description: 'Vapor IO is an Austin, Texas edge computing company that builds and operates
  the Kinetic Grid, a carrier-neutral network of micro modular data centers offering
  edge colocation, interconnection, networking and network-delivered AI across dozens
  of US markets and, through a Cellnex partnership, into Europe. Its public, machine-readable
  developer surface is the open source Synse platform, published under the vapor-ware
  GitHub organization: Synse Server, a uniform HTTP and WebSocket API for monitoring
  and controlling physical and virtual devices (data center equipment, IoT devices,
  building management systems, edge hardware), and the Synse plugin gRPC API, whose
  Protocol Buffers contract is published in full. Protocol-specific plugins cover IPMI,
  SNMP, Modbus over TCP/IP, Intel AMT and Juniper JTI, with Go and Python SDKs, a Go
  CLI, Helm charts and Docker images. Kinetic Grid Portal telemetry is described as
  API-accessible but is documented only to customers.'

  name: Synse Server API (v3)
  description: 'Synse Server exposes a uniform HTTP and WebSocket API for reading from
    and writing to physical and virtual devices through protocol-specific plugins.
    The same 18 operations are available over both transports: status, version, config,
    plugin summary/detail/health, device scan, tags, device info, read, read-by-device,
    read cache, streamed readings (WebSocket only), asynchronous and synchronous writes,
    and transaction status. Synse Server is self-hosted; the base URL is the host and
    port of the operator''s own deployment, which defaults to port 5000.'

  description: 'The internal gRPC API for bi-directional communication between Synse
    Server and Synse plugins. The published Protocol Buffers contract defines the V3Plugin
    service with 12 RPCs — Devices, Health, Metadata, Read, ReadCache, ReadStream,
    Test, Transaction, Transactions, Version, WriteAsync and WriteSync — six of which
    return server streams, plus 24 messages and three enums. Plugins are self-hosted
    and listen on port 5001 by default.'

  reason: covered
  detail: >-
    Vapor IO publishes a real machine-readable contract — the Synse V3Plugin Protocol Buffers
    file, 12 RPCs, harvested verbatim — plus a complete HTTP/WebSocket API reference, first-party
    Go and Python clients, a Go CLI and container images. No OpenAPI exists anywhere on any host
    or in the vapor-ware organization, so the REST surface is documented in markdown only.
