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 21 APIs on the APIs.io network, including » Accounts API, » Addresses API, » Assets API, and 18 more. Tagged areas include Cardano, Blockchain, Cryptocurrency, Proof of Stake, and Smart Contracts.

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.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cardano: open an issue to ask a question, or submit a pull request to add artifacts.

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