Riverlane

Riverlane is a Cambridge (UK) quantum computing company building the quantum error correction (QEC) stack. Its two product lines are Deltaflow — a real-time QEC system covering qubit data readout, decoding, logical operations and orchestration, running error correction on up to 250 physical qubits with the proprietary Local Clustering Decoder — and Deltakit, an Apache-2.0 open-source Python SDK for designing, generating, simulating, decoding and analysing QEC experiments. The public developer surface is the Deltakit cloud service at https://deltakit.riverlane.com/proxy, a bearer-token API with two coexisting versions: a GraphQL endpoint (/api/graphql, API v1) and an asynchronous task REST API (/api/v2/tasks/add|get|kill, API v2). Both front Riverlane's proprietary decoders (Ambiguity Clustering, Local Clustering, Collision Clustering), leakage-aware decoding and simulation, iSWAP native-gate circuit generation, and stability-experiment generation. Riverlane publishes no OpenAPI or AsyncAPI document; the machine-readable contract is the open-source client library at github.com/Deltakit/deltakit, which is where every endpoint recorded in this profile was read from.

Riverlane publishes 1 API on the APIs.io network. Tagged areas include Quantum Computing, Quantum Error Correction, Decoders, Scientific Computing, and Python SDK.

Riverlane’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, changelog, and 24 more developer resources.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 90 points between them, because the conditional facet above carries the other 10. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 90% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/riverlane: open an issue to ask a question, or submit a pull request to add artifacts.
