Overview
The Noun Project API gives access to a vast library of over 3 million community-created icons covering virtually every concept imaginable. It uses OAuth 1.0a for authentication, which is more involved than API key auth but gives you access to both free and licensed icon downloads. Icon designers and app developers use it to find icons that match specific semantic meanings.
Beginner Tip
OAuth 1.0a requires signing each request with your key and secret — use a library like oauth-1.0a for Node.js or requests_oauthlib for Python rather than crafting signatures manually.
