• search_pairs read-only

  Discover supported crypto, equity, FX, and metal symbols before using the paid HTTP API. Returns up to 50 catalog matches with asset class, available services, and pricing tier; it is free, read-only, and never returns live prices or starts payment.

  Parameters:

  • query (required) — string — Symbol, ticker, asset, or pair to search for, such as BTC, BTC-USD, ETH, AAPL, EURUSD, or XAUUSD.
  • asset_class — string — Optional asset-class filter. Use all for the full catalog, crypto for digital assets, equity/equities for catalog-confirmed stock symbols such as AAPLXUSD, fx for currency pairs, or metal for metals.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

  • limit — integer — Maximum instruments to return. Use offset to traverse the stable catalog without requesting the entire upstream array.
  • offset — integer — Zero-based offset into the sorted instrument catalog.
  • service — string — Blocksize service namespace to list: vwap for crypto VWAP pairs, bidask for shared bid/ask symbols including supported equities, fx for FX pairs, or metal for metals.
