Solvers Resources¶

solver resources represent resources that run a problem.

SAPI Endpoints¶

The following table provides an overview of the SAPI URLs that map to solver resources.

Table 51 SAPI URLs¶
URL	Method	Reference
/solvers/remote/	GET	List Solvers
/solvers/remote/<solver_id>/	GET	Get Solver Configuration

Solver Properties¶

Table 52 Solver Resource Properties¶
Property	Description
description	Description of the solver.
property	Solver properties such as supported problem types, active qubits, active couplers, total number of qubits, and so on.
id	Unique ID of the solver.

For details on solver types, solver properties, and the problem-solving parameters that are supported by the different solver types, see the D-Wave Solver Properties and Parameters: Reference Guide.

List Solvers¶

Request¶

Retrieve the list of supported remote solvers by sending an HTTP GET request to $SAPI_HOME/solvers/.

Note

The solvers that are available vary by region.

This example uses curl to retrieve the list of remote solvers:

curl -H "X-Auth-Token: $SAPI_TOKEN" $SAPI_HOME/solvers/remote

Response¶

The system responds with 200 OK and returns list of solvers formatted as a JSON list.

Example of the output:

[
    {
        "properties": {
            "supported_problem_types": ["qubo", "ising"],
            "qubits": [ ... ],
            "couplers": [ ... ],
            "num_qubits": 512
        }
        "id": "Solver 1",
        "description": "Solver #1"
    },
    {
        "properties": {
            "supported_problem_types": ["ising"],
            "qubits": [ ... ],
            "couplers": [ ... ],
            "num_qubits": 512
        }
        "id": "Solver 2",
        "description": "Solver #2"
    }
]

Get Solver Configuration¶

Request¶

Retrieve the configuration of a solver by sending an HTTP GET request to $SAPI_HOME/solvers/. This example uses curl to retrieve the configuration of a remote solver:

curl -H "X-Auth-Token: $SAPI_TOKEN" $SAPI_HOME/solvers/remote/solver1

Response¶

The system returns solver configuration formatted as a JSON object.

Example of the output:

{
    "properties": {
        "supported_problem_types": ["qubo", "ising"],
        "qubits": [ ... ],
        "couplers": [ ... ],
        "num_qubits": 512
    }
    "id": "solver1",
    "description": "solver1"
}

The properties attribute holds the solver properties such as number of active qubits and couplers.

Response codes are as follows:

Table 53 Response Codes for `Get Solver Configuration`¶
Response Code	Meaning
`200`	Success
`404`	Solver with specified `solver_id` does not exist.
`429`	Number of API requests exceeds the permitted limit.
