Frequently asked questions

Ceven does not provide the credits itself but connects to your existing CallerAPI account. The agent can be configured to monitor your credit balance using the user info tool. If your credits fall below a certain threshold, the agent can send a notification to your Slack or email so you can top up your account. This prevents your identity workflows from breaking silently during high volume periods. Since each lookup consumes credits, we recommend setting up a budget alert within the Ceven dashboard to track exactly how many requests your automated workflows are making per day.
CallerAPI requires numbers to be in e.164 format, which means they must include the plus sign and the country code without any spaces, dashes, or parentheses. For example, a US number must look like +12125550123. If your source data contains formatted numbers, Ceven uses a pre processing step to strip out non numeric characters and prepend the correct country code before calling the API. This ensures that you do not waste credits on failed requests due to formatting errors and that the reputation lookup returns the most accurate data possible for that specific region.
Ceven acts as the intelligence layer that makes the decision based on CallerAPI data. While Ceven cannot physically disconnect a phone line, it can trigger a webhook to your telephony provider like Twilio or RingCentral to block a number. For instance, if CallerAPI returns a high risk score or a high number of FTC complaints, the agent immediately sends a command to your phone system to blacklist that number for thirty days. This creates an automated security perimeter where the identity data from CallerAPI drives the actual enforcement on your voice hardware or software.
Rate limits are determined by your specific CallerAPI subscription tier rather than Ceven. Some entry level tiers have strict requests per second limits that can cause 429 errors during massive bursts of calls. To handle this, Ceven implements an intelligent queuing system that spaces out requests to match your tier limits. If the agent detects a rate limit error, it will automatically retry the request using an exponential backoff strategy. This ensures that your identity checks eventually complete without crashing the workflow, though it may add a few seconds of latency during extreme peaks.
CallerAPI uses a hybrid approach. While it maintains a massive database of known spam and business identities, it can also perform real time HLR lookups to see if a number is currently active. When you set the HLR flag to true in a Ceven workflow, the agent is requesting a live check against the carrier network. This is more accurate for verifying if a number is still in service but may take slightly longer to return a result than a standard database query. Most users use the standard lookup for speed and the HLR lookup for high stakes verification.
Branded caller ID depends on the carrier and the region. Not every phone carrier supports the display of business names for all incoming calls. CallerAPI provides the data required to request branding, but the final display on the end user device is subject to carrier rules and the device operating system. Ceven helps you manage this by flagging which numbers have successful branding data and which do not, allowing you to adjust your outreach strategy for numbers that are more likely to be flagged as spam by certain carriers.
When a number is queried, CallerAPI checks its index of reported numbers and official FTC data. Ceven can be told to treat any number with more than zero FTC complaints as a high risk lead. This is particularly useful for security teams who want to proactively flag numbers before they ever reach a human. The agent can pull the specific count of complaints and include that number in the notification sent to the agent, giving the human operator a clear warning about the risk level of the caller before they answer.
CallerAPI is designed for business identity and fraud prevention, not for private surveillance. While it can provide carrier and reputation data for most numbers, it will not provide the personal name of a private individual if that information is not publicly available or part of a business registration. If a number is strictly private, the agent will return the carrier and the risk score but the business name field will remain empty. This ensures compliance with privacy laws while still providing the security data needed to stop robocalls.
