Overview

The SuperHero API aggregates data on thousands of superheroes and villains from Marvel, DC, and other universes in a single REST API. You can look up power stats, biography, appearance, and images for any character using their numeric ID. An API key is required but free to obtain at superheroapi.com.

💡

Beginner Tip

Get your free API key at superheroapi.com/api.html, then fetch any hero by ID using /api/YOUR_API_KEY/{id}. Character IDs range from 1 to 731 — start with a few to explore the data structure.

Common Errors & Troubleshooting

"error": "invalid id" Requested character ID is outside the valid range of 1 to 731
✓ Stay within IDs 1-731 or use the search endpoint by name to find valid character IDs
"error": "invalid access token" API key is missing or incorrect in the URL path
✓ Double-check your API key from the superheroapi.com dashboard and place it correctly in the URL path
null values in powerstats Some characters have incomplete data in the dataset
✓ Always treat powerstats fields as potentially null and provide fallback display values in your UI
