GET https://2s.io/api/trade/locode · 1 observation
Look up or search UN/LOCODE — the United Nations Code for Trade and Transport Locations (~116k locations, all countries). Pass `locode` for an exact code (e.g. USNYC or 'US NYC'). Or pass `query` to search location names, optionally filtered by `country` (ISO 3166 alpha-2) and `function` (port, rail, road, airport, postal, multimodal, fixed, border). Each result: locode, name, country, subdivision, transport functions, entry status, IATA code where it differs, and coordinates. UN/LOCODE is the s

Look up or search the US Harmonized Tariff Schedule (HTS / HS codes). Pass `code` for an exact HTS number (dots optional) — returns that line plus its 10-digit statistical suffixes with duty rates. Or pass `query` for free-text search (e.g. 'electric toothbrush', 'roasted coffee') → ranked candidate HS codes by hierarchical heading. Each result: htsno, chapter, description, full heading path, units, and duty rates (general/MFN, special/FTA, column-2). ~29.6k lines, public-domain USITC data. The

Returns {valid, type, gtin14 (canonical 14-digit form, left-padded), checkDigit, reason}. Normalizes every product identifier to one GTIN-14 key so a product-master/ETL pipeline can dedupe and validate SKUs in one deterministic call instead of doing checksum math in an LLM.
