Overview
Geocod.io is a US and Canada focused geocoding API that converts addresses to coordinates and vice versa, with support for bulk geocoding of thousands of addresses at once. It is known for its accuracy with North American addresses and offers 2,500 free lookups per day. An API key is required and available for free.
Beginner Tip
For single address lookups use the /geocode endpoint; for processing lists of addresses use the /lists endpoint which handles CSV uploads. The free tier resets daily at midnight EST.
Available Data
The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.
Example Response
Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.
{
"status": "success",
"data": {
"result": "Data from Geocod.io",
"description": "Address geocoding / reverse geocoding in bulk",
"timestamp": "2025-01-15T10:00:00Z"

} Field Reference
input Echo of the input address as parsed by Geocod.io into address components. results Array of geocoding results ordered by accuracy, with the best match first. location.lat Latitude of the geocoded address in decimal degrees. location.lng Longitude of the geocoded address in decimal degrees. accuracy Accuracy score from 0 to 1; values above 0.8 indicate a reliable match. accuracy_type Description of the match precision level such as "rooftop", "range_interpolation", or "place". Implementation Example
Calls a real endpoint of this API. Replace any placeholder credentials with your own key.
const url = "https://api.geocod.io/v1.7/geocode?q=1109+N+Highland+St,+Arlington+VA&api_key=YOUR_API_KEY";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
headers: {
"X-API-Key": "YOUR_API_KEY"
}
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?
