Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/econ-mortgage/briefWhen to prefer
Use this endpoint when you need a human-readable, narrative interpretation of 30-year fixed mortgage rate trends rather than raw rate data. Ideal for generating user-facing reports, economic digests, or agent responses that need plain-English explanation of mortgage market movement. Prefer this over raw data feeds when the goal is to communicate trends conversationally.
Side effects
- No rate change data available for the requested window — returns brief based on zero changes
- Invalid 'since' date-time format causes a 400 error
- Payment of 0.25 USDC not fulfilled — returns 402 Payment Required
- Service unavailable or Railway infrastructure outage — returns 5xx error
- Window start date too far in the past may return limited or empty data
