# Agnic > Financial infrastructure for autonomous AI agents — wallets, x402 payments, identity, and AI gateway. Agnic provides the missing economic layer for AI agents: autonomous wallets (AgnicPay), a paid API marketplace (AgnicHub), on-chain identity (Agnic.ID), and access to 340+ AI models. Agents can send USDC, trade tokens, call x402-enabled APIs, manage email, and verify identity — all via CLI, REST API, or MCP server. ## Skill Guide - [AI Agent Skill Guide](https://agnic.ai/skill.md): Complete machine-readable guide — install skills, configure MCP, use the REST API, initialize a wallet ## Documentation - [API Reference](https://docs.agnic.ai/docs/agnicpay-features): Full REST API documentation for AgnicPay - [Wallet Skills](https://github.com/agnicpay/agnic-wallet-skills): Open-source Vercel AI Skills for wallet, payments, email, identity, AI gateway - [Human Skill Page](https://agnic.ai/skill): Human-readable version of the agent guide ## Products - [AgnicPay](https://pay.agnic.ai): Autonomous wallet dashboard — fund, API keys, spending limits - [AgnicHub](https://agnichub.xyz): x402 API marketplace — discover and pay for services - [Agnic.ID](https://agnic.id): Agent identity — W3C DIDs, Verifiable Credentials, KYA - [Agnic Monetization](https://agnic.ai/showcase): Build AI apps, earn per request ## Integration Endpoints - MCP Server: `https://mcp.agnic.ai/sse` (Bearer auth) - REST API: `https://api.agnic.ai` - AI Gateway (OpenAI-compatible): `https://api.agnic.ai/v1` ## Quick Start for Agents Read https://agnic.ai/skill.md for complete instructions.
