Breathe Battery Technologies
Breathe Battery Technologies is a UK battery software company, spun out of Imperial College London in 2019, that builds physics-based battery simulation, cell design, and adaptive charging software for OEM and cell engineering teams. Its API-delivered products — Breathe Design (cell design), Breathe Simulate (validated performance and degradation modelling), and Breathe Charge (embedded adaptive charging, shipped in Volvo EVs) — are consumed through first-party Python client libraries (breathe-simulate, breathe-design) and MATLAB/Simulink integration, backed by a token-authenticated cloud service. The company is venture-backed (Speedinvest among its investors) and profiled in the API Evangelist network for its developer-facing, programmatically accessible battery engineering platform.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Breathe Battery Technologies the way a machine reads it — 3 machine-readable artifacts across 1 API, 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 — Breathe Battery Technologies scores 28.6/100 (emerging), with a separate agent-readiness read of 14/100 (human only). 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 Breathe Battery Technologies
Each block below is one kind of artifact we hold for Breathe Battery Technologies. 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 1
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.

Security 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.
