Budget & cost control for AI agents: hard per-agent spend caps, rate limits,
idempotency, and human-in-the-loop approval — enforced before each LLM call, not
after the invoice. One hosted MCP endpoint (no proxy or self-hosting), settled
via x402 (USDC on Base).
A budget-bound x402 payment wallet for AI agents: it autonomously pays HTTP 402 payment-gated URLs across every major chain (EVM, Solana, and many non-EVM families). Self-custodial and backendless, your key, your RPC, with spend caps enforced before any on-chain send.
Enables AI agents to autonomously request services from other specialized agents and compensate them via x402 micropayments. Demonstrates a Machine-to-Machine economy using A2A protocol for agent communication, MCP for context management, and blockchain-based payments on Base network.
