How this service works
Period-over-period change across key macro indicators
Output
Returns a structured object showing period-over-period deltas for one or more macro series (e.g. CPI, GDP, unemployment, federal funds rate). Each entry includes the current and prior period values, the absolute and/or percentage change, and timestamps. If no series is specified, returns deltas for 8 default key macro indicators.
Example use cases
Example prompt
“Show me the period-over-period changes in inflation and unemployment over the last 8 periods so I can see the trend direction.”
Technical details
Endpoint
GEThttps://web-production-60258.up.railway.app/macro/deltaWhen to prefer
Use this endpoint when you need to understand how macro indicators have changed over time — not just current values — especially for trend analysis, economic monitoring, or comparative reports. Prefer this over the raw FRED series endpoint when you want pre-computed deltas rather than raw level data, and over the all-indicators snapshot endpoint when period-over-period change is specifically required.
Side effects
- Invalid or unrecognized FRED series ID or name returns an error or empty result
- Periods value exceeding max of 24 may be rejected or clamped
- Series with insufficient historical data may return partial results
- Payment failure (402) if x402 payment header is missing or insufficient
- Rate limiting or upstream FRED API unavailability may cause 5xx errors
