Analytics and monitoring decision
CarsDataset
A single developer can build a working, self‑hosted vehicle-specs API in a few weeks, but reproducing the vendor's curated updates, market-pricing feeds, and ongoing data ingestion/coverage is operationally heavier—so keep paying if you need those features and live prices.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Provide vehicle spec lookups and CSV/SQL exports via a simple REST API backed by an imported dataset
What it still won’t have
- Quarterly curated updates and dataset hygiene provided by vendor
- Real-time market price listings and Fair Price API
- Legal license/reselling rights and vendor support
- Geographically sourced pricing coverage and continuous ingestion from multiple marketplaces
- SLA, analytics dashboards, and built-in rate-limited multi-tenant API
What remains hard
- Product polish and ongoing maintenance
First-year cost

Runnable build prompt
Build a self-hosted vehicle-specs REST API using Python (FastAPI), Postgres, and Docker. Core features in scope: import vendor CSV/JSON into a Postgres schema with indexes; implement endpoints GET /search (filters: brand, model, year_min/year_max, power_min/power_max, page/page_size), GET /vehicle/{id}, GET /brands, GET /models?brand=; support JSON responses and CSV export endpoint; require API key in X-API-Key header and implement simple per-key rate limiting and request logging; include pagination, input validation, error handling, and unit tests for ingestion and API handlers. Out of scope: building marketplace price ingestion, continuous multi-source scrapers, paid license handling, or UI client. Provide a README with startup steps and Docker Compose for Postgres and the API.How we checked

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
