Preply

Preply is a global online language-learning marketplace that connects learners with private tutors across dozens of languages, offering one-on-one video lessons, flexible scheduling and a satisfaction-backed tutor-replacement guarantee. Alongside its consumer marketplace, Preply runs Preply Business, an enterprise language-training offering with SSO, automated user provisioning and LMS integrations. Preply exposes a small public, unauthenticated tutor-search API (originally published as an OpenAI/ChatGPT plugin) that lets applications and agents search tutors by subject, price, availability and language and fetch individual tutor profiles. This profile was enriched by the API Evangelist pipeline from Preply's public surface.

Preply publishes 1 API on the APIs.io network: Chatgpt Openapi API. Tagged areas include Company, Education, Language Learning, Tutoring, and Marketplace.

Preply’s developer surface includes engineering blog, support, and 16 more developer resources.

Kin Score Kin Score How this is scored →
scored 2026-09-08 · rubric v0.20.0
Regulatory Posture applies to this provider. Its tags matched the Education & Research regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/preply: open an issue to ask a question, or submit a pull request to add artifacts.
