# Cardano (ADA) ## Cardano (ADA) Documentation with NOWNodes The **Cardano API** provides a structured way to interact with the **Cardano (ADA) blockchain**, enabling developers to access blocks, UTXOs, stake data, accounts, and network information while also supporting transaction construction and submission through various ecosystem-standard interfaces. The Cardano API allows efficient interaction with blockchain resources, and this doc serves as an overview for developers searching for Cardano docs, api docs, submit transaction, and integration for web applications.\ \ Through **NOWNodes**, developers gain high-availability access to **Cardano Mainnet** without deploying or managing their own node infrastructure. The platform ensures stable performance, scalable throughput, and straightforward integration into your code, applications, and web services, supporting a wide range of Cardano-based development workflows. ### NOWNodes Cardano (ADA) Interfaces * **Cardano Rosetta API** – Provides standardized blockchain data, balance queries, UTXO access, and transaction construction using the Rosetta specification for multi-chain interoperability. * **Cardano Blockfrost API** – Offers detailed blockchain insights including blocks, addresses, assets, metadata, and transaction submission aligned with the Blockfrost schema. * **Cardano Index API** – Delivers indexed and optimized blockchain data for fast lookups, historical queries, and analytical use cases. * **Cardano Ogmios WebSocket (WSS)** – A low-latency WebSocket interface enabling real-time chain synchronization, event streaming, and high-performance transaction workflows. Using the **Cardano API docs with NOWNodes**, developers can efficiently **integrate** Cardano into any **application**, **leveraging multiple interface standards** to match their architecture. The documentation provides complete guidance for working with the network’s UTXO model, Rosetta semantics, Blockfrost endpoints, and Ogmios streaming, ensuring full support for code-level implementation and production-ready workflows. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://nownodes.gitbook.io/ada-cardano-1/cardano-ada.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
