steel-api automatically queues, retries, and load-balances your API calls. Integrate once — never worry about rate limits again.
Developers integrating with high-volume APIs face constant friction: unexpected crashes, complex retry boilerplate, and no visibility into traffic distribution.
APIs like Groq and OpenAI enforce strict rate limits. One burst of traffic and your app crashes with 429 errors.
Hand-written retry loops are brittle, hard to test, and rarely handle exponential backoff correctly.
Hitting a single endpoint with all traffic creates bottlenecks. Without balancing, one slow response blocks everything.
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.
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.
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.
Add steel-api to your project with a single command.
Set queue limits, retry rules, and load-balancing strategy.
Swap direct API calls with steel-api.call() — that's it.
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!' }] }
);Automatic queuing and retry means your app stays online even when APIs are under heavy load.
Delete hundreds of lines of retry and throttle logic. One middleware handles it all.
Smart load balancing routes requests to the fastest available endpoint in real time.
From prototype to production — steel-api handles 10,000+ requests per minute out of the box.
Join thousands of developers who trust steel-api to handle rate limits, retries, and load balancing — so they can focus on building.
