used-car-market-comparison
Used-car market comparison
Build a traceable comparison of advertised vehicles. An asking-price sample can show how a listing compares with observed alternatives; it cannot establish a transaction value, sale speed, or the vehicle's mechanical condition.
Setup and API contract
Set CRAWLORA_API_KEY to your key from crawlora.net.
Use the bundled scripts/crawlora.sh, which sends x-api-key to
https://api.crawlora.net/api/v1. Read reference/endpoints.md
for selected endpoints and parameters. Successful results are inside data;
check application code as well as HTTP status. Stop on authentication errors,
back off on 429, and retry a transient upstream failure once. A failed fetch
is unavailable evidence, not zero inventory. Keep requests within the user's
scope and credit budget; save query, page, source IDs, and retrieval times with
results if collection needs to resume.
