Multiverse Computing
Multiverse Computing, S.L. is a Donostia-San Sebastian (Spain) quantum- and AI-software company whose commercial developer surface is the CompactifAI API — an OpenAI-compatible LLM inference service serving tensor-network-compressed versions of frontier open models (Hypernova 60B, Carina 60B, Mistral Small 3.1 Slim, Whisper Large V3 Turbo Slim) alongside uncompressed third-party models (GPT-OSS 120B, GLM 5.1/5.2, Quasar 438B, Qwen 3.6 27B, Nemotron 3 Nano Omni). The API is published at api.compactif.ai with regional EU and US endpoints, documented at docs.compactif.ai, billed pay-as-you-go per million tokens, and also sold through the AWS Marketplace. The company additionally sells Singularity, a quantum and quantum-inspired optimization product for finance, energy and manufacturing, which has no public developer documentation.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Multiverse Computing the way a machine reads it — 10 machine-readable artifacts across 2 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 — Multiverse Computing scores 50.5/100 (developing), with a separate agent-readiness read of 26/100 (agent aware). 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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Multiverse Computing
Each block below is one kind of artifact we hold for Multiverse Computing. 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 6
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.
Multiverse Computing Audio API
The audio API from Multiverse Computing — 1 operation(s) for audio.
Multiverse Computing Batches API
The batches API from Multiverse Computing — 3 operation(s) for batches.
Multiverse Computing Completions API
The completions API from Multiverse Computing — 2 operation(s) for completions.
Multiverse Computing Files API
The files API from Multiverse Computing — 2 operation(s) for files.
Multiverse Computing Model info API
The Model info API from Multiverse Computing — 2 operation(s) for model info.
Multiverse Computing Responses API
The responses API from Multiverse Computing — 2 operation(s) for responses.
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 things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
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.
Multiverse Computing Rate Limits
RATE LIMITSSecurity Posture 2
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.

This is an independent, third-party profile of Multiverse Computing, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
