Named backends.
Honest status.
Every quantum backend behind SynapseX, by name: free simulators that run in production today, and partner QPUs in gated early access. Each row says exactly what it is, what it costs, and whether you can press run.
Free simulators.
Running in production.
Every simulator below runs in production today and costs 0 credits, on every plan. Most experiments never need to leave this table.
Partner hardware.
Supported, gated.
Adapters for six partner QPUs are code-complete and supported. Execution is in early access: it opens after enablement and a paid reservation — we don't tag hardware live until you can press run.

Estimate. Reserve.
Settle.
1 credit is $0.01, simulators cost 0 credits, and paid hardware never bills blind. Every job is priced before it runs, credits are reserved at submit, and the ledger settles to what the run actually used — with a sealed record you can audit.
Estimate before any spend
POST /api/v1/runtime/estimate prices the job first. No credit moves until you have a number and say yes.
Reserve at submit
Submitting a paid job reserves the estimated credits up front — a run can never spend money you haven't set aside.
Settle to actual usage
When the job finishes, the reservation settles to what was actually used. Unused credits return to your balance.
Sealed evidence, every job
Each job ships a sealed evidence bundle — a Merkle SHA-256 record of what ran, where, and what it returned.
Four endpoints.
The whole surface.
The same catalog this page renders is one GET away. List backends, estimate the cost, submit the job, collect the artifacts — every response carries the job's sealed evidence bundle so the result can be checked by someone who wasn't in the room.

Thirteen simulators at 0 credits, in production right now. Escalate to partner hardware only when the evidence says so — and only after you approve the estimate.
