Technical details
Endpoint
POSThttps://api.vextorium.com/v1/us-mortgage-rates?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, weekly US mortgage rate benchmarks specifically from the Freddie Mac PMMS — the most widely cited mortgage rate survey in the US. Prefer this over scraping news sources or using bank-specific rate APIs when you need standardized 30-year and 15-year fixed rate benchmarks with historical series for trend analysis, financial dashboards, or real estate research.
Side effects
- Survey data not yet published for the current week (Freddie Mac publishes Thursdays) — may return prior week's data
- Invalid or missing 'weeks' parameter may return a default series length
- Network or upstream data source unavailability returns an error response
- Requesting far-future or very distant historical weeks may return null series entries
