Frequently Asked Questions
Everything you need to know about our capabilities verification platform.
How are lookup credits charged?
Credits are only consumed when a check successfully returns a definitive carrier status: RCS_CAPABLE, RCS_NOT_CAPABLE, or UNKNOWN. We do not charge credits for connection timeouts or invalid phone number formats.
Do you offer real-time capability checks?
Yes. Our failover capability managers query carrier databases in real-time through Google RBM and Telnyx adapters, returning verified routing flags.
What is the difference between RCS Capable and device online?
An RCS Capable status means that the mobile number has registered RCS capabilities enabled at the carrier network level. It does not guarantee that the physical device is currently online, powered on, or reachable in real-time.
Can I integrate checking programmatically?
Absolutely. You can generate secure hashed API keys in the developer section of your dashboard and execute checks using standard POST json payloads.
