Example use cases

Journalism: Pull median storage prices for a story on RV ownership inflation. Cite the live data with a hyperlink to the JSON endpoint - readers can click through to verify.
Academic research: Time-series analysis of recreational vehicle storage costs by region. Each pull returns a snapshot tagged with timestamp; multiple pulls over time give you the longitudinal data.
App developers: Building an RV trip planner that surfaces storage options at each stop. Use /data/cost-aggregates.json to show typical pricing alongside our directory listings.
Insurance modelers: Calibrate vehicle-storage liability premiums by region using verified market pricing. Free for non-commercial calibration; commercial integration requires partnership conversation.
Real estate / development: Site-selection analysis for new storage facility builds. The per-(state, category) aggregates show market-by-market median rates and sample sizes.

Rate limits & access

No authentication required for any endpoint. Endpoints are cached at the CDN edge with 10-minute TTL, so high-volume access is supported without rate limiting at the application layer. Requests serving stale cache continue to return 200 OK with current data while a background refresh runs.

If you need higher granularity (per-zip, per-facility, per-day) or research-tier access (longitudinal data, demographic overlays), email partners@stowhelp.com for the research dataset agreement.
