The integration
A standard authenticated HTTP request
These examples show different request interfaces. Confirm that the APIs return the information your workflow needs before migrating.

Before you integrate
What should I compare when choosing a phone lookup API?
Compare the fields your workflow needs, country coverage, actual provider responses, and the published terms for the plan you choose. Validation and formatting are different from optional carrier or other intelligence fields.
Do free requests renew every month?
500 requests per application · one-time allowance. This allowance does not renew. Check the plan details before activating a subscription.
Can I try a request before subscribing?
Review the published API documentation and plans on the API page. A public trial is not available here.
Does phone validation prove ownership or deliver messages?
A phone lookup does not prove that a person controls the number. Ownership verification and SMS or WhatsApp message delivery are separate capabilities. Check the endpoint documentation for the API you select.
How do I replace a Twilio Lookup request?
Check that the target endpoint provides the fields and coverage your application needs, activate the appropriate plan, and send an authenticated HTTP request. URL-encode the international plus sign. Inspect the actual JSON response before mapping it into your application.
Review the API before you build.
Explore the published endpoints, available plans, and usage terms for your application.
