Overview

QSIM: exact statevector simulation of quantum circuits up to 12 qubits (H,X,Y,Z,S,T,RX,RY,RZ,CNOT,CZ). Classical compute — mathematically exact amplitudes. POST {qubits, gates, shots}

Endpoint

Method	Endpoint	Price	Description
POST	/v1/marketplace/api/qsim	$0.115	Invoke Qsim (Data Tools) and return the upstream response.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/qsim \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/qsim \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
