ibm-quantum
IBM Quantum is IBM's quantum computing program — the operator of the IBM Quantum Platform (quantum.cloud.ibm.com), the publisher of the open-source Qiskit SDK, and the provider of the Qiskit Runtime REST API for submitting Sampler and Estimator primitive jobs to 100+ qubit Heron-generation QPUs and managed simulators. The platform combines an Apache-2.0 software stack (Qiskit, qiskit-ibm-runtime, qiskit-ibm-catalog, Qiskit Aer, Qiskit Serverless, Qiskit Functions) with a tiered access model (Open / Pay-As-You-Go / Flex / Premium / On-Premises) and is the longest-running commercial quantum computing API surface in the industry.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles ibm-quantum the way a machine reads it — 73 machine-readable artifacts across 11 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — ibm-quantum scores 69.2/100 (strong), with a separate agent-readiness read of 55/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.
How we profile ibm-quantum
Each block below is one kind of artifact we hold for ibm-quantum. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 11
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

Premium / Flex-tier service for discovering and invoking abstracted Qiskit Functions — pre-packaged quantum-classical workflows (e.g. circuit cutting, error-mitigation pipelines...

Postman Collections 6
A runnable collection turns the contract into something a developer can execute in seconds. We profile them because the fastest way to trust an API is to make a real call against it.

Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.
Multi-step API workflows described with the Arazzo specification.
IBM Quantum Audit Workloads and Drill Into Job
List recent job-mode workloads from analytics, then pull the full job record and metrics for the most recent one.
ARAZZOIBM Quantum Backend Readiness Preflight
Verify a backend is online, then gather its calibration properties and pulse defaults for circuit transpilation.
ARAZZOIBM Quantum Cancel Running Job
Check a job's status and cancel it only if it is still queued or running.
ARAZZOIBM Quantum Job Results and Logs
Poll a job to completion, then retrieve both its result payload and its execution logs.
ARAZZOIBM Quantum List Jobs and Inspect
List recent jobs, then pull the full details and execution metrics for the most recent one.
ARAZZOIBM Quantum Negotiate Version and List Backends
Discover the live API version, then list accessible backends and check one backend's status using that version.
ARAZZOIBM Quantum Pause Session and Confirm
Read a session's state, toggle whether it accepts new jobs, and confirm the change.
ARAZZOIBM Quantum Select Backend and Submit Job
List accessible backends, inspect a chosen backend's configuration, and submit a job to it.
ARAZZOIBM Quantum Session Run and Close
Open a Qiskit Runtime session, run a job inside it, then close the session.

Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

RATE LIMITSFinOps 1
Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Semantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.
Example request and response payloads for these APIs.
Security Posture 3
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
