How do you manage multiple LLM API keys and base URLs?
I keep running into the same operational mess when testing LLM tools: every client wants a slightly different base URL, model name, API key, billing page, and protocol shape.
For quick experiments this is fine, but once you use OpenAI-compatible SDKs, Anthropic-compatible clients, Claude Code style setup, and terminal agents, the setup becomes noisy.
I am working on TokenHub as one prepaid key and one endpoint for these workflows. The launch goes live later today on Product Hunt.
I would love feedback from people building with multiple LLM providers:
- Do you prefer direct vendor keys, a gateway, or both?
- What makes you trust or distrust an API gateway?
- Is prepaid credit useful, or do teams mostly want invoices/subscriptions?
- What docs would you expect before trying this in a real project?
The quickstart is here if you want context:
