What is PleumRouter?

Service definition, audience, scope and limits.

PleumRouter is an AI API gateway from Korea that lets you use multiple LLMs (OpenAI, Anthropic, Google, xAI, DeepSeek and more) through a single OpenAI-compatible API. You keep your existing OpenAI SDK and change only the base_url; usage is billed in KRW prepaid credits, with automatic provider failover and optional PII masking.

Who it is for

Korean developers and teams (individual or business) who want multiple LLMs behind one OpenAI-compatible API — especially those who need KRW billing without foreign cards, or want to manage per-provider keys and billing in one place.

Team usage (member invites, organization credits, usage aggregation) and CLI coding-agent integrations (Claude Code, Codex, etc.) are supported.

How to start

In your existing OpenAI SDK code, change only the base_url and API key.

code

from openai import OpenAI

client = OpenAI(
    base_url="https://apirouter.pleum.ai/v1",
    api_key="pleum_...",
)

resp = client.chat.completions.create(
    model="gpt-4o-mini",
    messages=[{"role": "user", "content": "Hello"}],
)

See the [object Object] and [object Object] for full setup. You can sign up without registering a card; one free onboarding call is provided before your first payment.

Costs and payment conditions

Usage is settled in KRW prepaid credits. Pricing = token price + model markup, plus a platform fee on credit top-ups and an FX markup on KRW conversion. Failed calls are not billed.

Current fee numbers and the exact formula are published live on the [object Object].

Scope and limits

Not every model or feature is supported — check each model's supported parameters and features in the model catalog.
Inference location varies by provider; cross-border transfer destinations are published in Article 5 of the privacy policy.
Electronic tax invoices for business members are in preparation (Korean business verification can be completed in advance).
The service currently targets the South Korean market (KRW payments); Japan and Brazil are planned.
PII masking is optional and has a defined scope and exceptions — see the masking guide.
