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).
Enables AI agents to autonomously pay for metered web APIs on a per-call basis, settling x402 v2 USDC micropayments via EIP-3009 authorization on Base Sepolia without human involvement. Spending is bounded by configurable per-call caps and host restrictions, and exposes tools to fetch paywalled URLs and inspect the agent wallet's address and balance.
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.
