Install Jentic One Beta

Connect the ZipCodeAPI to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the ZipCodeAPI, 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://jentic.com/install.sh?src=apis&api=%2Fapis%2Fzipcodeapi.com%2Fzipcodeapi" | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fzipcodeapi.com%2Fzipcodeapi" | sh
jentic register       # connects your agent to your Jentic One instance

Jentic 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.

★ Maps and Geolocation Operations

Use the ZipCodeAPI to perform maps geolocation operations programmatically. The API provides 10 endpoints covering core functionality including distance between two zip codes, distances from one zip code to multiple others, zip codes within a radius.

Call GET /distance.{format}/{zip_code1}/{zip_code2}/{units} to distance between two zip codes

Automated Distance Management

Automate distance operations by combining multiple ZipCodeAPI endpoints. Agents can distances from one zip code to multiple others and then zip codes within a radius in a single workflow.

Call GET /multi-distance.{format}/{zip_code}/{other_zip_codes}/{units} to distances from one zip code to multiple others, then verify the result

AI Agent Integration via Jentic

AI agents discover and call ZipCodeAPI 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 'distance between two zip codes', load the operation schema, and execute with Jentic-managed credentials

Key Endpoints

10 endpoints — zipcodeapi provides us zip code distance calculations, radius searches, zip-to-location lookups, city-to-zip lookups, and canadian postal code operations.

Why Jentic?

What agents get from Jentic-routed access to this vendor.

Setup

Wiring ZipCodeAPI by hand means embedding your api_key directly in the URL path and templating format and units segments into every request yourself. Through Jentic you install once, import ZipCodeAPI from the API Directory, store the API key once, and your agent calls it.

Permission scoping

ZipCodeAPI takes zip codes as lookup inputs rather than resources you own, so scoping is operations-only: limit the agent to the operations it needs, such as distance and radius lookups. You choose the operations it may call, so nothing beyond the lookups you select runs unless you add it.

Credential isolation

Your ZipCodeAPI key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'distance between two zip codes' or 'zip codes within a radius', and Jentic returns the matching ZipCodeAPI operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using ZipCodeAPI API through Jentic.

What authentication does the ZipCodeAPI use?

The ZipCodeAPI uses an API key passed in the `api_key` path. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.

Can I distance between two zip codes with the ZipCodeAPI?

Yes. Use the GET /distance.{format}/{zip_code1}/{zip_code2}/{units} endpoint. The API returns structured JSON responses that agents can parse and act on directly.

What are the rate limits for the ZipCodeAPI?

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 distance between two zip codes through Jentic?

Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'distance between two zip codes'. Jentic returns the matching ZipCodeAPI operation with its input schema. Load the schema and execute the call - credentials are injected automatically.

How many endpoints does the ZipCodeAPI have?

The ZipCodeAPI exposes 10 endpoints covering distance, radius, location operations.

Can I limit what my agent is allowed to do with the ZipCodeAPI?

Yes. Because Jentic One is self-hosted by you, your own rules decide which ZipCodeAPI operations and credentials the agent may use. ZipCodeAPI takes ZIP codes as lookup inputs rather than resources you own, so scoping is operations-only: you allow just the operations the agent needs, such as distance and radius lookups, and leave out the rest. Nothing beyond the ZIP-to-location or distance lookups you select runs unless you add it.
