ApiFlux
ApiFlux's core pitch — one key, over a hundred models, automatic failover, priced below list — is a common shape for this category right now, and the OpenAI-compatible endpoint makes switching low-friction for anyone already using that SDK. The discount and reliability claims depend entirely on ApiFlux staying solvent and fast as a middleman, which is a real question for any small routing layer sitting between you and the model providers.
Pros
- OpenAI-compatible endpoint means minimal code changes to switch
- Automatic failover across providers if one goes down
- Transparent, published discount (85% of list price) rather than an opaque markup
Cons
- No subscription or committed-spend option, only a prepaid balance
- Company ownership, founding team, and country are not disclosed on the site
- Adding a third-party gateway is an extra point of failure between you and the model provider
