No long-term commitment. Upgrade, downgrade, or cancel anytime. Free Trial includes up to 50 requests.
Check whether a URL can be indexed by Google: meta robots, X-Robots-Tag, canonical and robots.txt signals in one call, returned as a graded JSON report.
HTTP status and redirects, X-Robots-Tag directives, meta robots and meta googlebot tags, rel=canonical from the HTML head and the Link header, and the robots.txt decision for the URL using Google's matching rules (longest match wins, Allow wins ties, wildcards and the end anchor).
Indexable is true when no blocking signal was found, false when a noindex, robots.txt block, error status or expired unavailable_after was found, and null when the result cannot be determined, for example when the server answers 403 or robots.txt is unreachable.
No. It checks the signals the page and its server declare. It does not query Google's index, does not render JavaScript and does not detect soft 404 pages, so a clean report is not a guarantee that Google will index the page.
Use the optional userAgent parameter with googlebot (default), bingbot or any to choose which robots.txt group and bot-specific directives are applied. Results are cached for 15 minutes; add fresh=1 to bypass the cache.
Yes. A value without a scheme such as example.com is treated as https. The API follows up to 5 redirects, reads the first 1 MB of the page, times out after 10 seconds and refuses private network addresses.
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.
