Testing 200+ LLMs Without Losing Your Mind: One Gateway for Keys, Logs and Failover

If you've ever tried to seriously evaluate multiple LLM providers, you know the drill: another signup form, another API key format, another billing page, another rate-limit policy. Before you write a single line of your actual app, you've already spent days on plumbing.

This post describes how we consolidated all of that into a single gateway — and how you can try it with a free token trial.

The problem

  • N providers = N sets of credentials to rotate and protect
  • Slightly different APIs (chat completions vs responses vs vendor-specific quirks)
  • No unified view of what each call cost, which models were actually used, and how often the cache saved tokens
  • One provider's 429 or 504 can kill your request flow unless you build retries yourself

The approach: one OpenAI-compatible gateway

APIGOTO sits between your app and the model vendors:

  1. Unified endpoint — point your existing OpenAI client at one base URL, switch models by name.
  2. Credential management & health checks — platform credentials are monitored; unhealthy or rate-limited credentials are taken out of rotation automatically.
  3. Failover with a retry chain — on a 429 or 504 the gateway retries with another vendor/credential when available, and logs the full chain so you can see exactly what happened.
  4. Usage accounting — per-call logs with input/output/cache-read tokens, cost and cache-hit rates, per user and per model.
  5. A desktop client — for teammates who never want to see an API key.

The free trial

We're running a free TOKEN trial covering 200+ models. The exact quota, validity and eligible models change over time, so check the current rules on the site rather than trusting any screenshot (including ours).

Who this is for

  • Developers evaluating multiple models for a project
  • Small teams that want one place to manage model access and audit usage
  • Non-technical users who'd rather use a client than an API

Questions and feedback welcome in the comments — especially on retry/failover design and how you'd want usage accounting to look.
