About blockfrost Cardano

Blockfrost provides an API for interacting with the Cardano blockchain, offering over 100 endpoints for building decentralized applications, submitting transactions, and querying blockchain data. It also supports Midnight, Cardano's privacy-focused partner chain, allowing queries against blocks, transactions, and smart contracts on that network. Additional services include webhooks for real-time event notifications and IPFS-based decentralized file storage.

The platform provides SDKs for a range of programming languages, including Node.js, Python, Rust, C#, Go, Haskell, Ruby, Swift, Kotlin, Elixir, Java, Scala, PHP, and Arduino, along with an OpenAPI specification. Its tools, SDKs, and backend are open source.

Blockfrost offers a free Starter plan with 50,000 requests per day, 100 MB of IPFS storage, and access to one project and one webhook. Paid tiers include Hobby (EUR 29/month) with 300,000 requests per day and 3 projects, and Developer (EUR 79/month) with 1,000,000 requests per day, 10 projects, 2 workspaces, access filters, and premium transaction submission with priority mempool and rollback protection. An Enterprise plan offers custom limits, infrastructure, rate limiting, and SLA. Yearly billing offers a 15% discount on paid plans. Support is available around the clock.
