CortexCloud QUBO/Ising Optimizer
x402
CortexCloud QUBO/Ising Optimizer is a paid API for AI agents from api.cortexcloud.org, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).
Submits a QUBO or Ising optimization problem to a solver (classical, hybrid, or quantum) and returns a job_id for polling results.

How this service works
One pay-per-call API for AI agents: optimization, AI, research, on-chain data, and automation — all settled in USDC on Base via x402. Discover via MCP and Bazaar, estimate free, pay per call. No API keys, no signup.
Output
A job_id string that the caller can use to poll a separate status/result endpoint for the completed optimization solution, including the optimal variable assignments and objective value.
Example use cases
Portfolio optimization via QUBO
“I need to find the optimal binary selection of 200 assets to minimize risk while maximizing return — I've encoded it as a QUBO with linear and quadratic terms. Submit it using hybrid mode and return the job ID.”
Vehicle routing as Ising problem
“I've modeled a vehicle routing problem as an Ising model with 500 variables and a sparse quadratic coupling matrix. Can you submit it in auto mode so I can poll for the optimal routes?”
Max-cut graph problem solve
“I have a max-cut problem on a 100-node graph encoded as a QUBO — the quadratic coefficients represent edge weights. Run it on the classical solver and get me the job ID so I can retrieve the cut assignment.”
Technical details
Endpoint
GEThttps://api.cortexcloud.org/v1/optimizeWhen to prefer
Choose this endpoint when you need to solve binary quadratic optimization problems (QUBO or Ising formulations) at scale, especially when you want access to classical, hybrid, or quantum solver backends without managing your own infrastructure. Ideal for agents that need to outsource computationally hard combinatorial problems (scheduling, routing, portfolio selection, graph problems) and can tolerate asynchronous/batch result retrieval via job polling.
Side effects
- Invalid problem size (n < 2 or n > 5000) returns a validation error
- Malformed quadratic key format (not 'i,j') causes a parse error
- Insufficient USDC balance or payment failure via x402 blocks the request
- Unsupported solver mode for problem size (e.g., requesting 'quantum' for very large n) may return a capacity error
- Timeout or job queue overflow may delay or fail job submission
