What It Is

contratos-menores.es is an open-data analytics project focused on “Contratos Menores” — small public contracts — in the Madrid region of Spain. According to the site, the author downloaded and cleaned more than 2.53 million publicly released small-contract records from 2016 to 2020. The goal is to turn information that was originally scattered, error-prone, and difficult to analyze into a more accessible, visual, and interpretable data tool.

Core Features and Data

The page currently highlights interactive tables for viewing annual cumulative contract amounts by public entity and supplier, as well as map-based visualizations related to entities in the Madrid health system. Planned features include a contract search engine, clustering of similar contracts, detection of potentially split contracts, analysis of recurring and predictable spending, detailed contextual comparisons, integration with external open data, and extraction of data from PDFs. The primary data source is quarterly small-contract lists published by public administrations, totaling 2,537,206 records and covering the Madrid region from 2016 to 2020.

Pricing, Platform, and Integrations

The page does not mention commercial subscriptions, paid plans, or payment methods. On the contrary, the project states that its resulting datasets will be free to query and reuse, and that the code is planned to be released as open source on GitHub. At present, it mainly appears to be a web-based interactive tool, with no indication of an API, account system, or formal technical support. Future plans include connecting other open-data sources, public PDFs, company information, budgets, and data on political officials.

Pros and Cons

Its strengths are the large dataset and clearly defined subject matter, making it useful for public procurement oversight, media investigations, and fact-checking. Its visualization, similarity analysis, and machine-learning direction also give it strong research value. The drawbacks are that many features are still planned or “coming soon,” the geographic and time coverage is limited, and the site is in Spanish. For marketing or SEO use cases, it does not provide keyword research, rank tracking, backlink analysis, or site audits, so it should not be treated as a conventional SEO tool.

Who It’s For and Access from China

It is best suited to journalists, transparency organizations, public policy researchers, data science learners, and civic oversight teams interested in Spanish public procurement. The page does not provide information about access from mainland China, so real-world connectivity needs to be tested independently; payment availability is also not applicable or unclear. If the goal is marketing or SEO, alternatives such as Ahrefs, SEMrush, and Similarweb would be more appropriate. If the goal is public data analysis, government open-data portals and public procurement data platforms are more relevant references.
