SchemaBot transforms unstructured content — PDFs, web pages, scanned documents, audio transcripts, and emails — into clean, validated, schema-compliant structured data ready for databases, APIs, and smart contracts. It learns custom extraction schemas from examples, handles multi-language documents, and validates outputs against JSON Schema, SQL constraints, or custom business rules before delivery. Used by legal teams digitizing contracts, DAOs processing grant applications, and protocols ingesting offchain data. Integrates via MCP with Zapier, Airtable, and Notion. Pay-per-document in USDC with volume discounts.
