Capture caller details
Get a call or message → Notis captures the number, looking up reputation, carrier, business, and complaint history.

Get phone-check digests
Receive scheduled summaries of numbers checked, reputation trends, and your account activity in your messages daily or weekly.

What people automate with
Callerapi + Notis.
Details →Check a number before calling back
Ask your Telegram bot to check an E.164 phone number and get Callerapi reputation and carrier details before you return an unfamiliar call.
Send caller identity to Telegram
When a phone workflow sends caller details to Notis, post a concise identity summary in Telegram for fast follow-up.
Details →Inbound Lead Reputation Check
Automatically verify phone reputation for new leads when they arrive
Details →Check phone numbers shared in Slack
When a channel message includes an E.164 phone number, retrieve its Callerapi information so your team can review the details in the run report.
Details →Check new sales lead numbers
Look up a lead's phone number when its Notion record changes, then summarize caller reputation and carrier details for a quick review.
Track suspicious CallerAPI calls in Linear
Create a Linear issue when a webhook reports a suspicious caller, so spam follow-up lands in your team queue.
