How this service works
Use when you need housing supply for the McAllen-Edinburg-Mission and Brownsville-Harlingen metros (months of supply, inventory, days on market, homes sold) by week, to judge whether the market is oversupplied before building, lending or buying.
Output
Returns a JSON object containing an array of rows, each with: geographic area, metric name (e.g. months_of_supply), numeric value, unit, as-of date, age in days, staleness flag, data source, reporting cadence, and week ID. Also includes query echo, series name, total rows returned, publisher info, disclaimer, latest available week, and schema version.
Example use cases
Tracking South Texas housing inventory trends
“Show me the months of supply for the McAllen-Edinburg-Mission area over the past three months — I want to see whether inventory is building up or getting absorbed faster.”
Real estate market brief for a developer
“Get me the latest absorption rate data for both the McAllen and Brownsville metros from Frontera Signal so I can understand the current supply-demand balance before we break ground.”
Automated weekly market monitor
“Every Monday, pull the Frontera Signal absorption series for South Texas and flag any weeks where the months-of-supply metric is marked stale or the value jumped more than 10% week-over-week.”
Technical details
Endpoint
GEThttps://fronterasignal.com/api/v1/series/absorption?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need hyperlocal South Texas (Hidalgo and Cameron counties) housing absorption and inventory metrics with weekly granularity and explicit staleness tracking. It is ideal for real estate agents, developers, and researchers focused on the Rio Grande Valley who need affordable, structured, bilingual market data rather than national aggregates from Zillow or Redfin's own UI.
Side effects
- Invalid ISO week format in 'from' or 'to' parameters returns a 400 error
- Requesting a week range beyond available data returns an empty rows array
- Stale flag (stale: true) indicates data is older than the freshness threshold (14 days for weekly, longer for monthly)
- Payment failure via x402 protocol blocks access and returns a 402 response
- No rows returned if the requested week range precedes the series start date
