Linguidoor
Linguidoor is a Berlin-based, ISO-branded human translation and localization agency serving businesses and individuals across Germany and internationally. It offers professional translation in 100+ languages, website / app / software / game localization, MTPE, certified and sworn document translation for German administrative processes (birth and marriage certificates, driving licences, Anmeldung, Schufa, diplomas), interpretation, subtitling and captioning, voice-over and dubbing, transcription, desktop publishing, content writing, international SEO, and AI data services (data annotation, tagging and labeling, voice and text data collection, text-to-speech and voice cloning). Pricing is published per translated word across three service tiers, with fixed-price certified document translations sold through an online shop. Linguidoor publishes NO developer program: enrichment found no OpenAPI, AsyncAPI, GraphQL, MCP server, agent card, SDK, CLI or API documentation of any kind. The site is WordPress + WooCommerce on Hostinger; its only machine-readable surfaces are the platform-default WordPress REST API at /wp-json/ (which includes the public unauthenticated WooCommerce Store API) and a plugin-generated llms.txt whose entire content is the default WordPress "Hello world!" post.
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 Linguidoor the way a machine reads it — 4 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 — Linguidoor scores 24.2/100 (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
Linguidoor sells human translation and localization as a service, not software — /api, /docs, /developers, /openapi.json, /swagger.json, /graphql and every /.well-known/ path return the WordPress 404 page, and the only machine-readable things on the host are the platform-default WordPress/WooCommerce REST API at /wp-json/ and a Hostinger-plugin llms.txt whose entire body is the default WordPress "Hello world!" post.
This is an honest zero, not a gap in our research. Linguidoor does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

How we profile Linguidoor
Each block below is one kind of artifact we hold for Linguidoor. 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.
Linguidoor Agent Discovery
Agent-native content-discovery surface for Linguidoor. The only artifact is an llms.txt file served at https://linguidoor.com/llms.txt (HTTP 200, text/plain, 225 bytes), generat...
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 six things the Kin Score reads for commercial clarity.
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.

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 Linguidoor, 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.
