Overview

CARTO is a geospatial platform API that provides location intelligence and data analysis tools for mapping and prediction. You authenticate with an API key to access datasets, create maps, and run spatial SQL queries. It is well-suited for building data-driven location apps and visualizations.

Beginner Tip

Start with the CARTO SQL API to query your uploaded datasets using standard SQL with a simple GET or POST request. Make sure your dataset is set to public or pass your API key correctly.

Available Data

vehicle make and model
year and specifications
fuel economy
VIN decode data
prediction result with confidence score
input name or text

Example Response

JSON Response 
{
  "make": "Toyota",
  "model": "Camry",
  "year": 2025,
  "engine": "2.5L 4-cylinder",
  "fuel_economy": {
    "city_mpg": 28,
    "highway_mpg": 39
  },
  "msrp": 28400
}

Field Reference

rows Array of result objects from the SQL query, one per matching record.
total_rows Total number of rows returned by the query.
time Query execution time in seconds.
fields Metadata describing each field name and its data type.
error List of error messages if the query failed.

Implementation Example

Request 
const url = "https://carto.com/";
// 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);

Common Errors & Troubleshooting

401 Unauthorized API key is missing or incorrect in the request.
✓ Pass your API key as the api_key query parameter or in the Authorization header as documented.
SQL query error The SQL syntax is incorrect or references a table that does not exist.
✓ Test your query in the CARTO dashboard SQL editor first before using it in the API.
429 Too Many Requests You have exceeded the rate limit for your plan.
✓ Add exponential backoff to your requests and consider upgrading your CARTO plan for higher limits.

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
