Inkspan

Inkspan is a document API designed for developers and AI agents. It provides a single clean interface to generate, transform, and extract structured data from PDFs and other documents without requiring users to manage infrastructure or schedule sales calls.

The service supports PDF generation from HTML, templates, or Markdown, producing pixel-faithful output. Available endpoints include generate/html, generate/template, and generate/markdown. Transformation capabilities cover merging, splitting, compressing, watermarking, rasterizing, and filling forms through dedicated paths such as pdf/merge, pdf/split, pdf/compress, pdf/watermark, pdf/to-images, and pdf/fill-form. Extraction features pull text and tables into JSON, including confidence scores, via extract/text, extract/tables, and extract/data, with vision-language model support noted as forthcoming.

Every endpoint functions as an authenticated POST request. The platform supplies SDKs for multiple languages and includes quickstart examples in cURL, Python, and Node. It is delivered as a web API hosted at api.inkspan.dev, with a dashboard for managing API keys and reading documentation.

Inkspan operates on a free tier combined with usage-based pricing.
