Springbolt X is a powerful lead intelligence API that helps businesses identify and enrich anonymous visitors, resolve contact data from LinkedIn profiles, and generate targeted lead lists from keywords.
The API supports keyword to lead generation, lead enrichment from LinkedIn URLs, website visitor deanonymization, phone number retrieval, IP to company resolution, and email hashing.
All endpoints require Bearer token authentication. Built for sales teams, growth hackers, and data driven marketers.

Each endpoint returns structured data relevant to lead generation and enrichment. For example, the IP to Company endpoint returns company details like name, domain, and employee count, while the Deanonymization endpoint provides personal information such as name, email, and job title.
Key fields vary by endpoint. For instance, the List Building endpoint includes resolution ID, status, and callback URL, while the API Enrichment endpoint returns first name, last name, and work email, among others.
Parameters include keywords, date ranges, callback URLs, and specific identifiers like IP addresses or LinkedIn URLs. Users can customize requests by specifying these parameters to tailor the data returned to their needs.
Response data is organized in JSON format, typically containing a success flag, message, and a payload with relevant details. For example, the Count Result endpoint includes a count of hashed emails and input parameters used for the request.
Data is sourced from various online platforms, including LinkedIn and IP databases. The API aggregates and enriches this data to provide comprehensive lead information, ensuring a broad coverage of potential leads.
Typical use cases include identifying potential leads from website visitors, enriching existing contact data, and generating targeted marketing lists based on keyword searches. Sales teams and marketers can leverage this data for more effective outreach.
Users can utilize returned data by integrating it into their CRM systems for lead tracking, using enriched contact details for personalized outreach, or analyzing keyword trends to refine marketing strategies.
Data accuracy is maintained through regular updates and validation checks against multiple sources. The API employs quality control measures to ensure that the information provided is reliable and up-to-date.
To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used 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.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
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, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
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.
