Claix is a Madrid-based B2B document intelligence API that converts PDFs, Excel/CSV, Word and text documents and images into strictly typed JSON against customer-defined schemas, keeps extracted documents as queryable context for AI agents (single-document and knowledge-space Q&A with deterministic nulls), and exposes one 20-operation contract three ways: REST (OpenAPI 3.0.3), a hosted MCP server at /mcp, and a native A2A agent at /a2a with a published, conformant agent card. Pay-as-you-go in euros after 100 free calls, with a free BYOK mode; official Python SDK and n8n node.
