Finding the cheapest fuel stations in Colombia requires analyzing both price and detour distance. A custom ranking engine calculates the effective cost by factoring in the fuel price per unit and the round-trip detour distance to ensure savings aren't lost to travel.

Querying live GNCV prices across major Colombian cities is possible using Socrata API integration with the government's open data portal. The system retrieves live price data and normalizes it for GNCV, gasoline, and diesel to provide accurate fuel-specific rankings.

Geographic coordinate processing for ranking fuel stations works by calculating the round-trip detour distance from your location to each station. This distance is combined with the fuel price per unit to model the effective cost of a stop, ensuring the ranking reflects true savings.

Bun is required to run this fuel price analysis skill. The environment uses Bun as its runtime dependency to execute scripts that integrate with the Socrata API, process geographic coordinates, and normalize fuel-specific price data for the ranking engine.

The best way to calculate detour costs when comparing gasoline and diesel prices is to use a ranking model that combines price normalization with geographic distance. This approach evaluates the effective cost of a fuel stop by factoring both the price per unit and round-trip travel.

A cheaper fuel price can result in a higher effective cost when the round-trip detour distance to the station outweighs the per-unit savings. The ranking engine models this by combining detour cost and fuel price, showing that distant stations may not actually save money.
