We check VATlayer's listed URL (https://vatlayer.com/?utm_source=Github&utm_medium=Referral&utm_campaign=Public-apis-repo-Best-sellers) once a day. History started when VATlayer was first checked, so new entries show fewer than 30 days.
VATlayer API not working for you?
- VATlayer needs an API key. A 401 or 403 usually means a missing, expired or mis-sent credential: check whether it belongs in a header or the query string.
- A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header.
- If calls fail only in the browser with a CORS error, VATlayer may not allow cross-origin requests. Call it from your server instead.
- If it works from one network but not another, check firewalls, VPNs and regional blocks.
- Check the provider's documentation, status page or social accounts for planned maintenance or a changed endpoint.
