Use this page when you need a working Python starting point for OpenRouter, then validate quota and model names in the official console before production.

Open official provider → Get one OpenAI-compatible key → Compare API gateway options →

Quick verdict

Free API: Free models
Rate limits: 20 RPM
Best model starting point: Free Models (多个)
Mainland China access: proxy/relay likely needed

Provider fit matrix

Best fit Fast provider evaluation, prototypes, and fallback routing

Watch out Free credits and rate limits can change without warning

Production fallback Keep at least one compatible backup provider before shipping

OpenRouter buyer intent notes

Who should care

Best for model shopping, fallback routing, BYOK-style experimentation, and teams that want many models behind one OpenAI-compatible API.

Decision trigger

Use OpenRouter when model coverage and routing flexibility beat direct-provider simplicity.

Watch out: Compare markups, rate limits, provider routing behavior, and free-model reliability before production.

Production readiness checklist

Quota gate Start inside Free models; log usage before adding retries or batch jobs.

No-card check Try the free path first, then confirm whether billing is required for API keys, higher RPM, or production endpoints.

Regional smoke test Run signup, dashboard, DNS, TLS, and first API call checks from mainland China before launch.

Source freshness Snapshot date: 2026-06-01; official quota and pricing can change without notice.

Python setup snapshot

Start with the smallest possible chat completion, then move the key to your server-side secret manager before production.

from openai import OpenAI

client = OpenAI(
    api_key="your-openrouter-key",
    base_url="https://openrouter.ai/api/v1"
)

response = client.chat.completions.create(
    model="meta-llama/llama-3.3-70b-instruct:free",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)

Free API and pricing notes

Free models

Some models are completely free, no payment needed

Access and production risk

Relay or proxy may be needed

Requires proxy. Aggregates 400+ models, one key for all.

How to set it up

Create or locate your provider API key in the official dashboard.

Install the OpenAI-compatible Python SDK or the provider-supported SDK.

Set the API key in an environment variable instead of hard-coding secrets.

Run a small OpenRouter chat completion with Free Models (多个).

Watch free credits, RPM/TPM limits, response shape, and error messages before scaling.
