Groq
Fast AI inference API with free tier, supports Llama, Mixtral, Gemma models
Verified today: 100% uptime
Is Groq free, and does it need an API key?
Free plan with rate limits set per model. The paid Developer plan raises them and adds batch processing.
- Price
- Free tier, paid above it
- API key
- Required, free signup
- Free limits
- Varies by model. For example, GPT-OSS and Qwen models allow 30 requests a minute, 1,000 a day and 8,000 tokens a minute on the free plan.
How to get a Groq API key
- Sign in to the Groq console.
- Create a key under API Keys.
- Send it as a Bearer token. The API is OpenAI-compatible.

Overview & Architectural Role
Groq provides programmatic access to fast ai inference api with free tier, supports llama, mixtral, gemma models. Delivered over secure HTTPS protocols, it exposes structured endpoints designed to integrate cleanly into modern frontend frameworks, backend microservices, and automated data pipelines without requiring local database provisioning.
Who it is built for
Engineers building web dashboards, mobile applications, CLI utilities, or background cron workers in need of reliable ai data feeds.
Architectural Advantage
Consuming Groq removes the operational overhead of running custom scrapers, orchestrating headless browser fleets, or manually seeding and maintaining a local database. Instead of reverse-engineering volatile DOM layouts or dealing with anti-bot IP blocks, your application connects directly to a standardized JSON interface designed for backend ingestion with consistent schema schemas. Dedicated authentication ensures rate quotas and credential tracking per project environment.

Core Use Cases & Architecture Ideas
Practical real-world patterns for integrating Groq into software systems.
Automated Content Enrichment Pipeline
Augment user submissions or catalog items with metadata, tagging, summaries, or vector analysis.
Architecture: An async job queue pushes inbound text or media to Groq, awaiting the transformed payload before updating the primary relational database.
Interactive Chat & Intelligent Assistant
Power real-time conversational flows, prompt engineering experiments, or automated customer support triage.
Architecture: Next.js API route streams response tokens from Groq directly to a React frontend using Server-Sent Events (SSE).
Sentiment & Anomaly Detection Monitor
Classify incoming customer feedback, support tickets, or error logs to detect customer sentiment trends.
Architecture: Ingestion webhook forwards message payloads to Groq for classification, routing high-priority flags to Slack notification channels.
Code Implementation Examples
Production-ready starting templates with error handling for Groq.
// Requires an API key. Check the docs for whether it goes in a header or a query parameter.
// Modern native fetch with error handling
async function callApi() {
try {
const response = await fetch('https://console.groq.com/api/v1/resource', {
method: 'GET',
headers: {
'Authorization': 'Bearer YOUR_API_KEY',
Accept: 'application/json',
},
});
if (!response.ok) {
throw new Error(`HTTP ${response.status}: ${response.statusText}`);
}
const data = await response.json();
console.log('Response payload:', data);
return data;
} catch (error) {
console.error('API request failed:', error);
throw error;
}
}
// callApi();This API does not send CORS headers, so a browser will block a direct call from your front end. Call it from your server, or put a small proxy in front of it.
Response Payload & Live Testing

Expected JSON Response Payload

}
],
"usage": {
"prompt_tokens": 18,
"completion_tokens": 12,
"total_tokens": 30
}
}Format: application/json
Integration Considerations & Best Practices
Technical factors to keep in mind when integrating Groq into production environments.
Implement In-Memory or Edge Caching
Avoid triggering rate limits on public feeds by caching response payloads in Redis, Vercel KV, or standard HTTP Cache-Control headers with a 5-to-15 minute TTL.
Shield Credentials in Backend Route Handlers
Never expose private API keys in client-side JavaScript or bundle environments. Proxy requests through a Next.js API route or serverless backend to keep secret keys out of public DevTools inspection.
CORS Proxy Required for Browser Frontend Calls
This API does not send Access-Control-Allow-Origin response headers. Direct fetch() calls from browser JavaScript will fail due to Same-Origin Policy. Route your calls through a server backend or lightweight edge proxy.
Validate HTTP Status Before Parsing JSON
Always inspect response.ok before executing response.json(). Upstream services returning 4xx or 502 Bad Gateway often serve HTML error pages, which cause syntax errors when parsed as JSON.

Groq — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is the Groq API free?
Free plan with rate limits set per model. The paid Developer plan raises them and adds batch processing. Checked on 2026-10-24.
Does Groq need an API key?
Yes, and it is free: you get one by signing up. Send it as Authorization: Bearer YOUR_KEY.
How do I get a Groq API key?
1. Sign in to the Groq console. 2. Create a key under API Keys. 3. Send it as a Bearer token. The API is OpenAI-compatible.
What are the Groq API rate limits?
Varies by model. For example, GPT-OSS and Qwen models allow 30 requests a minute, 1,000 a day and 8,000 tokens a minute on the free plan.
Can I call Groq from browser JavaScript?
Not directly. Groq did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.
Is Groq still working?
Yes, as of 2026-10-24. Our automated check reached Groq and recorded a 100% reliability score with a median response time of 338 ms. We re-check on a schedule, and this page updates with the result.
