5 Best Stock Image and Video Footage APIs
1 – Creative Suite API by Depositphotos and VistaCreate
Topping the list is the best image and video API—the Creative Suite API by Depositphotos and VistaCreate. It's an ideal API for creative companies.
It features a massive stock content library with millions of high-quality and diverse photos, illustrations, vectors, videos, and music files and an intuitive design editor with advanced editing tools and features.
What sets this image and design API apart is its unmatched creative freedom, allowing you to choose and pay for only the tools and features you want to use. Additionally, you can rebrand some features or the entire business solution using your company logo and colours.
Regarding image copyrights, Depositphotos offers worry-free licensing and commercial safety. All visuals on the platform are royalty-free, and most don't require attribution, making it easy for businesses to use them without legal concerns.

2 – Vecteezy API
A staggering 67% of companies that currently neglect graphic design would embrace it if there were a faster, more cost-effective solution for producing graphic design materials.
Stock media APIs provide businesses the resources to create various designs without switching between multiple platforms or investing in expensive software.
Vecteezy API, for example, is an excellent solution for graphic designers, as it features an extensive library of SVGs and PNGs. These files are often used for creating logos, posters, infographics, email marketing templates, packaging, web design, and more.
Vecteezy also claims that setting up their REST API is a breeze, making it accessible to novice and experienced developers at large tech corporations. And when it comes to licensing, you don't have to worry about attribution or royalties if you use Vecteezy's paid plan.
Key features:
- Extensive content library with millions of vectors, photos, images, and videos;
- AI-powered search capabilities;
- Worry-free licensing.
3 – Unsplash API
Gartner reports that in 2024, average marketing budgets fell to a post-pandemic low, decreasing by 7.7% compared to the previous year. As a result, many businesses are looking for cost-effective solutions to support their marketing efforts.
The Unsplash API is a popular API among companies looking to cut costs while still accessing high-quality images. This API is available for free. Nevertheless, it is accompanied by rules and guidelines that must be followed.
The platform offers seven million photos and illustrations, simple integration, and unlimited API requests. However, your application will initially operate in demo mode, with limited API calls. When you are ready, you can move to production mode.
Key features:
- Simple integration;
- Free use of the API with attribution required;
- Official libraries and SDKs in PHP, Ruby, Javascript, iOS, and Android.
4 – Pexels API
Like the Unsplash API, the Pexels API offers stock photos and videos for free. The platform requires attribution to both Pexels and its contributors in exchange for free content. Additionally, Pexels users must manually check for potential copyright violations.
Everything on the website is hand-picked, which is why Pexels offers a limited selection of files. However, you can be confident in the quality of the three million images on the platform.
The limited file selection allows Pexels only to upload authentic visuals. As such, the Pexels API has the potential to be used in a variety of creative projects, from websites and mobile apps to marketing materials and design tools.
Key features:
- Easy integration;
- No licensing fees are required;
- Only hand-selected content.
5 – Pixabay API
The Pixabay API is another free API that provides access to over five million images and videos. But, as is often the case with free stock marketplaces, they share images between platforms. Therefore, the content you find on Pixabay, Pexels, and Unsplash is not unique to each platform.
This API suits startups and small businesses that want to save money on quality visual content for their projects. The only problem is that each image requires a manual check for copyright and licensing restrictions.
This means you must ensure that the content depicted, including people, logos, drawings, etc., can be used without restrictions.
Key features:
- Free of charge;
- An unlimited number of API requests.
Wrapping up
We've seen a clear trend in recent years: marketing budgets are shrinking, and digital platforms call for more engaging visuals.
The only way to keep up with this trend is to use image APIs.
They provide businesses instant access to high-quality visuals through stock media libraries, offering faster and more efficient content creation.
Best Image APIs to Use: FAQs
What factors should I consider when choosing an image API for my business?
Look for APIs with 99.9%+ uptime, transparent pricing that scales with your growth, complete documentation, and active developer support. The most overlooked factor? Speed. Image processing that takes even 200ms too long can cost you thousands in lost conversions. Test multiple APIs side-by-side before committing.
Which image API offers the best value for small businesses with limited budgets?
Cloudinary's free tier is unmatched for bootstrapped startups – 25GB storage and 25GB monthly bandwidth without spending a dime. But here's the real value: their transformation capabilities let you generate unlimited variations from a single image asset, multiplying your creative output without additional storage costs.
How vital is CDN integration when selecting an image API?
Non-negotiable. A global CDN can slash your image load times by 60-80%. Without it, you're bleeding customers with every second of load time. ImageKit and Cloudinary offer built-in CDNs that automatically serve images from the edge location closest to your users, giving you instant global reach without additional infrastructure.
What image optimisation capabilities should I look for in an API?
Demand automatic format conversion (WebP, AVIF), responsive sizing, and intelligent compression. The difference between basic and advanced optimisation can be 70% smaller file sizes while maintaining visual quality—look for APIs with content-aware cropping that preserves the essential parts of your images regardless of display size.
Which image API handles high-volume processing best?
Imgix and Cloudflare Images are built for scale. When you're processing millions of images daily, their infrastructure won't flinch. But remember – raw performance isn't everything. Look for APIs with intelligent caching and transformation pipelines that minimise redundant processing. This can cut your costs by 30-50% at scale.
How do I evaluate the security features of an image API?
Demand signed URLs, access controls, and the ability to strip metadata. Image APIs can be vectors for data breaches – I've seen companies leak location data through unstripped EXIF metadata. Also, check if the API offers optional watermarking and obfuscation to protect your visual assets from unauthorised use.
Which image API has the most advanced AI capabilities?
Cloudinary's AI capabilities are currently unmatched – automatic background removal, object recognition, and intelligent cropping that identifies and preserves the most critical parts of your images. These features can automate what would otherwise require a full-time designer, saving you $5,000-$7,000 monthly in production costs.
What should I know about pricing models for image APIs?
Avoid APIs with unpredictable pricing based on transformations or API calls. The best APIs charge based on storage and bandwidth – metrics you can forecast. Some APIs advertise low rates but charge per transformation, which explodes costs when you scale. Do the math on your expected usage before committing.
How important is it to have video processing capabilities alongside image API features?
It's critical if you're planning any video content in the next 18 months. Switching providers later will cost you 5- 10 times more in migration and development time. ImageKit and Cloudinary offer unified APIs for images and videos, letting you apply the same optimisation and transformation logic across all visual content.
Which image APIs offer the best developer experience?
Cloudinary and Imgix consistently rank highest for developer satisfaction. Their SDKs are available for all major languages and frameworks, cutting implementation time by 60-70%. But don't overlook the importance of thorough documentation and responsive support – these can save you weeks of debugging when issues arise.
How should I approach testing different image APIs before deciding?
Set up a comparative test with your actual content. Create identical transformations across 3-5 providers and measure rendering quality and load times. Then, a stress test will be performed with batch uploads and concurrent transformations. The performance difference between APIs often only becomes apparent under load – when it's too late to switch quickly.
