name: Exonum Node HTTP API
description: The HTTP surface an Exonum node serves. The explorer service exposes REST endpoints under /api/explorer (blocks,
block, transactions, call_status) plus a WebSocket interface for submitting signed transactions and subscribing to block-
and transaction-commit events; the system API plugin exposes node info, stats, peers, consensus status and shutdown under
/api/system on the private HTTP server; built-in services (supervisor, time oracle) expose their own endpoints under /api/services/{service_name}.
Exonum is self-hosted software, so there is no vendor-operated base URL - each operator runs their own node and chooses
its public and private ports.

x-deployment-note: No vendor-hosted base URL exists, and none is asserted here; the documentation demonstrates the API against
a locally run node (public HTTP server 8080, private 8081 in the tutorials).

x-enrichment-notes:
no_openapi: Bitfury publishes no OpenAPI, Swagger, GraphQL or AsyncAPI description for Exonum. Probed /openapi.json, /swagger.json,
/api-docs and /llms.txt on both bitfury.com and exonum.com (all 404 on 2026-07-31); the published reference is hand-written
crate documentation on docs.rs. No spec was authored on the provider's behalf.
no_agent_card: /.well-known/agent-card.json and /.well-known/agent.json return 404 on both hosts; no A2A card exists and
none was written.
no_mcp: No official or community MCP server for Exonum or Bitfury was found, and there is no OpenAPI to derive a candidate
tool list from, so mcp/ was skipped.
no_skills: 'skills/ was skipped by the pipeline rule that agent skills must be grounded in real operationIds from an OpenAPI:
none exists.'
no_idempotency: Exonum documents the opposite of an idempotency contract - transactions carry a seed field expressly to
guarantee non-idempotence - so no Idempotency pointer is emitted.
no_security_program: probe-security-programs.py found no security.txt, no disclosure page and no trust center on 2026-07-31,
so no Security, VulnerabilityDisclosure, TrustCenter or Compliance pointer is emitted.
no_well_known: Every /.well-known/ path probed returned 404 on both hosts; well-known/ holds the probe record only and carries
no WellKnown pointer.
