About each API
ProblemsByVin API
Owner complaints, recalls and failure-mileage statistics by vehicle make, model and year.
Free, downloadable datasets derived from 78,000+ NHTSA owner complaints and 4,900+ recalls: failure-mileage quartiles, post-warranty failure patterns, recall gaps, and engine/transmission complaint density. CSV + JSON, CC BY 4.0.
Strengths
- No API key needed
- Callable from the browser (CORS)
- HTTPS
How to choose between them
- Prototyping or a tutorial? Pick the one that needs no API key (both qualify).
- Calling from a web page? You need CORS. Otherwise route requests through your own server or a serverless function.
- Going to production? Favour HTTPS, a strong uptime record and a provider with clear rate limits and terms. Check each API's docs before you commit.
- Still unsure? Both are free to try: send one request to each and compare the data you get back.
