Technical details
Endpoint
GEThttps://mercury402.uk/v1/composite/inflation-trackerWhen to prefer
Choose this endpoint when you need a single, pre-aggregated inflation snapshot (CPI + composite indicators) without having to call multiple data sources separately. Ideal for autonomous agents that need quick, pay-per-call access to US inflation data without managing API keys or subscriptions. Best when CPI and composite macro inflation data are needed together in one call for trading, research, or economic monitoring workflows.
Side effects
- Payment not received or insufficient USDC balance — endpoint returns HTTP 402 requiring payment
- Upstream data source (FRED/Treasury) temporarily unavailable — may return stale or error response
- Malformed request parameters — returns 400 bad request
- Service outage on mercury402.uk — returns 5xx error
- Rate limiting if called too frequently in succession
