Example use cases
Weekly economic release preview
“What major economic data releases are scheduled in the coming days? Show me the next 15 events from the macro calendar so I can plan around them.”
Pre-market morning briefing

Research report event tracking

Technical details
Endpoint
POSThttps://fathom-opal.vercel.app/api/calendarWhen to prefer
Use this endpoint when you need to discover upcoming scheduled macroeconomic data release events (e.g., GDP, CPI, unemployment, FOMC decisions) rather than fetching historical time-series values. It is ideal for economic calendars, pre-market briefings, or scheduling workflows around data releases. Prefer this over general FRED time-series queries when the goal is 'what is coming next' rather than 'what happened historically'.
Side effects
- Invalid limit parameter type (must be a string representation of an integer)
- Empty events array if no upcoming events are scheduled in the data feed
- Payment failure if x402 USDC payment of $0.08 is not processed correctly
- Service unavailability on Vercel deployment causing 5xx errors
- FRED upstream data outage causing stale or missing calendar data
