Spot, walls, gamma flip, expected move and positioning levels.

Greeks profile

Aggregate and expiration-level gamma, delta, vanna and charm.

Options chain

Calls and puts organized by strike with prices, volatility and Greeks.

Market news

Structured market headlines with timestamps and related symbols.

Straightforward integration

One key. Clear JSON. Predictable endpoints.

Use a Bearer API key from your server, read the versioned response, and monitor daily allowance through the account usage endpoint.

Simple access model

Pay once. Use your daily allowance for the period shown in your plan.

Choose the daily request capacity that fits your workflow. There is no automatic renewal, and unused daily requests do not accumulate.

Each plan clearly shows its access duration. The daily allowance resets at 00:00 UTC. After access expires, buy the same plan or choose another one.
