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 2 APIs on the APIs.io network: RPC Node API and Automation API. Tagged areas include Blockchain, Layer 1, Oracles, Web3, and Market Data.

Supra’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, authentication, CLI, and 23 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.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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/. 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. Want it done for you? Prioritized profiling — $2,500 →
