Capability Layer for the Agentic Economy

An AI API gateway is a single endpoint that routes requests to multiple LLM providers — like OpenAI, Anthropic, Google Gemini, and DeepSeek — without requiring separate integrations for each. AIsa acts as a unified AI API gateway that gives developers access to 50+ models and 100+ specialized data APIs through one OpenAI-compatible endpoint. You write your code once, and AIsa handles routing, failover, and billing across providers.

Unlike pure routing proxies, AIsa combines three layers into one platform: a unified model gateway (similar to OpenRouter or LiteLLM), a composable skills marketplace for agent capabilities, and an agentic payment network (Circle Nanopayments and MPP) that lets AI agents pay each other in USDC. OpenRouter focuses on model access and pricing transparency. LiteLLM is an open-source proxy you self-host. Portkey emphasizes enterprise observability and guardrails. AIsa is the only platform that bundles API routing, agent skills, and crypto-native payments into a single infrastructure layer.

Yes. AIsa's API is fully OpenAI-compatible, which means you can use the official OpenAI Python or Node.js SDK by simply changing the base URL to AIsa's endpoint. No code rewrites needed. This also means any tool or framework that supports the OpenAI API format — like LangChain, LlamaIndex, or CrewAI — works with AIsa out of the box.

AIsa offers pay-as-you-go pricing with no minimum commitments. New accounts receive $2 in free credits. You pay per token at competitive rates that vary by model and provider. Unlike OpenRouter (which adds a markup per token) or Portkey (which charges a platform subscription), AIsa's pricing includes access to the skills marketplace and agentic payment infrastructure at no additional platform fee.

Machine-to-machine payments allow AI agents to autonomously pay for services, data, and compute without human intervention. As AI agents become more autonomous — booking travel, purchasing data, calling APIs — they need a way to transact programmatically. AIsa's payment network enables this using stablecoin (USDC) micropayments, so agents can pay for exactly what they use in real time.

Circle Nanopayments is Circle's USDC-based system for fast, low-cost machine payments, designed for use cases like paid APIs and AI agent transactions, while the Machine Payments Protocol (MPP) is an open standard for machine payments over HTTP that aims to support multiple payment methods through a common protocol layer; Circle Nanopayments is optimized for crypto-native USDC micropayments, whereas MPP is a broader, payment-method-agnostic framework, and both are described publicly in connection with HTTP 402-style payment flows for machine-to-machine transactions on the web.

Skills are composable, plug-and-play capabilities that AI agents can call on demand. Think of them as specialized micro-services: a 'web search' skill, a 'PDF extraction' skill, a 'flight booking' skill. Developers can publish skills to AIsa's marketplace and earn revenue every time another agent uses them. Agents can chain multiple skills together to complete complex workflows without custom integration work.

AIsa Foundry is a managed hosting environment for deploying autonomous AI agents. Instead of provisioning servers, managing containers, and wiring up API keys yourself, Foundry gives you a pre-configured runtime where your agent can access AIsa's full model gateway, skills marketplace, and payment network out of the box. It's designed for agents that need to run continuously and act autonomously.
