RouterPlex: one API key for 25+ AI models

Every AI provider wants you to manage a separate account, learn a slightly different SDK, track its own quota, and pay its own invoice. Ship features against four or five of them and you're maintaining a small integrations department just to make API calls.

RouterPlex collapses all of that into one OpenAI-compatible endpoint.

What it does

• 25+ models, one endpoint — Claude Opus 4.8, GPT-5.5, Gemini 3.1, DeepSeek V4, and more, all behind the same URL and key.
• Keep your existing code — it speaks the OpenAI API, so you point base_url at RouterPlex and swap the model string. No new SDK.
• One prepaid balance, per-token billing — one invoice instead of eleven.
• Hard spend limits on every key — a runaway loop can't drain your balance.
• Automatic fallbacks — when a provider has an outage, requests route to a healthy model instead of failing.
• Per-key analytics — see exactly where spend goes.

Using it

Change one line and you're routed:

curl https://dub.sh/kbeaNNe \
  -H "Authorization: Bearer $ROUTERPLEX_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "model": "claude-opus-4-8", "messages": [{"role":"user","content":"Hello"}] }'

Want GPT-5.5 or DeepSeek V4 instead? Swap the model value. Same endpoint, same key, same bill.
