Hardiness Zone Skill

What this skill does

Let your agent look up USDA plant hardiness zones. Call it as an MCP tool to turn any US ZIP code into its zone and temperature range. 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

Location smarts in one toggle

Enable Hardiness Zone and your app can add hardiness zone to your app — geocode, resolve timezones, measure distance — without integrating a maps provider or managing another key.

A tool agents call to place things

Over MCP, hardinesszone becomes the tool your model reaches for whenever it needs to ground reasoning in a real location.

Compose with your logic

Call Hardiness Zone from your backend and feed its structured output straight into the code you already have.

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.

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/hardinesszone

Ask your agent

“Enable Hardiness Zone and ask your agent to add hardiness zone to your app.”
“Where is this location and what timezone is it in?”

How to connect it over MCP or REST.

How do I add Hardiness Zone to my app or agent?

Enable the Hardiness Zone Skill on VerveKit, then reach it two ways with the same key: over MCP (it appears to your agent as the hardinesszone 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 add hardiness zone to your app — 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 Hardiness Zone appears as a standard tool with nothing skill-specific to integrate.

How many credits does a Hardiness Zone 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 Hardiness Zone is available immediately.

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

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