Kaopu API

Kaopu API sits in the API gateway layer, not in the application layer. If you are a developer who has been juggling three or four AI provider SDKs, signing up for a single key that reaches all of them is genuinely useful. The dashboard gives you a central place to see usage and spend across providers, which is a real pain point for teams that have adopted AI ad hoc. Where it shines: the free tier is generous enough for prototyping, and automatic fallback means you do not wake up to a broken app because one provider had a hiccup. The admin dashboard makes it easy to issue and revoke keys per project or per developer, which gets tedious with direct provider accounts. As you scale, the routing rules based on cost or latency can meaningfully cut your bill, and the caching helps with repeated prompts. Where it struggles: documentation is clearly thinner than competitors like OpenRouter or LiteLLM, so expect to figure some things out yourself. At high call volumes, the per-call pricing may end up costing more than going direct to each provider, so the convenience has a price. Also, if you only call one model, a gateway is overkill. In the long run, the value is the consolidation and the resilience features, not the models themselves. You are still paying for what is essentially a pass-through, so the math only works if you are using multiple providers or need the fallback / routing logic.
