Calling Code Lookup Skill

What this skill does

Let your agent resolve any country to its international dialing code. Call it as an MCP tool to add +33, +1 and more from a 2-letter ISO code. You switch it on with a single toggle — no SDK and no endpoint wiring — and it answers over MCP or REST using the same key as every other skill.

Ways to use it

Turn IDs into detail

Enable Calling Code Lookup and your app can look up calling code — expand an identifier into full structured detail — in a single call, no integration per source.

A tool your agent reaches for

Over MCP, your model calls callingcode to enrich data mid-workflow exactly when it's needed.

Enrich from your backend

Call Calling Code Lookup over REST to look up calling code across a batch in a server-side job, one key for all of it.

Use it in your app

Once enabled, this skill is reachable two ways — pick whichever fits how you build. Both use the same key.

For AI agentsMCP

It appears to your model as a callable tool. No extra code — the agent invokes it when a task needs it.

callingcode

For apps & backendsREST

Call it from your server with one request and your key. Node, Python, Go — anything that can send a GET.

GET /v1/callingcode

Ask your agent

“Enable Calling Code Lookup and ask your agent to look up calling code.”
“Use the Calling Code Lookup skill for me.”

How to connect it over MCP or REST.

How do I add Calling Code Lookup to my app or agent?

Enable the Calling Code Lookup Skill on VerveKit, then reach it two ways with the same key: over MCP (it appears to your agent as the callingcode tool) or over REST (call it from any backend). No SDK to install and no endpoint to wire.

MCP or REST — which should I use?

Both work off one key. Use MCP when an AI agent should decide when to look up calling code — the skill shows up as a callable tool. Use REST when your own server-side code should call it directly. Many apps use both.

Which agents and frameworks does it work with?

Any MCP client — Claude, Cursor, LangChain, and custom agents all speak the Model Context Protocol, so Calling Code Lookup appears as a standard tool with nothing skill-specific to integrate.

How many credits does a Calling Code Lookup call cost?

Each call costs 1 credit. Every skill rides the same key and the same connection, so enabling more skills doesn't add more integrations to manage.

Do I need to install anything?

No SDK and no endpoint wiring — enabling the skill is a toggle. You point your agent at the VerveKit MCP endpoint (or call REST) and Calling Code Lookup is available immediately.

Where does the data come from, and what shows on my bill?

VerveKit runs on APIVerve, our production data engine; Calling Code Lookup is one of 300+ skills on the same key. Invoices and card statements show APIVERVE.
