Why Apiario Dev?

Built for Brazilian developers.

Four pillars that make Apiario Dev the most Brazil-adapted AI platform.

Cost Engineering

Optimized routing for cost/performance tradeoffs. Automatic fallback to cheaper models, batch + async pricing, and budget guardrails with hard limits per team. The cheapest way to run LLMs in Brazil without thinking about it.

Latency & Infra Advantage

Lower latency vs US-hosted APIs*. More stable performance for real-time apps: chat, voice agents, WhatsApp automation, and call centers. Infrastructure built for the Brazilian market.

* Except for APIs offered by closed international providers.

Local Model Ecosystem

Host and promote Brazilian models from universities and startups. A marketplace of fine-tuned models for OAB/legal exams, ENEM tutoring, and customer support scripts. The place where Brazilian AI builders publish and monetize.

Localised Pricing

Prices in BRL, paid with PIX with predictable pricing and nota fiscal for your CPF or CNPJ. No IOF tax, no exchange spread, no surprises.

How it works.

Simple integration, transparent billing.

1. Top up your credits

Add credits via PIX or credit card. Invest as much as you want — no minimum or maximum — and pay only in BRL.

2. Generate your Key

Create your account and get your unified API key in seconds. One single endpoint for dozens of global LLMs.

3. Choose your Model

Switch between OpenAI, Anthropic, Google or Llama by changing a single string in your code. Zero friction.
