Developer API
One API for every AI capability
OpenAI-compatible chat and reasoning, plus embeddings, reranking, OCR, speech-to-text, scraping, and live web search. EU-hosted, renewable-powered, and private. One key for all of it.
Capabilities
Everything in one API
Every GreenPT capability is reachable through the same OpenAI-compatible API and a single key. Explore each below, or jump straight into the docs.
-
Chat Completions
OpenAI-compatible /v1/chat/completions for European open-weight language and reasoning models.
(opens in a new tab) -
Streaming
Token-by-token responses over server-sent events for real-time chat and agents.

Document OCR
Convert PDFs, Office files, and images into clean Markdown, JSON, or HTML.
-
Speech-to-Text
Transcribe pre-recorded files or live audio streams, multilingual and accurate.
-
Scraper
Extract clean, structured content from any web page in a single call.
-
Websearch
Run a live web search and get ranked results already scraped into AI-ready Markdown.

Why GreenPT
The European AI API without the tradeoffs
Most AI APIs route your data through infrastructure you do not control and bill you for compute whose carbon cost stays hidden. GreenPT runs open-weight models on private, EU-hosted, renewable-powered infrastructure, and never trains on your data.
-
OpenAI-compatible: switch the base URL and key, keep your existing SDKs.
-
One key for chat, embeddings, reranking, OCR, speech, scraping, and search.
-
EU-hosted and GDPR-aligned, your data never leaves Europe.
-
Open-weight, self-hosted models: no lock-in to a closed provider.
-
The Green Router picks the most efficient model for each request.
-
100% renewable-powered, with the carbon cost made transparent.
Performance metrics
GreenPT's data centres deliver a PUE of 1.25 (versus the industry average of 1.55) and a WUE of 0.25 (compared with the sector's 1.8), indicating markedly higher power and water efficiency. All of the electricity is from renewable sources, 100% versus the typical 60% share in the industry.
- 1.25 PUE Sector average 1.55
- 0.25 WUE Sector average 1.8
- 100% Green energy Sector average 60%
The API, in short
Is the API OpenAI-compatible?
Yes. Chat completions follow the OpenAI /v1/chat/completions schema, so most existing SDKs and tools work by changing the base URL and key. Embeddings, reranking, OCR, speech-to-text, scraping, and web search are available through the same API.
What can I build with it?
Chat and reasoning, semantic search and RAG with embeddings and reranking, document OCR, speech-to-text, web scraping, live web search, and code generation. One key covers every capability.
Where is it hosted, and is my data private?
The API runs on private, EU-hosted, renewable-powered infrastructure. Models are open-weight and self-hosted, your data stays in the EU, and it is never used to train models.
Which models are available?
Open-weight language, reasoning, embedding, reranking, and speech models, served from a single catalog. The Green Router can pick the most efficient model for each request automatically.
