Agent monitors flight cancellations for pennies using Mercator travel API in Grok Bot
jeff_weinstein · x · 2026-09-27
A user built a flight monitor for Boston and Toronto traffic inside Grok Bot using Mercator, a pay-per-call travel data aggregator. Similar to Flighty's status updates, it predicts cancellations every 30 minutes for just a few cents. Mercator unifies cash fares, award inventory (Seats.aero), flight conditions (FlightAware), and more via MCP/x402, letting agents chain calls per query (e.g., a sample business-class comparison call cost $0.021).
