Ranks nearby stations by a price + distance cost model and returns a best-deal recommendation with an explicit freshness verdict (🟢 live GNCV vs 🟡 historical gasoline/diesel) and honest coordinate resolution (open GNCV coords are municipal centroids, so distances are shown approximate and intra-municipality ranking is by price). Dependency-free bun core. USE WHEN the user asks where to buy the cheapest gas/fuel/GNCV near a Colombian location, wants to compare station prices, or wants to build/extend fuel-price ingestion. NOT FOR non-Colombian markets or real-time gasoline/diesel (open data is GNCV-only live; gasoline/diesel is frozen ≈2022 — the SICOM birest endpoint is empty and Google Places needs a licensed key).

# gasgo — best gas deal near me (Colombia)
Engine that answers **"where should I go right now for the best gas deal?"** using
live per-station Colombian fuel-price open data.
## Invoke
```bash
bun run src/cli.ts where --city bogota --product gncv --radius 20 --top 5
bun run src/cli.ts where --lat 4.65 --lng -74.08 --product gncv
bun run src/cli.ts where --city medellin --product corriente --municipality medellin --json
```
Programmatic:
```ts
import { bestDeal } from "./src/engine.ts";
const res = await bestDeal({ at: { lat: 4.65, lng: -74.08 }, product: "GNCV" });
```
- **Products:** `gncv` (live) · `corriente` · `extra` · `diesel` · `biodiesel` (historical)
- **Cities:** bogota · medellin · cali · barranquilla · cucuta · bucaramanga · pereira
- Set `SODA_APP_TOKEN` to lift the anonymous Socrata rate limit.
See `README.md` for the data-source table, ranking model, gotchas, and roadmap.
## Tests
```bash
bun test # geo, date-gotcha, ranking, product-classification, geo-resolution honesty (32/32)
```
