systems and databases such as Azure Cloud Storage, PostgreSQL, and S3/Minio. Deployment options are managed cloud, on-premise enterprise, and open-source self-hosted editions. The cloud offering says data is encrypted in transit and at rest and is not used for training. The free Open Source plan is self-hosted and limited to one user. Starter costs $499 a month, billed monthly, with 5,000 pages monthly and a 0.10 USD per-page overage.

Veryfi Invoices OCR API extracts invoice information into structured JSON, including vendor details, line items, tax, and totals. It accepts documents such as PDFs and images, and the response includes OCR text for downstream applications. Veryfi says the API supports over 150 fields covering supplier, line-item, tax, and payment data. The product page describes checks for altered or duplicate invoices, including digital tampering analysis, PDF layer analysis, and duplicate detection. Developer resources include SDKs and code samples for Python, Node.js, PHP, C#, and Java, among other languages; n8n and Zapier are listed for workflow connections. Veryfi states that its platform is SOC 2 Type II certified and uses TLS 1.2 and 1.3, salted password hashing, and AES encryption at rest and in transit. It says it complies with GDPR, CCPA, and HIPAA, and will sign a BAA upon request. The API is described for accounts payable, bill pay, and three-way purchase-order matching. The free plan allows up to 100 documents monthly. Starter costs $500 a month, with a minimum commitment and a listed $0.16; each transaction covers a document up to 15 pages.
