Quickstart — Free LLM API
Step 1 — Get your free API key
# Sign up at bazaarlink.ai → /keys → Create Key
# Or register programmatically (for AI agents):
curl -X POST https://bazaarlink.ai/api/v1/agents/register \
-H "Content-Type: application/json" \
-d '{"name": "MyAgent"}'
# Or register programmatically (for AI agents):
curl -X POST https://bazaarlink.ai/api/v1/agents/register \
-H "Content-Type: application/json" \
-d '{"name": "MyAgent"}'
Step 2 — Call the free LLM API (Python)
from openai import OpenAI
client = OpenAI(
base_url="https://bazaarlink.ai/api/v1",
api_key="sk-bl-YOUR_FREE_KEY",
)
# auto:free → zero-cost inference, free model selected automatically
response = client.chat.completions.create(
model="auto:free",
messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)
client = OpenAI(
base_url="https://bazaarlink.ai/api/v1",
api_key="sk-bl-YOUR_FREE_KEY",
)
# auto:free → zero-cost inference, free model selected automatically
response = client.chat.completions.create(
model="auto:free",
messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)
Step 2 — Call the free LLM API (TypeScript / Node.js)
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://bazaarlink.ai/api/v1",
apiKey: "sk-bl-YOUR_FREE_KEY",
});
// auto:free → zero-cost inference
const response = await client.chat.completions.create({
model: "auto:free",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(response.choices[0].message.content);
const client = new OpenAI({
baseURL: "https://bazaarlink.ai/api/v1",
apiKey: "sk-bl-YOUR_FREE_KEY",
});
// auto:free → zero-cost inference
const response = await client.chat.completions.create({
model: "auto:free",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(response.choices[0].message.content);

Free AI API — FAQ
Is the free AI API key really free?
Yes. Sign up, create a key, and call free models at zero cost — no credit card required. 1 models currently include a free quota.
Do I need a credit card to get an API key?
No. Registration requires no payment method. You only add credit if you want to use paid models or go past the free quota.
What are the free tier rate limits?
By default 10 requests per minute and 150 requests per day. Accounts without credit get ×1 of the daily quota; accounts that have topped up get ×3.
What happens when I exceed the free quota?
Requests on free-quota models continue at the normal paid rate if you have credit; otherwise they are rate-limited until the quota resets.
Is the API OpenAI-compatible?
Yes. Point the official OpenAI SDK at https://bazaarlink.ai/api/v1 and everything works — chat completions, streaming, tool calling.
Can AI agents get their own API key?
Yes. Agents can POST to /api/v1/agents/register and receive a free API key programmatically — no human in the loop.
