Common Issues
"API key required" error
Make sure you're including your API key in requests:
# Using header (recommended)
curl -H "X-API-Key: tk_live_your_key" https://api.telco.dev/v1/lookup/4155551234
# Using query parameter
curl "https://api.telco.dev/v1/lookup/4155551234?api_key=tk_live_your_key""Invalid API key" error
- Check that you copied the full API key
- Verify the key is active in your dashboard
- Make sure you're using a live key (
tk_live_...)
"Rate limit exceeded" error
You've hit your rate limit. Options:
- Wait for the limit to reset (check the
resetfield in the error) - Upgrade to a higher tier for more capacity
- Implement caching to reduce API calls
"No data found" for a number
The number may not be in our database. This can happen for:
- Very new number assignments (check back after the next data update)
- Ported numbers (our data shows the original carrier assignment)
- Invalid or non-existent numbers
