# Frequently Asked Questions - AIsa Unified API

This page answers common questions about the AIsa unified model gateway, compatibility, pricing, and infrastructure.

## How does AIsa compare to OpenRouter or LiteLLM?

While AIsa shares the core functionality of an LLM router (aggregating multiple models behind a single API), AIsa goes significantly further by integrating 100+ non-LLM data APIs (Twitter, Financial, Search), an MCP server, and native stablecoin micropayments for autonomous agents.

AIsa is specifically built as the infrastructure layer for the agentic economy, where agents not only need to think (LLMs) but also act (data APIs) and transact (Machine-to-Machine Payments).

## Do I need to change my existing OpenAI code?

No. AIsa is fully API-compatible with the OpenAI specification.

If you are using the official OpenAI Python or TypeScript SDKs, you only need to change your `base_url` to `https://api.aisa.one/v1` and authenticate using an [AIsa API Key](/docs/guides/dashboard/overview). All standard parameters like `temperature`, `top_p`, and streaming responses work exactly as expected.

## How is pricing calculated?

AIsa uses a unified usage-based billing system. You can pay as you go or choose a subscription plan (Builder or Team); see [aisa.one/pricing](https://aisa.one/pricing) for plan details.

* **LLM inference** is billed per token.
* **Data APIs** are billed per request: some at a fixed per-call rate (e.g. Open-Meteo, CoinGecko), others metered from the provider's cost, so the price can vary with what a call returns (e.g. Twitter, Tavily, Search, Financial).

All usage is deducted from your single, centralized account balance. See the [Pricing Overview](/docs/guides/pricing) for how billing works; current model prices are on [aisa.one/models](https://aisa.one/models).

## How do AIsa's LLM prices compare to OpenRouter?

The docs do not publish prices. Current AIsa prices for every model are on [aisa.one/models](https://aisa.one/models); compare them with OpenRouter's live pricing. For the feature comparison, see [AIsa vs. OpenRouter](/docs/guides/compare/openrouter).

## What models are available on AIsa?

AIsa provides a single gateway for the live model catalog — 124 models as of September 30, 2026. Current families include OpenAI GPT, Anthropic Claude, Google Gemini, xAI Grok, DeepSeek, Alibaba Qwen and Wan, Moonshot Kimi, MiniMax, Zhipu GLM, ByteDance Seed, Seedream and Dreamina, Tencent Hunyuan, StepFun, Xiaomi MiMo, and Jina embeddings.

For a complete and up-to-date list of exact model IDs, context windows, endpoints, capabilities, and billing notes, visit the [supported model catalog](/docs/guides/models) and [AI Model Pricing](/docs/guides/pricing/ai-model-pricing-llm-inference) documentation.

## How do I get started?
