Connect Claude & ChatGPT to CallerAPI

Ask your AI whether a phone number is spam, who the carrier is, or when the number was last ported, and get the answer from CallerAPI. It can check which online services a number is registered with, read daily spam reports for a country, score a call transcript or recording for scams and look up the reputation of STIR/SHAKEN call signers.

Questions

What can the AI do in CallerAPI?

The AI can look up phone numbers for spam score, caller ID and carrier, add a live network (HLR) check, and get the porting date, porting history and online presence of a number. It can read daily spam reports by country, score a call transcript or audio for scams, read voice screening sessions and verdict categories, and check STIR/SHAKEN signer reputation. It can also show your remaining credit balance.

Does the AI see my CallerAPI credentials?

No. Your CallerAPI API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on. Number lookups, porting and online presence checks use CallerAPI credits, so you can switch off the ones you do not need or require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own CallerAPI account, and lookups use credits from your CallerAPI plan.

How do I keep an eye on credits?

Ask the AI for your account details. It reads your CallerAPI account and shows the remaining credit balance. Number lookups, porting and online presence checks use credits, so checking the balance before a larger batch is a good habit.
