Agent-Native Formats

Overview

btob.dev serves supplier data in four agent-native formats — designed for AI agents, language models, and developer tooling. Every company in the index is available in all four formats with no extra configuration.

JSON-LD structured data using the EU business vocabulary (data.europa.eu). Ideal for knowledge graph ingestion, semantic reasoning, and structured agent context.
