Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/econ-cpi/briefWhen to prefer
Choose this endpoint when you need a human-readable, narrative interpretation of recent CPI-U inflation trends rather than raw data points. Ideal for agents that need to explain economic conditions to end users in plain language. Prefer over sibling raw-data endpoints when the goal is communication or summarization rather than numerical analysis.
Side effects
- No recent CPI data available — returns empty or minimal brief
- Invalid 'since' datetime format returns a 400 error
- Payment not provided or insufficient — returns 402 Payment Required
- Upstream BLS data unavailable — brief may reflect stale data
- LLM generation failure — may fall back to template-based output
