CQ Catalyst-Q SDK

Exact Quantum and Optimization Execution for Production Teams

Submit Standard Inputs. Get Exact Results.

Catalyst-Q is a breakthrough simulator API and Python SDK for QASM circuits, SDK circuit objects, and optimization model payloads. Build with the inputs your team already uses, then validate outputs with reproducible benchmark artifacts.

Why price this way

Buyers understand qubits, circuit runs, solver runs, and compute limits. We avoid pricing language around internal memory dimensions because it is not how users evaluate value.

  • Free tier is generous enough for notebooks, demos, and integration work.
  • Production workflows require explicit permission.
  • Hosted compute, support, and deployment rights carry the price.
  • Overages can be added later without changing the SDK surface.
  • Private Deployments: Private, offline, and local workflows require custom licensing.

Upgrade trigger

Free users see: Free tier exceeded. Upgrade or wait until next month. The API returns the upgrade URL, checkout endpoint, reset time, and agent-readable billing manifest with the blocked usage response.

Machine-readable billing: /.well-known/catalyst-q/billing.json. Checkout starts at /billing/create-checkout-session and paid keys are returned once from /billing/checkout-session.
