Not supported: Does not handle payments, communications, or crm — use for developer tools only.
The Smarty US ZipCode API provides detailed information about US ZIP codes including city, state, latitude, longitude, and more. It validates ZIP codes and returns associated metadata including alternate city names, county information, and timezone data. The API exposes 2 endpoints secured with apiKey authentication.
Install Jentic One Beta
Connect the Smarty US ZipCode API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Smarty US ZipCode API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

AI Agent Integration via Jentic
AI agents discover and call Smarty US ZipCode API endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle apiKey tokens manually.
Search Jentic for 'batch zip code lookup', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Smarty US ZipCode API apiKey credentials are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens — raw secrets never enter the agent context.
Intent-based discovery
Agents search by intent (e.g., 'batch zip code lookup') and Jentic returns the matching Smarty US ZipCode API operation with its input schema, so the agent can call the right endpoint without browsing docs.
Time to first call
Direct Smarty US ZipCode API integration: 1-3 days for auth handling, response parsing, and error cases. Through Jentic: under 1 hour — search, load schema, execute.

FAQs
Specific to using Smarty US ZipCode API through Jentic.
What authentication does the Smarty US ZipCode API use?
The Smarty US ZipCode API uses an API key passed in the `auth-id` query. Through Jentic, these credentials are stored encrypted in the MAXsystem vault and injected at execution time, so raw secrets never enter the agent context.
Can I batch zip code lookup with the Smarty US ZipCode API?
Yes. Use the POST /lookup endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Smarty US ZipCode API?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I batch zip code lookup through Jentic?
Install the Jentic SDK with pip install jentic, authenticate at https://app.jentic.com/sign-up, then search for 'batch zip code lookup'. Jentic returns the matching Smarty US ZipCode API operation with its input schema. Load the schema and execute the call — credentials are injected automatically.
How many endpoints does the Smarty US ZipCode API have?
The Smarty US ZipCode API exposes 2 endpoints covering zipcode lookup operations.
