  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.

- name: Supra RPC Node API
  description: >-
    Public, keyless REST + JSON API served by every Supra RPC node. Covers accounts (resources, modules, coin and
    fungible-asset statements), transaction submission and simulation, gas price estimation, blocks and consensus
    blocks, events, Move view function execution, table item lookup, committee authorizations and event-emission /
    transaction-inclusion proofs, across four coexisting path versions (v1 through v4). Also exposes a JSON-RPC
    WebSocket upgrade at /rpc/v4/ws for newBlocks and newBlockHeaders subscriptions. Described by an OpenAPI 3.1.0
    document the node itself serves at /docs/api.json.

  description: >-
    Oracle market-data REST API returning the latest price for a trading pair and historical OHLC candles for up to
    one month, on the DORA data feeds Supra publishes on-chain. Two documented endpoints, GET /latest and
    GET /history. Requires an x-api-key header; keys are issued by request form, and the surface is documented as
    Early Access.

- name: Supra Price Feeds WebSocket API
  description: >-
    Streaming oracle market-data API. Clients open a WebSocket to wss://prod-kline-ws.supra.com with an x-api-key
    header and send a subscribe action naming the ohlc_datafeed channel, a resolution in minutes, and a list of
    trading pairs; the server pushes an OHLC update each interval.

  description: >-
    Read and observation surface for Supra's native on-chain automation (AutoFi) registry. Automation tasks are
    registered and cancelled through the Supra CLI and Move entry functions rather than an HTTP write endpoint;
    execution is observed through the node RPC using the automated_transactions account endpoint and the
    type=auto block filter, and registry state is read through Move view functions.
