# Call models with no API keys

Without a key in your code, calls are automatically routed through Agentuity's AI Gateway. Access OpenAI, Anthropic, Google, Groq, and more with higher rate limits, unified billing, and detailed cost tracking.

## Features

### Zero-config model access

Write model calls without API keys, env vars, or provider accounts. Agentuity's gateway handles routing, secrets, and rate limits automatically.

### No Keys Required

Without a key in your code, calls route through Agentuity's AI Gateway automatically. No secret management, no provider accounts to create. Access OpenAI, Anthropic, Google, Groq, Mistral, and more. Just start coding.

### Higher Rate Limits

Benefit from centrally managed rate limits that are higher than individual developer accounts. Swap providers or models with a single config change and unified billing across all providers.

### Deep Observability

Every request gets detailed telemetry via OpenTelemetry: token usage, costs, latency, error rates, and span-level debugging. Track model performance across providers and optimize your agent workflows with real data.

Built-in cost analysis and usage forecasting for predictable scaling.

## Use our keys, or bring your own

Agentuity's gateway automatically detects your requests and routes them to the right models; you'll only be charged for the tokens you use. Prefer your own API keys? No problem, we'll automatically detect and use them instead.
