Stop Fighting Rate Limits.
Let Steel Handle It.
steel-api automatically queues, retries, and load-balances your API calls. Integrate once — never worry about rate limits again.
Rate Limits Are Breaking Your Apps
Developers integrating with high-volume APIs face constant friction: unexpected crashes, complex retry boilerplate, and no visibility into traffic distribution.
Rate Limit Errors
APIs like Groq and OpenAI enforce strict rate limits. One burst of traffic and your app crashes with 429 errors.
Fragile Retry Logic
Hand-written retry loops are brittle, hard to test, and rarely handle exponential backoff correctly.
No Load Distribution
Hitting a single endpoint with all traffic creates bottlenecks. Without balancing, one slow response blocks everything.
Everything You Need to Tame API Traffic
Automatic Queuing
When rate limits approach, steel-api queues your requests automatically. No manual throttling, no lost calls — just smooth, ordered processing.
Configurable queue size, priority levels, and FIFO or priority ordering.
Intelligent Retry
Failed requests are retried with exponential backoff and jitter. steel-api respects Retry-After headers and adapts to each API's behavior.
Customizable max attempts, backoff strategy, and per-endpoint rules.
Load Balancing
Distribute traffic across multiple API keys or endpoints. Round-robin, least-connections, or weighted strategies keep your throughput high.
Real-time health checks, automatic failover, and traffic splitting.
Four Steps to Bulletproof API Calls
Install the Package
Add steel-api to your project with a single command.
Configure Your Strategy
Set queue limits, retry rules, and load-balancing strategy.
Replace Your API Calls
Swap direct API calls with steel-api.call() — that's it.
Monitor & Scale
Track throughput, retry rates, and queue depth in real time.
import { SteelAPI } from 'steel-api';
const steel = new SteelAPI({
apiKey: 'sk-your-key',
retry: { maxAttempts: 3 },
queue: { maxSize: 1000 },
balance: { strategy: 'round-robin' }
});
// Rate limits handled automatically
const res = await steel.call(
'https://api.groq.com/v1/chat',
{ model: 'llama-3.3-70b',
messages: [{ role: 'user', content: 'Hello!' }] }
);Why Developers Choose steel-api
Zero Crashes
Automatic queuing and retry means your app stays online even when APIs are under heavy load.
Simpler Codebase
Delete hundreds of lines of retry and throttle logic. One middleware handles it all.
Lower Latency
Smart load balancing routes requests to the fastest available endpoint in real time.
Built to Scale
From prototype to production — steel-api handles 10,000+ requests per minute out of the box.
