IonQ
IonQ (NYSE IONQ) is a College Park, Maryland-based public trapped-ion quantum computing company. IonQ designs, manufactures, and operates trapped-ion quantum computers (Aria, Forte, Forte Enterprise, Tempo, Harmony) and delivers them through the IonQ Quantum Cloud REST API, on-premises Forte Enterprise systems, and partner clouds (AWS Braket, Microsoft Azure Quantum, Google Cloud). The platform supports submission of QIS and native-gate circuits, multi-circuit and Quantum Function jobs, reserved Sessions, error mitigation, and organization-level usage and cost reporting. IonQ's quantum networking, security (QKD), sensing, and space-infrastructure businesses extend the trapped-ion core into a broader quantum systems portfolio.
IonQ publishes 5 API contracts indexed on the APIs.io network, including Backends API, Characterizations API, Jobs API, and 2 more. Tagged areas include Quantum Computing, Trapped Ion, QPU, ARIA, and Forte.
The IonQ catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
IonQ’s developer surface includes authentication, developer portal, documentation, signup flow, getting-started guide, support, engineering blog, and 63 more developer resources.

Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted .
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons ; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
