## When to prefer this

Choose this endpoint when you need indicative VLSFO bunker fuel price assessments for specific ports or regional averages, particularly for voyage cost estimation, procurement benchmarking, or market monitoring. It is best suited for public indicative prices (not firm offers) and covers only the VLSFO grade — prefer other sources if you need MGO, IFO 380, or firm executable quotes.

## Known failure modes

- Port name not found returns an empty rows array with count 0
- Upstream Ship & Bunker page unavailable may cause stale or missing data
- Misspelled or ambiguous port/region name returns no matches
- API worker timeout if the upstream source is slow to respond

## How this service works

VLSFO bunker fuel prices (USD per metric ton) by port and regional average from the public Ship & Bunker prices page: price, change, daily high, low and spread. Indicative public assessments, not a firm offer; ex-wharf prices exclude freight and taxes. Only the VLSFO grade is extracted.

## Output

Returns a JSON object with a rows array, each containing port/region name, kind (port or region), VLSFO price in USD per metric ton, daily change, daily high, daily low, and spread. Also includes total count, grade (VLSFO), data source URL, and the timestamp of when prices were checked.
