# FreightUtils — long-form index > FreightUtils — neutral freight reference + validation layer for AI agents. Source-backed dangerous-goods, customs, location and freight-calculation data an agent can call and cite, from primary sources (ADR 2025/UNECE, HS 2022/WCO, IATA-regulated airline prefixes, UN/LOCODE). Every response cites its source: authority, edition, licence where held, and a verification status an agent can read. Deterministic tools, not generated answers. Reference only — never filing, booking, or legal advice; results state when human review is required. Neutral by design: no freight to sell, no carrier to push. Built by a UK ADR-certified freight transport planner. Generated 2026-08-10 from on-page metadata of each route. The structured sitemap, OpenAPI 3.1 spec, and a shorter sectioned link list (llms.txt) are all linked below. Reference datasets (ADR UN numbers, HS codes, airlines, UN/LOCODE, etc.) are listed at the index level only — individual rows are queryable via the REST API at https://www.freightutils.com/api-docs and the MCP server at https://www.freightutils.com/api/mcp.
