API RELAY / MODEL GATEWAY

Smarter relay,faster creation

Full-power AI, within reach

Use frontier AI models for a fraction of the official price.

Passion8 is an AI API relay for developers, creators, and AI tool users. Connect OpenAI-compatible APIs, Claude Code, Codex, Gemini, and CC-Switch through one stable base URL.

# Keep the official SDK. Replace only the gateway.

client = Anthropic(
    api_key="sk-...",

MODEL TABLE

Model routing without vague platform talk

Compare the line items that matter before routing production traffic: input, output, cache reads, and the client each model fits best.

RELAY SYSTEM

Built for people who ship with AI tools every day

Official model access

Full GPT-5, Claude, and Gemini line-up — original models, no quality downgrade, no wrappers.

Transparent pricing

Pay the official number in RMB instead of USD, billed per token with no hidden margin.

Global acceleration

Cloudflare edge network with multi-line BBR routing keeps latency low and calls reachable.

Secure key handling

Independent API keys, encrypted at rest, over full HTTPS transport — privacy first.

BASE URL CHECKLIST

Choose a client, copy the working example

No platform buzzwords — just what you can actually use: real tools, real base URLs, real configuration you can copy and run.

Anthropic-compatible clients keep their SDK calls. Replace the base URL and API key.

Python (Anthropic)
import os
from anthropic import Anthropic

client = Anthropic(
    api_key=os.environ["PASSION8_API_KEY"],
    base_url="https://passion8.cc",
)

resp = client.messages.create(
    model="claude-opus-4-8",
    max_tokens=1024,
    messages=[{"role": "user", "content": "hello"}],
)

print(resp.content[0].text)

OUR NAME

Passion plus infinity

Passion8 reads as passion and the infinity of 8 — the belief that when access stops getting in the way, what people can build has no ceiling. We keep the path between your tools and the best models short, so the work stays on the ideas.

Frequently asked questions

Do I need to change my code?

No. Keep your existing SDK and request shape — point the base URL at Passion8 and swap in your key. Anthropic-style and OpenAI-compatible clients both work unchanged.

Which models and clients are supported?

GPT-5, Claude, Gemini and new flagship models, used from Claude Code, Codex, CC-Switch, the OpenAI SDK, and your own agents through one stable endpoint.

How is billing calculated?

Token-based, settled against official model pricing with no hidden margin. Usage, cache reads and per-request cost stay visible so reconciliation matches what you expect.

Is my key and traffic secure?

Each key is independent and revocable, all traffic is HTTPS, and usage boundaries are explicit. Keys never need to leave your environment beyond the request itself.
