Technical details
Endpoint
GEThttps://api.lastlookdata.com/api/bundle/mortgage-pulseWhen to prefer
Use this endpoint when you need a single-call snapshot of the entire US mortgage market — including rates, housing fundamentals, and rate trend — rather than querying individual FRED series separately. Ideal for mortgage market briefings, housing affordability analysis, or LLM context injection requiring multiple correlated indicators at once.
Side effects
- Data source temporarily unavailable from FRED or upstream provider — may return 503 or stale data
- Payment of 0.4 USDC not fulfilled via x402 — returns 402 Payment Required
- Rate limiting or abuse detection — returns 429 Too Many Requests
- Unexpected schema change in upstream FRED data — partial or malformed response
