After your execution: reconcile_execution compares supplied fills with that baseline. Read-only snapshots, no orders or custody. Start with get_agent_manifest (free) and choose journeys_v1 by intent. Daily MCP trial: one free call per paid tool and per token per client each UTC day. Four tools x seven tokens = up to 28 independent trials; then 0.001 USDC per call.
