Refractr is a document extraction API that converts invoices, emails, and PDFs into validated JSON using a user-supplied schema. It processes documents in approximately 500 milliseconds per document and benchmarks competitively against models such as Gemini, DeepSeek, and GPT on field-level accuracy. Developers receive 100 free extractions per day, making it accessible for prototyping and low-volume production use. The service is purpose-built for structured data extraction workflows requiring schema-conformant output.
