A few questions on Stash data

Hi [first name] — thanks for taking the time.

I'm Luke, founder of FlipStack, an Australian platform for renovation flippers. I'm evaluating Stash as our primary property-data provider, and I've already worked through your v2 data API — so I'm across the endpoints. The questions below are the things I couldn't determine from the documentation: coverage, licensing and commercial terms.

No rush at all — please answer whatever you can in your own time. There's a quick button for a fast answer and a context box on each question for anything that needs a fuller explanation.

Coverage & data quality
1.How complete and current is your sold-sales data in Western Australia — metro Perth in particular — relative to the eastern states?
WA is our launch market, so this matters most to us.
2.How far back does your historical image archive go? For a typical WA property, roughly how many past listing campaigns carry photos?
We use historical listing imagery to understand a property's condition over time.
3.How complete and how frequently updated are your development-application, BCI and listing-history feeds — particularly in WA?
Licensing & data rights
4.Does your licence permit a derived, resold product — where we transform and resurface your data inside a paid SaaS, and sell a derived report to our users?
This is fundamental to how our product works, so we'd want it confirmed in writing.
5.Does your licence allow us to cache responses server-side and retain derived signals over time?
We cache to manage cost and latency.
6.Are there attribution requirements, and on cancellation, what are we required to delete?
Commercial & access
7.How is access priced — per call, per seat, or committed volume — and what does each dataTier cost? Is there a minimum spend?
8.Can you provide a sandbox or test key with real WA data we can validate against, and is access time-limited?
We'd like to validate against our own benchmarks before progressing.
9.As our user base grows, is there a partnership path on terms — and do you offer anything for early reference customers?
Reliability & roadmap
10.What are your uptime, rate-limit and support arrangements for an integrator of our size?
11.Is the AVM production-grade, and when do you expect the AI listing search (the _ai-beta endpoint) to reach general availability?
One technical detail
12.For comparable-sales search, what does the filters array support for geo selection — a radius around a point, a bounding box, or another method?
We pull comparable sales around a subject property — happy for your team to field this one.
