Common Errors & Troubleshooting

Empty domains array The zone or domain keyword returns no matches
✓ Try without the zone filter first, or broaden your keyword to a single short word.
429 Too Many Requests The free tier has a rate limit of roughly 10 requests per minute
✓ Add a delay between calls. For bulk lookups, cache results and avoid re-fetching the same domains.
Slow response times Large result sets can take several seconds to return
✓ Use the limit parameter (e.g. &limit=20) to cap results and improve response speed.
