One Endpoint, Every Icon
Authenticate with your API key, then request icons by name, slug, or collection ID. Responses include optimized SVG, metadata, and variant options — all in a single call.
Base URL: https://api.iconflow.dev/v2 | Auth: Bearer token in Authorization header | Rate limit: 600 req/min on Pro plan
// Fetch a single icon by slug
const response = await fetch(
'https://api.iconflow.dev/v2/icons/arrow-north-east',
{
headers: { 'Authorization': `Bearer ${ICONFLOW_API_KEY}` },
}
);
const icon = await response.json();
// → { slug: "arrow-north-east", svg: "<svg>...", width: 24, height: 24, collection: "essential" }// Search icons across all collections
const results = await fetch(
'https://api.iconflow.dev/v2/search?q=settings&limit=12&style=outline',
{
headers: { 'Authorization': `Bearer ${ICONFLOW_API_KEY}` },
}
);
const { icons, total } = await results.json();
// → { icons: [...], total: 47 }// Retrieve an entire collection (e.g., "essential" pack)
const collection = await fetch(
'https://api.iconflow.dev/v2/collections/essential?format=zip',
{
headers: { 'Authorization': `Bearer ${ICONFLOW_API_KEY}` },
}
);
// → 248 icons, ~1.2 MB gzipped, ready for build-step bundlingTip: Use the Accept: application/json header for metadata-only responses (no SVG payload) when building icon pickers or design systems. Cuts bandwidth by ~85%.
Supported SDKs
Official client libraries handle auth, caching, and pagination out of the box.
JavaScript / TypeScript
@iconflow/sdk — npm package with ESM, CommonJS, and Deno support. Tree-shakeable icon imports.
React & Next.js
@iconflow/react — <Icon /> component with lazy loading, SSR-safe rendering, and automatic deduplication.
Swift & Kotlin
IconFlowKit — native iOS and Android libraries. Integrates with SwiftUI and Jetpack Compose icon systems.
Real-World Applications
Built for How Teams Ship
From SaaS dashboards to mobile apps, the IconFlow API powers icon delivery at every layer of the stack.
Design System Tokenization
Generate icon sprite sheets and CSS custom properties at build time. Teams at Ramp and Plaid use IconFlow's bulk export endpoint to bake 200+ icons into their design tokens, keeping iconography consistent across 14 product surfaces.
Mobile App Iconography
Preload icon bundles for offline use. The Swift and Kotlin SDKs cache icon sets locally, so your React Native or Flutter app renders icons instantly — even on airplane mode. Used by 340+ mobile teams on the Pro plan.
Dynamic Icon Pickers
Power a searchable icon library inside your CMS or no-code builder. The search endpoint supports fuzzy matching, style filtering (outline, filled, duotone), and collection scoping — perfect for Wix, Webflow, or Framer plugin integrations.
Performance Monitoring
Track icon load times and bundle impact with the X-IconFlow-Metrics response header. Shipper and Vercel teams use this to set Lighthouse budgets — keeping icon payloads under 12 KB per page load, consistently.
