GET
List Markets
No authentication required — this is a public read endpoint. Do not send an X-API-Key header; it is neither required nor checked. Start here to discover which markets are available. Each entry tells you:
  • conditionId — pass this to List Series to see every individual option series for that market.
  • strikes — which strike prices (in basis points) are available.
  • expiries — which expiry dates are available (Unix timestamps).
  • optionTypes — whether calls, puts, or both are listed.

Typical workflow

  1. Call GET /v1/markets to see what’s tradeable.
  2. Pick a market and call GET /v1/series?conditionId=0x... to browse its series.
  3. Open a quote request with the desired series parameters.
