Install Jentic One Beta

Connect the Geocodio API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Geocodio 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 | sh

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 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.

Capabilities

What an agent can do with Geocodio API.

Convert a US or Canadian address to latitude and longitude with /geocode

Reverse-geocode coordinates back to a postal address with /reverse

Append congressional district, census block, and school district data on a single request

For Agents

Geocode US and Canadian addresses, reverse-geocode coordinates, and append congressional, census, timezone, and district data - single requests or batch lists.

Use for: I need to geocode '1600 Pennsylvania Ave, Washington DC', Reverse geocode 38.8977, -77.0365 to a US street address, Append the congressional district to 500 customer addresses, Upload a CSV of addresses for batch geocoding

Not supported: Does not handle routing, turn-by-turn directions, or worldwide coverage outside the US and Canada - use for North American geocoding and address-data appends only.

Use Cases

Patterns agents use Geocodio API for, with concrete tasks.

★ Customer Address Cleanup

B2C operations teams onboarding new customers run their address book through Geocodio to standardise, validate, and append latitude/longitude. The /geocode endpoint accepts a free-form address and returns the canonical form along with coordinates, so downstream systems work with consistent formatting and can route shipments accurately.

Send each customer address to /geocode, store the canonical address and coordinates, and flag any record with accuracy below 0.8 for manual review

Political Geography Enrichment

Civic-tech tools and advocacy platforms need to know which congressional district a constituent lives in. Geocodio's append fields return congressional district, state-legislative district, and census block on a single /geocode call, eliminating the need to maintain separate shapefile lookups.

Geocode a list of voter addresses with the cd field appended, then group voters by congressional district for a campaign report

Bulk Spreadsheet Geocoding

Analysts with spreadsheets of thousands of addresses use Geocodio's list endpoints to upload, process, and download an enriched file without writing batch loops themselves. POST /lists uploads the file, GET /lists/{listId} polls status, and GET /lists/{listId}/download returns the result CSV - useful for one-off enrichment without standing up an ETL pipeline.

Upload addresses.csv to /lists, poll /lists/{listId} until processed, then call /lists/{listId}/download for the enriched file

AI Agent Address Resolver

An AI agent answering location questions or assembling a customer file can call Geocodio through Jentic. The agent searches for 'geocode an address', loads the /geocode schema, and executes the call with the address string. The Geocodio API key stays in the vault and the agent gets back a structured location object.

Search Jentic for 'geocode an address', execute /geocode for the address provided in the user prompt, and return the canonical address with lat/lng

Key Endpoints

11 endpoints — geocodio is a us- and canada-focused geocoding api that converts addresses to coordinates and back, with optional data appending for congressional districts, census blocks, school districts, timezones, and more.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your Geocodio API key is stored once, encrypted, by your own Jentic One instance and injected as either the api_key query parameter or the Authorization bearer token at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'geocode an address' or 'append a congressional district', and Jentic returns the matching Geocodio operation with its parameter schema so the agent picks the right endpoint and append fields without browsing the reference docs.

FAQs

Specific to using Geocodio API through Jentic.

What authentication does the Geocodio API use?

Geocodio accepts an API key passed as the api_key query parameter or as a bearer token in the Authorization header. Through Jentic the key is stored encrypted in the vault and attached at execution time, so an agent calling /geocode never handles the raw secret.

Can I geocode Canadian as well as US addresses?

Yes. Geocodio supports both US and Canadian addresses on the same /geocode and /reverse endpoints. Specify country='ca' in the query parameters to bias parsing for Canadian formats.

Can I append congressional districts to my addresses?

Yes. Pass fields=cd (or cd119, cd118 for a specific Congress) on /geocode or /reverse to receive the congressional district alongside the coordinates. The same fields parameter accepts census, school, timezone, and other appends.

What are the rate limits for the Geocodio API?

The OpenAPI spec does not declare a per-second rate limit. Geocodio meters by lookups per day on the paid plans documented at geocod.io - the /lists endpoints are the recommended path for very large jobs because they process server-side rather than counting against streaming quotas.

How do I batch-geocode a CSV of addresses through Jentic?

Run pip install jentic, search Jentic for 'upload addresses for batch geocoding', then call POST /lists with the file, poll GET /lists/{listId} for status, and download via /lists/{listId}/download once the list is processed.

Is the Geocodio API free?

Geocodio offers a free tier with daily lookup allowances and paid plans for higher volume. Pricing tiers and append-field availability are listed on geocod.io - the API surface is the same across tiers but rate and feature limits vary.

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

Yes. Because you run Jentic One yourself, your own rules decide which Geocodio operations and credentials the agent may use. Since the list id sits in the URL path (/lists/{listId}), you can pin the agent to a single list so it only reads and downloads that list's results and nothing else. Broader operations such as creating new lists with POST /lists or running single-address /geocode and /reverse calls stay off limits unless you explicitly grant them.
