Let's be honest: everyone has heard about AI gateways and suspected it was a buzzword. Spoiler: it's what solves one of the biggest pains for teams in emerging markets — payment — in one shot.
The problem: your app uses GPT for one task, Claude for another, Gemini for extraction. Now you have multiple accounts, multiple dashboards, no unified view of cost.
What a gateway does: a single layer between your code and the models. One API key talks to one endpoint, and the gateway routes to GPT / Claude / Gemini.
Practical benefits:
- One key for everything — switch models by changing a string;
- Cost control — per-project limits, alerts, consolidated billing;
- Automatic fallback — if the main model fails, route to another;
- Local payment — in Brazil, PIX instead of international credit cards.
When you DON'T need it: single model, small app, no cost concerns.
When you DO: multiple models, bigger team, cost control, or international payment pain.
