Agent Nexus (agentnexus.app)

Resolves a capability need into a callable interface: HTTP APIs, MCP servers and CLIs, each with a machine contract and live reliability data.

Card-drift history

Watching this agent since 2026-09-16T13:19:58Z. Hash = SHA-256 (16 hex) of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only edits don't count as drift. Feed: api/a2a-drift.json.
