Klarys
Klarys — formerly ProcSea, renamed in 2023 — is a French SaaS eProcurement platform built for the fresh-food supply chain: seafood, fruit and vegetables, meat and dairy. It connects retail, wholesale and foodservice buyers with their suppliers, wholesalers and mareyeurs through a standardized fresh-food product catalog, a supplier sales interface, a centralized purchasing interface, a central purchasing module for store networks, a supplier invoicing module and a business-intelligence module. Klarys states that the platform "integrates with all your business systems and applications via API and EDI" — ERP, accounting tools and product reference systems. Founded in 2016 in Rennes, France with operations in Switzerland, it is a Serena portfolio company, a member of the SAP.iO acceleration program and listed on the SAP Store. The tenant application runs at klarys.app and publishes an RFC 8414 OAuth 2.0 authorization-server metadata document anonymously — including mcp:read and mcp:write scopes — but no public API reference, OpenAPI, or developer portal: the schema endpoint requires an authenticated tenant account.
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 Klarys the way a machine reads it — 6 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 — Klarys scores 23.4/100 (emerging), with a separate agent-readiness read of 21/100 (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.
Why this profile is thin
Klarys runs a Django REST Framework API with a live OpenAPI schema endpoint, but https://klarys.app/api/schema/?format=json answers HTTP 401 {"code":1003,"error":"User is unauthenticated"} with Content-Type application/vnd.oai.openapi+json — the spec is real and served only to an authenticated tenant, and there is no developer portal, API reference or pricing page anywhere on www.klarys.io (all 134 sitemap URLs walked).
An API exists — we simply could not reach the contract without credentials or a sales conversation. This one is Klarys's to change: publishing the reference and a machine-readable spec at a public URL, while keeping key issuance behind whatever gate they like, would let an integrator evaluate the API before committing to a call.

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 Klarys
Each block below is one kind of artifact we hold for Klarys. 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.

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.
Klarys 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.
Klarys 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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.

This is an independent, third-party profile of Klarys, 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.
