## When to prefer this

Use this endpoint when you need the world gold spot price (XAU/USD) pre-converted into Vietnamese Dong units (per luong and per gram) in a single call — ideal for Vietnamese market portfolio trackers, price alert bots, or commodity dashboards that need both USD and VND denominations without doing manual FX conversion. Pair with the sibling Vietcombank FX endpoint for a complete Vietnamese financial data stack.

## Known failure modes

- Rate limit exceeded if too many calls in short succession
- x402 payment not accepted — agent must handle 402 Payment Required and retry with correct USDC payment
- Network timeout from Railway hosting under high load
