DESKi
DESKi is a French medical-device software company founded in 2016 in Bordeaux by brothers Bertrand and Olivier Moal, trading publicly under its HeartFocus brand. Its flagship product, HeartFocus, is an FDA-cleared AI cardiac imaging app that runs on iPhone and iPad with Butterfly Network iQ+ and iQ3 handheld ultrasound probes, giving any healthcare professional real-time probe guidance, automatic diagnostic-quality clip recording and live view validation across the 10 standard transthoracic echocardiographic views (PLAX, PSAX-AV, PSAX-MV, PSAX-PM, A4C, A5C, A2C, A3C, SC-4C, SC-IVC). A second product, HeartFocus Link, adds the same AI guidance to existing cart-based ultrasound systems from GE HealthCare, Philips, Siemens Healthineers, Mindray, FUJIFILM Sonosite, Samsung and Canon over a plain HDMI capture path, for education and training only. DESKi holds two FDA 510(k) clearances (K242807, 2025-04-04; K260780, 2026-06-03, product code QJU) and publishes a Coordinated Vulnerability Disclosure process, a HIPAA & HBNR applicability statement, per-probe list pricing and dated electronic instructions for use. Its only machine-facing integration surface is DICOM: exams are transferred from the mobile app to a customer-configured PACS server (server and client AE titles, host, port, optional TLS), and the DICOM conformance statement and CycloneDX SBOM are available only by emailing support. DESKi publishes no public REST or GraphQL API, no OpenAPI or AsyncAPI specification, no SDK, no CLI, no MCP server and no developer portal; portal.heartfocus.ai is a customer licence-management application, not a developer surface.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles DESKi the way a machine reads it — 4 machine-readable artifacts, 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 — DESKi scores 29.4/100 (thin), with a separate agent-readiness read of 3/100 (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.
Why this profile is thin
DESKi ships regulated end-user software, not a platform: HeartFocus is an FDA-cleared iPhone/iPad app whose only machine-facing interface is a DICOM push to a PACS the customer configures in-app, and the DICOM conformance statement that would describe it is available only by emailing support@deski.ai — /openapi.json, /graphql, /llms.txt and every /.well-known/* path return a real 404 on www.heartfocus.ai and deski.ai, api./developer./link.heartfocus.ai do not resolve in DNS, docs.heartfocus.ai is an S3 bucket returning 403 AccessDenied, and portal.heartfocus.ai is a licence-management SPA that answers 200 with the same 467-byte HTML shell for every path probed.
This is an honest zero, not a gap in our research. DESKi does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

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 DESKi
Each block below is one kind of artifact we hold for DESKi. 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.
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.
Deski Plans Pricing
PLANSRate 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 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 DESKi, 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.
