Hello, I have been working with open contracting for about 3 years, which is also an open data standard but for tender purchases. I suggest doing a full discovery for the sources, but it is necessary to understand the entire list of sources and the business goals of integration. For any additional questions, please write in private messages. I will be happy to collaborate.

Hello! I will prepare an analytical review based on ~40 sources: what data they provide, access conditions, limits, and authorization schemes (API keys/OAuth2), bulk downloads or REST, and formats CSV/JSON/XML/RDF. I will classify (free/paid/restrictions/licenses) and provide recommendations on integration, caching, and working with rate limits/updates. Which countries are a priority for you and in what format would you prefer to receive the results: a table + report or just a structured table?

Hello, Ihor!
The task is clear — a structured analytical report is needed on approximately 40 open data sources from the EU, focusing on practical integration. This is exactly the kind of research I conduct.
What you will receive as a result:
1. An analytical card for each source (approximately 40 items):
— Types of available data (registration details, beneficiaries, financial indicators, relationships between entities, etc.)
— Formats (JSON, XML, CSV, RDF, bulk download)
— Frequency of data updates
— Authorization method (API key, OAuth 2.0, open access)
— Rate limits and quotas
— Type of license (CC BY, ODbL, PSI/ODD, etc.)
— Direct link to API documentation
2. Classification of sources by access conditions: free / paid / with restrictions / with registration — in a convenient comparison table
3. Practical recommendations for integration:
— Optimal connection methods for each group of sources
— Priority sources to start with
— Libraries and approaches for automating data collection (Python requests, pagination, bulk import)
Submission format: structured report in Google Docs / DOCX + summary table (Google Sheets / Excel) for convenient filtering
Familiar with the PSI/ODD directive, I have practical experience working with REST APIs and open public registers of the EU.
I am ready to discuss the details and clarify the complete list of 40 sources — the exact assessment of the scope depends on it. Please write to me privately.
Best regards,
Roman

Good day
I have experience working with state registries, particularly with data from the cadastre, I have such a project in my portfolio
Overall, I am ready to complete your tasks
Write to me, we will discuss, I will be happy to collaborate!

Hello! Having studied your project with great interest, I am ready to start working on it. Let's discuss the details to achieve the best result.
Budget: 15000 UAH Deadline: 7 days
Good day! My colleague and I have been professionally engaged in the technical design of data collection automation systems and integration with company registries for over 4 years, so we will help your project obtain a clear roadmap for connecting to GLEIF, Companies House, and other European data hubs. We will implement the frontend part of the analytical overview with a detailed description of REST API, OAuth 2.0 protocols, and Bulk Downloads strategies, paying special attention to legal restrictions and commercial limits on the use of aggregators. Our 4 years of experience is confirmed by successful projects drkukharevich.rivne.ua, crave-agency.com.ua, jk-solution.com.ua, where we have already worked with open registries and structures of beneficial ownership. We will ensure technical excellence in execution and offer a research cost starting from $450 depending on the level of detail of technical script examples for each API.

Hello! My partner (designer + full-stack) and I have been specializing in the technical development of complex data collection systems and integration with EU government APIs for over 4 years, so we will professionally conduct a comprehensive study of 40+ sources (data.europa.eu, GLEIF, OpenOwnership, etc.) taking into account the requirements of the Open Data Directive (PSI/ODD). We will develop the architecture of the analytical report in Figma with a focus on technical limits (Rate limits), authorization methods, and comparison of data formats (JSON/RDF/Bulk), ensuring a technically flawless classification of sources by license types and update frequency. Our experience in development is 4 years; take a look at our work in terms of processing large data sets and system automation: hyperfi.tech, espressolab.com.ua, hudi.com.ua. The estimated cost for such an in-depth study is $600 – $1000 with a timeline of 10–14 days.

Good day!
I represent the company Devoxen.
We can conduct an analytical study of open data sources in EU countries with a focus on practical suitability for integration. We have experience working with APIs, open data platforms, documentation, technical access limitations, and preparing structured conclusions for further automation of data collection.
Within such a study, we can process each source separately: types of available data, formats, update frequency, access methods, authorization, technical limits, licensing conditions, and potential usage restrictions. Separately, we can prepare a classification of sources based on access conditions and practical recommendations for integration via API, bulk datasets, or mixed approaches.
On our part, we will prepare a commercial proposal with a clear structure of the study, format of the results, and stages of execution.
We also provide a guarantee: if inaccuracies or deficiencies are found within the agreed scope, we will promptly address everything.
Let's discuss the details in private messages.

Budget: 27000 UAH Deadline: 7 days
Hello! The task is clear — essentially, a structured analytical overview of open data sources from the EU is needed, focusing on practical integration.
I have experience working with REST APIs, Open Data platforms, and documenting technical integrations. I am familiar with the PSI/ODD directive and the main registries (Companies House, GLEIF, OpenOwnership, data.europa.eu).
What I will offer:
Basic package ($600–800, 5–7 days):
An analytical overview of all ~40 sources — types of data, formats, licenses, rate limits, authorization. Classification + final report in PDF/DOCX.
2. Extended ($900–1200, 7–10 days):
The same + working examples of requests to key APIs, code snippets for automation, recommendations for connection architecture.
Send the complete list of sources — I will take a look and provide an accurate estimate. If there is a specific use case (KYC, due diligence, analytics) — this will help prioritize the research.
