May
May is a French digital-health company, operated by LN CARE SAS, whose mobile app supports future and new parents from fertility and pregnancy through the first years of a child's life. It pairs a medical messaging service staffed by French-qualified midwives, pediatric nurses and doctors — answering questions seven days a week from 8am to 10pm — with an expert-reviewed content library, roughly hour-long audio masterclasses, everyday tracking tools for sleep, feeding and weight, and Mya, an in-app AI medical assistant. Founded in Paris in 2020 by Cécilia Creuzet, Antoine Creuzet and Adrien Brunet, it reported more than 400,000 users and a team of around 80 health professionals, raised €7M in September 2024 to expand into Spain and the United Kingdom, and also sells a parental-support benefit to employers. It was surfaced as a portfolio company of Serena and profiled in the API Evangelist network; it publishes a consumer marketing site, a blog and an Intercom help center, but no public developer program, no API reference and no machine-readable API contract of any kind.
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 May the way a machine reads it — 3 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 — May scores 13.0/100 (emerging), 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
May is a direct-to-consumer mobile health app for parents — the whole public surface is a 51-page WordPress marketing site in three locales plus a seven-collection Intercom help center whose only partner-facing section routes health professionals, press and partnerships to an email conversation, and the sole backend hostname in the company's public DNS (capig.may.app, found in certificate-transparency logs) is a dangling CNAME to a deleted AWS Kubernetes ingress load balancer in eu-west-3.
This is an honest zero, not a gap in our research. May 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 May
Each block below is one kind of artifact we hold for May. 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.

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 1
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 May, 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.
