What It Is

Built on Cardano is a project discovery and organized directory for the Cardano ecosystem. The text explicitly states that its goal is to “help foster discovery in, and exploration of, the Cardano ecosystem.” Based on the crawled content, many parts of the site currently show 404 pages, but it still exposes documentation for the Cardano Ecosystem API. For that reason, it is better evaluated as an ecosystem data source or project indexing tool rather than a full-fledged enterprise SaaS platform.

Core Features and API

Its core capabilities revolve around querying project data: /projects returns all projects sorted by most recently updated, including logo, name, industry, description, and links; /projectName?slug={slug} retrieves a single project by slug; /projectsByTerm?term={term} filters by tag or term, such as wallets; and /projects-by-epoch returns growth data for industry terms across epochs. The API Base URL is hosted on Google Cloud Functions, and users are required to attribute and link all data. The total request limit is 1000 requests per day.

Pricing, Collaboration, and Security

The text does not disclose plans, pricing, payment methods, or free/paid versions. The only confirmed limitation is the API’s daily cap of 1000 requests. There is also no information about team collaboration, role-based permissions, audit logs, SSO, data security compliance, SLAs, or customer support. Therefore, if it is to be used in an enterprise production system, stability, licensing terms, and the data update mechanism should be confirmed separately.

Pros and Cons

Its advantages are its vertical focus and simple API, making it suitable for developers who want to quickly embed a Cardano project directory into an app or research tool. The returned fields also cover the basic information needed to display projects. The drawbacks are that much of the crawled site content returns 404, public information is limited, the API quota is low, and there is no clear documentation on authentication, versioning, error codes, SLAs, or commercial support. It is not suitable as a direct dependency for high-concurrency or strict-compliance scenarios.

Who It’s For and Access from China

It is suitable for Cardano ecosystem researchers, developers, project teams, and product teams building ecosystem navigation tools. Access from China cannot be determined from the text, and payment methods are not disclosed. If access or stability is limited, Cardano official resources, GitHub project lists, blockchain data platforms, or other crypto ecosystem directories may be considered as alternative data sources.
