About this repository

This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.

Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema, apis.json, llms.txt and similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.

The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.

Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.

  • Something wrong? Open an issue on this repository, or email info@apievangelist.com.
  • Published something new? Ask for a re-score and we will re-run the rating.
  • Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.

Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.

On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.

Full detail: Where this data comes from

Rigetti Computing (Nasdaq, RGTI) is a Berkeley, California-based quantum computing company building superconducting quantum processors and the full-stack software needed to program and operate them. Founded in 2013 by Chad Rigetti, the company designs, manufactures, and operates multi-chip superconducting QPUs at its Fab-1 in Fremont, CA and offers cloud-based access through Quantum Cloud Services (QCS). Rigetti also sells the Novera QPU (9-qubit) for on-premises customers and provides Quantum Foundry Services for custom development. The current generation system Cepheus-1-108Q (107 qubits, deployed April 2026) is accessed via a hybrid REST + gRPC API surface, programmed using the open Quil instruction language, the pyQuil Python library, and the multi-language qcs-sdk (Rust core with Python bindings). Rigetti's hardware is also available indirectly through AWS Braket, Microsoft Azure Quantum, and as a Qiskit provider via qiskit-rigetti.

APIs

Rigetti QCS API

The Rigetti Quantum Cloud Services (QCS) HTTP API is the OpenAPI-specified REST surface for managing accounts, groups, users, billing, reservations, endpoints, engagements, and discovering quantum processor metadata including Instruction Set Architecture (ISA) and calibration. Authentication is OAuth2 (JWT bearer) issued via Okta. The API follows Google API Improvement Proposals (AIP) and is paired with a gRPC API for quantum program translation and controller execution against the QPU.

Properties

Rigetti QCS Translation Service (gRPC)

gRPC Translation service that compiles native Quil programs into encrypted Controller Jobs for execution on a Rigetti QPU. Operations include TranslateQuilToEncryptedControllerJob and GetQuantumProcessorQuilCalibrationProgram. Authenticated with the same JWT bearer token used by the QCS HTTP API and consumed via qcs-sdk-rust/qcs-sdk-python or the Rust qcs-api-client-grpc crate.

Properties

Rigetti QCS Controller Service (gRPC)

gRPC Controller service that executes encrypted Controller Jobs on a Rigetti QPU endpoint and returns measurement (readout) results. Operations include ExecuteControllerJob, BatchExecuteControllerJobs, GetControllerJobResults, CancelControllerJobs, and GetControllerJobStatus. Used through qcs-sdk-rust / qcs-sdk-python after obtaining a CreateEngagement token from the QCS HTTP API.
