After signing up, every developer is assigned a personal API access key, a unique combination of letters and digits provided to access to our API endpoint. To authenticate with the PhoneCheck API simply include your bearer token in the Authorization header.
| Header | Description |
|---|---|
Authorization
|
Required
Should be Bearer access_key. See "Your API Access Key" above when you are subscribed.

No long-term commitment. Upgrade, downgrade, or cancel anytime.
Phone number validation API for 240+ countries: numbering-plan validity, country, E.164 and display formats, line type where plan data supports it. Batch up to 100.
Up to 100, and a batch counts as one API call. Sending more than 100 returns a 400 BATCH_TOO_LARGE error naming the limit and how many you sent — split the list and retry.
Because the numbering-plan metadata for that market does not separate line types. Mainland China, France, Germany, Brazil and India numbers commonly return UNKNOWN; US, GB and AU numbers carry reliable type data. Validity, country and formatting are unaffected.
No. It means the number is correctly formed under its country's numbering plan. PhoneCheck does numbering-plan parsing only — no carrier lookup, no reachability check.
245 countries. GET /countries lists every supported country with its calling code.
Yes. Parsing is done locally with libphonenumber — the same numbering-plan data behind Android — so a number returns exactly the same verdict from the single endpoint and inside a batch.
To obtain your API key, first sign in to your account and navigate to the API you want to use. From the API's Pricing section, choose a plan and complete the subscription process. Once subscribed, return to the API page and you will see your API Access Key displayed at the top of the documentation page. You can use this key to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
The free trial lasts for 7 days and allows you to make up to 50 API requests.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes. If the API offers a free trial, you will see a "Free 7-Day Trial" option in its Pricing section. The trial lasts for 7 days and allows up to 50 API requests, enabling you to evaluate the API before subscribing to a paid plan.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
You can monitor your API usage through the response headers included with every request:
x-zyla-api-calls-monthly-used: Shows the total number of API requests you have used during the current billing period.
x-zyla-api-calls-monthly-remaining: Shows the number of API requests you have remaining for the current billing period.
Yes, you can cancel your subscription at any time. Simply go to the Pricing section of the API you're subscribed to and click the "Unsubscribe" button.
Please note that upgrades, downgrades, and cancellations take effect immediately. Once your subscription is canceled, access to the service will end immediately, regardless of any remaining API calls in your quota.
