get_trade_flow

Fetch bilateral trade flows between two countries for a commodity.

Data from UN Comtrade — 200+ countries, 6,000+ HS commodity codes, back to 1962.

Args:
reporter: Reporting country name or ISO numeric code (e.g., "Germany", "276").
partner: Partner country name or ISO numeric code (e.g., "China", "156").
Use "World" or "0" for global aggregates.
commodity_code: HS commodity code (e.g., "8471" for computers, "27" for fuels,
"TOTAL" for all commodities). Use search_commodities to find codes.
year_from: Start year (e.g., 2018). If omitted, returns most recent year.
year_to: End year (e.g., 2022). If omitted, same as year_from.
flow: Trade direction — "M" (imports), "X" (exports), "MX" (both, default).

Returns:
List of trade records with reporter, partner, commodity, flow, value (USD), and weight (kg).

`reporter`	`string`	required	Reporting country name or ISO numeric code (e.g., "Germany", "276").
`partner`	`string`	required	Partner country name or ISO numeric code (e.g., "China", "156"). Use "World" or "0" for global aggregates.
