The first call most integrators make. Returns every symbol the API supports with the categories of data currently live for each, the spot price, the count of active expiries, and the full set of endpoint paths that accept a symbol parameter. Use it to:
  • Discover which symbols are supported (BTCUSDT, ETHUSDT, SOLUSDT, HYPEUSDT)
  • Check at a glance whether a symbol has live cache data before hitting downstream endpoints
  • Build a dynamic UI that lists supported endpoints without hard-coding paths
Powered by a single Redis MGET round-trip - sub-millisecond when warm.
