## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability straits-live-bunker-price-api-fujairah-live-tracker-4b61c014
```

Example prompt: What's the current bunker fuel price at Fujairah right now — I need VLSFO, MGO, and IFO380 per tonne in USD, and how does Fujairah VLSFO compare to Rotterdam and Singapore?

## When to prefer this

Choose this endpoint when you need real-time marine bunker fuel prices specifically at Fujairah (the dominant bunkering hub for vessels transiting the Persian Gulf / Strait of Hormuz), including cross-hub spread data vs Rotterdam and Singapore. It is updated every 5 minutes and is purpose-built for the current Strait of Hormuz crisis context. Prefer it over generic commodity APIs when you need maritime-grade granularity (VLSFO/MGO/IFO380 split) and freshness guarantees with a stale flag.

## Known failure modes

- Stale data flag set to true if upstream AIS or price feed has not refreshed within expected window
- Payment failure or 402 response if x402 USDC micropayment is not completed
- Empty or null port entries if Fujairah price data is temporarily unavailable
- Schema mismatch if caller expects additional ports beyond Fujairah in the current response

## How this service works

Is the Strait of Hormuz open? Effectively no, it is closed to commercial shipping as of 13 July 2026. 34 ships transited vs ~88/day normal. Brent $81.10. Updated every 5 minutes.

## Output

A JSON object containing: timestamp (asOf), a ports array with per-port bunker prices in USD per tonne (VLSFO, MGO, IFO380) for Fujairah, a stale boolean indicating data freshness, and a spreads object showing Fujairah VLSFO differential vs Rotterdam and Singapore in USD per tonne.
