Cardano

Cardano is a proof-of-stake blockchain platform designed for secure and scalable decentralized applications and smart contracts. Developer API access to the Cardano network is provided primarily through Blockfrost, a hosted REST API service that exposes over 100 endpoints covering transactions, addresses, assets, blocks, epochs, stake pools, governance, scripts, metadata, and mempool data. Authentication uses project-scoped API keys passed as HTTP headers. Blockfrost operates on Cardano Mainnet, Preview, and Pre-Production testnets, and also supports IPFS storage and the Milkomeda sidechain. SDKs are available for 15+ programming languages.

Cardano publishes 20 APIs on the APIs.io network, including Cardano » Accounts API, Cardano » Addresses API, Cardano » Assets API, and 17 more. Tagged areas include Blockchain, Cryptocurrency, Proof-of-Stake, Smart Contracts, and Web3.

The Cardano catalog on APIs.io includes 2 JSON-LD contexts and 1 Spectral governance ruleset.

Cardano’s developer surface includes authentication, engineering blog, and 2 more developer resources.

    files via the InterPlanetary File System. The IPFS API base URL is https://ipfs.blockfrost.io/api/v0 and uses the same

    the free Starter tier to 50,000 MB on the Developer tier.

  - Pin NFT metadata and media files referenced in Cardano native asset policies
  - Store off-chain data linked from on-chain transaction metadata
