One API for everything
The request format you already know from OpenAI, behind a single cn8 key. One key, every modality, one bill — no per-vendor glue.
Without cn8
- A different vendor, SDK and key per modality
- Separate dashboards, invoices and rate limits
- Glue code for auth, retries and usage tracking
- Re-integration every time you switch models
With cn8
- One key across chat, image, video, voice & text
- One usage-based credit balance, one bill
- Unified auth, streaming, usage and webhooks
- Swap models without rewriting your stack

Modalities
Free credits to start
Ship the whole feature, not just the call
Most AI APIs stop at the endpoint. cn8 also ships the application layer — embeddable apps, agents and a knowledge base — so a chatbot on your docs is an afternoon, not a sprint.
Embeddable chat & search widgets
Configure an app in the dashboard, drop one script tag on your site. Domain allow-lists, localization and analytics come built in.
Grounded in your knowledge base
Upload documents or crawl your website into collections — chat and search answer from your data, no vector-DB plumbing.
Agents & ready-made templates
Compose multi-step agents with sub-agents, or start from app templates and customize from there.
<!-- A RAG chatbot on your site — no backend required -->
<script
src="https://apps.cn8.io/chat/embed.js"
data-app-id="your-app-id"
async
></script>The widget streams answers from your knowledge base and respects the domains, languages and theme you set in the dashboard.

Spend control
Credit-based budgets with low-balance alerts and optional auto top-up.
Usage analytics
Per-key and per-service usage and cost visibility from day one.
Webhooks
Subscribe to job lifecycle events instead of polling long-running tasks.

Frequently asked questions
Everything you need to know before your first call.
What exactly is cn8?
cn8 is a unified AI API: 40+ production-ready AI products across text, image, video and voice — chat & RAG, agents, LLM completions, image generation, dubbing, TTS and more — behind a single API key with unified credits and billing.
Is the API really OpenAI-compatible?
Yes. LLM completions accept OpenAI-style chat payloads and stream server-sent chat.completion.chunk events, so you can point an existing OpenAI client at the cn8 endpoint and change one line.
Which models can I actually call?
LLM Completions covers OpenAI and Anthropic out of the box — GPT-5, GPT-4.1, GPT-4o and o-series reasoning models, plus Claude Opus 4.7, Sonnet 4.6 and Haiku 4.5 (with extended-thinking variants) — across budget, standard and premium tiers. Call GET core-llm-models for the live list with prices. Media products like image generation, TTS, dubbing and video run cn8's own production pipelines.
How does pricing work?
Usage-based credits. You start free with 100 test credits — no credit card required — and every API call draws from the same balance, whatever the modality. Top up as you grow, or talk to us about Pro and Enterprise plans.
What does a credit actually buy?
Credits are a single usage currency across every modality, so you don't juggle per-provider pricing. Each call deducts based on what it does — roughly tokens for chat & LLM, per-image for image generation, per-second for audio and video — and the exact cost of every call is shown in your dashboard usage. Your 100 free credits are enough to make your first test calls before you commit.
Is my data private and secure?
Your cn8 API key authenticates over TLS, and in the keyless browser demos the key never leaves the server — it is never exposed to the page. You can scope individual keys to specific products, set credit-based spend limits, and rotate or revoke keys anytime. See our Privacy Policy for data handling and retention details.
Do I need a different key for each service?
No. One cn8 key can unlock the whole catalog — and when you want tighter security, you can scope individual keys to specific products with per-product permissions.
Can I ship a chatbot or search without building a backend?
Yes. Configure a chat or search app in the dashboard, connect it to your knowledge base, and embed it on any site with a single script tag — domain restrictions, localization and analytics included.
How do I keep usage under control in production?
Every key gets usage analytics, credit-based spend control with optional auto top-up, scoped permissions and webhooks for job lifecycle events — all managed from the dashboard.
