AgentPayAI is a multi-chain payment protocol and execution infrastructure engineered to revolutionize how AI services are consumed and monetized. It operates as a:

• Decentralized AI Compute Aggregator — Procures enterprise API inference access from leading AI providers (Anthropic Claude 3.5, Google Gemini 2.5, OpenAI GPT-4o)
• Micropayment Gateway — Enables sub-cent transactions with 1-click gasless EIP-3009 settlement via the x402 HTTP payment engine
• BOF Facilitator Integration — Integrates BOF (BotChain Open Facilitator), an open-source Rust microservice developed by AgentPay AI for off-chain signature verification (/verify) and gas-sponsored on-chain settlement (/settle) on BotChain EVM
• Autonomous Agent Infrastructure — Seamless deployment across BotChain's Autonomous AI Agent Network for human-to-agent and machine-to-machine interactions

Pay-Per-Prompt Billing & Single-Click UX

• Zero friction 1-click payment model (0 gas, 1 wallet signature popup)
• Dynamic pricing per service: 1.0 $APAY for Chat, 2.0 $APAY for Code Audits, 5.0 $APAY for Image Generation
• Sub-second AI response latency via off-chain EIP-712 signature verification before on-chain settlement

Multi-Chain & Protocol Compliance

• Gasless EIP-3009 (transferWithAuthorization) settlement on BotChain EVM (Testnet 968 & Mainnet 677)
• ERC-8004 identity registry and ERC-8021 builder attribution (0x8021 suffix)
• Multi-token asset support ($APAY, $USDT)

Agent-First Design

• Built for autonomous agent networks and BotChain integration
• Programmatic task delegation (/api/botchain/relay) and machine-to-machine payment coordination
• Enterprise AI provider routing and load balancing

Tokenomics & Sustainability

• Native $APAY utility token (0xFd7bF688d5a772A81DfE39da502F69FD99cE92c7)
• Automated fee routing, buyback-and-burn mechanisms, and BOT Infrastructure Grant alignment
