  The provider publishes no dedicated changelog page (/changelog returns the homepage SPA shell). Dated
  change statements were read from the machine-readable surfaces the provider does publish:
  https://api.onchainagentintel.io/agent.json (service descriptions carry a dated breaking-change note),
  https://onchainagentintel.io/.well-known/x402.json (per-resource lastUpdated), the OpenAPI info.version,
  the MCP serverInfo, and https://onchainagentintel.io/llms.txt (measurement-window dates). The Atom feed
  at /feed.xml is editorial (State of ERC-8004 posts), not an API changelog, and is not mirrored here.
