Supportivekoala API

Development / API Key Intermediate HTTPS CORS
Varies by plan (check documentation)

Overview

Supportivekoala is an API that auto-generates custom images by filling in templates with dynamic text or data, returning a ready-to-use image URL. It is useful for creating social share cards, personalized banners, email headers, and certificate images programmatically. An API key is required and a free tier is available for getting started.

Beginner Tip

First create a template in the Supportivekoala dashboard, note its template ID, then POST your variable values to the API to get back a rendered image URL you can embed anywhere.

Available Data

randomly generated data
customizable output format
vehicle make and model
year and specifications
fuel economy
VIN decode data

Example Response

JSON Response
{
  "make": "Toyota",
  "model": "Camry",

  "engine": "2.5L 4-cylinder",
  "fuel_economy": {
    "city_mpg": 28,
    "highway_mpg": 39
  },
  "msrp": 28400
}

Field Reference

id Unique identifier for the generated image
url Public URL of the generated image ready to embed or download
template_id The template ID used to generate this image
created_at ISO 8601 timestamp of when the image was generated

Implementation Example

Request
const url = "https://developers.supportivekoala.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 Missing or incorrect API key in the request header
Pass your API key in the x-api-key header; find it in your Supportivekoala account settings
422 Unprocessable Entity Template ID does not exist or required template parameters are missing
Check your template ID in the dashboard and ensure all required variable names in the template are included in the params object
Slow image generation First render of a template can be slower as assets are loaded
Subsequent renders of the same template are faster due to caching; consider pre-warming templates in non-time-sensitive workflows

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.
