How to assess Expansion Chat's routing role? Don't jump to conclusions based on price or a single speed test alone. We recommend placing this provider on the same evidence chain: Are model endpoints enumerable? Are Claude / OpenAI / Gemini protocols truly passthrough? Is there scraping evidence for public pricing? Is the network region stable? Are there enough samples on the rankings? Only when evidence is sufficient and stable is it suitable as a primary route; when pricing has advantages but protocols or availability still need observation, it's better suited as a backup or testing route.
Primary: protocol + availability + pricing all evidenced Backup: pricing or coverage advantage but needs review Watch: insufficient samples or recent fluctuation Avoid: delisted, unreachable, or severe anomalies

  3. Test a request:
    curl https://api.expansion.chat/v1/chat/completions -H "Authorization: Bearer YOUR_KEY" -H "Content-Type: application/json" -d '{"model":"gpt-4o-mini","messages":[{"role":"user","content":"hello"}]}'

❓ Frequently Asked Questions

Is Expansion Chat reliable?

Currently fewer than 3 tests, insufficient data samples. Refer to the "Real-time Detection Data" section for the latest reports or test yourself.

How much does Expansion Chat cost?

Expansion Chat does not have a public unified price list; log in to the backend for specific pricing. Compare similar sites on the Price Comparison Page for reference.

Which models does Expansion Chat support?

Expansion Chat's model list is not publicly enumerated yet; log in to the backend to view.

What's the difference between Expansion Chat and official?

Official (OpenAI/Anthropic/Google) = first-hand pricing + stable direct connection + strict content moderation and account ban risk. Third-party relays = usually discounted pricing + domestic accessibility + but compounded availability, content moderation, SLA, and service shutdown risks. Which to choose depends on your cost sensitivity, content moderation requirements, and stability priorities. It is recommended to use official for critical paths + relays as backup.

Will Expansion Chat shut down?

We continuously monitor relay site reachability. Multiple consecutive failed detections within 30 days = high risk signal. Recommendations: ① Don't top up too much ② Rotate across multiple providers for critical services ③ Watch the Rankings warnings.
