The fastest way to go from "what's an AI API" to "my app uses four models."

Step	What happens
Step 1: Playground	No signup. 15 models. Pick one. Type words. See response.
Step 2: Register	GitHub → authorize → done. 5 seconds.
Step 3: Onboarding	API key + curl + Python code. Copy, paste, run.
Step 4: Production	Same code. Different model string.

Step 1 → Step 2: The one click that matters

No email. No password. No 6-digit code. You try the playground, you
like it, you click GitHub → authorize → you have a key. Five seconds.

Before GitHub OAuth, registration was 6 steps. 1.4% completion rate.
After: one click. 19% conversion from playground to registered user.

Step 2 → Step 3: The bridge

After login, you don't land on an empty dashboard. You land on a page
that says "Your account is ready." Your API key is right there. A curl
command you can paste into a terminal. Python SDK code to copy.

curl https://aibridge-api.com/v1/chat/completions \
  -H "Authorization: Bearer mb-xxx" \
  -d '{"model":"deepseek-chat","messages":[{"role":"user","content":"Hello"}]}'

30 seconds from login to first response. The 68% drop-off between
registration and first API call? That's the gap this page closes.

Step 3 → Step 4: The one-string change

Once you've run the curl command and seen it work, production is this:

import openai
client = openai.OpenAI(
    api_key="mb-xxx",
    base_url="https://aibridge-api.com/v1"
)

# 90% of traffic — $0.27/M
client.chat.completions.create(model="deepseek-chat", messages=msgs)

# Multilingual work
client.chat.completions.create(model="qwen-max", messages=msgs)

# Deep reasoning
client.chat.completions.create(model="glm-4-plus", messages=msgs)

# 1M context, always thinks
client.chat.completions.create(model="kimi-k3", messages=msgs)

Same import openai. Same .create() call. Same response format.
The only thing that changes is the model string. No new SDKs.
No new environment variables. No new accounts.

The stuff that supports all of this
Prompt library — 24 ready-to-use prompts. Six categories. "Find
bugs → Kimi K3." "Translate → Qwen Max." One click fills the
playground.

Dashboard — usage bar that goes from polite to urgent. Blue below
50%, orange at 80%, red flashing at 90%. The upgrade button gets
harder to miss exactly when you need to act.

Anti-bot protection — 5 lines of in-memory rate limiting took
verification endpoint abuse from 2,600 requests/day to zero.

Free tier: 500K tokens/month. No credit card.
