Unified API 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 (x402 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.

Agentic 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 agentic payment network enables this using stablecoin (USDC) micropayments, so agents can pay for exactly what they use in real time.

x402 and MPP are complementary payment protocols for agentic commerce. x402 is an open standard for internet-native payments: when an agent requests a paid resource, the server responds with HTTP 402 ‘Payment Required’ and a payment offer; the agent’s wallet settles in stablecoins and the request completes in a single round-trip. An extension to x402 also supports batch transactions for high-throughput workloads. MPP (Machine Payment Protocol) is a broader open standard proposed to the IETF that supports multiple payment methods — stablecoins, cards, and bank transfers — in any currency, with first-class primitives for receipts, idempotency, and refunds. Think of x402 as the fast lane for crypto-native API payments, and MPP as the universal framework that works with any payment method. AIsa supports both protocols, so agents can choose whichever fits their use case.

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.
