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 reset field 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
