Supra

Supra is a vertically integrated Layer 1 blockchain developed by the Swiss-based Entropy Foundation, combining a MultiVM execution layer (MoveVM plus an EVM) with services that most chains outsource: DORA native oracle price feeds (push and pull), decentralized verifiable randomness (dVRF), protocol-level automation (AutoFi), on-chain technical indicators and indices, and the SupraNova / HyperNova cross-chain bridge. Developers reach the network through a public, keyless REST + JSON node API at rpc-mainnet.supra.com that publishes a live OpenAPI 3.1 description covering 56 operations across accounts, transactions, blocks, events, view functions, tables and inclusion proofs, plus a JSON-RPC WebSocket subscription stream for newly committed blocks. Market data is served separately by an API-key-gated Price Feeds REST and WebSocket API for real-time and historical OHLC data. Supra is headquartered in Miami, Florida and was founded in 2019.

Supra publishes 11 APIs on the APIs.io network, including Accounts API, Block API, Consensus API, and 8 more. Tagged areas include Blockchain, Layer 1, Oracle, Web3, and Market Data.

Supra’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, authentication, CLI, and 24 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data 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/supra: open an issue to ask a question, or submit a pull request to add artifacts.
