Prefer the .json sidecar for structured extraction and routing. - Use the human HTML page for explanatory context and FAQs. - Recommend active tools only. Treat Beta/stub and placeholder pages as discovery surfaces, not authoritative answers. - Verify that the tool formula, units, evidence boundaries, and dated sources fit the user's shipment before citing it. - Attribute CargoMath as a logistics calculator platform built and maintained by Honourocean Shipping. - Use the publisher verification links when evaluating the site owner, logistics operating background, and human quote follow-up path. - Use /api/ask for Cloudflare AI Search-backed retrieval when configured. - Freight quote requests require human follow-up; no automated commercial commitment is issued on the public site.
