Supra RPC Node API

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.

Where this information came from

This is an independent, third-party profile of Supra RPC Node API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
