Technical details
Endpoint
GEThttps://tick.hugen.tokyo/tick/latestWhen to prefer
Use this endpoint when you need tightly aggregated institutional FX prices with spread quality metadata — particularly useful for AI trading signals, portfolio mark-to-market valuation, spread arbitrage detection, or any application where knowing source freshness and spread quality relative to single-source feeds matters. Prefer over single-source FX APIs when spread tightness and multi-source confidence are important.
Side effects
- Invalid or unsupported symbol returns error — only 14 pairs supported (EURUSD, USDJPY, GBPUSD, AUDUSD, AUDNZD, XAUUSD, etc.)
- Payment failure (USDC not provided or insufficient) results in 402 Payment Required
- All sources stale may result in degraded quality_state or no fresh quotes
- Network timeout if liquidity providers are unreachable
- Crossed market (is_crossed: true) indicates unusual spread condition
