AIsaEscrow

AIsaEscrow is a payment solution designed for pay-per-usage applications, positioned as an alternative to fiat and x402 payments. Our key differentiator is AIsa AI Marketplace, a fully production-ready SaaS platform that delivers a unified API across LLM inference, search, and vertical-specific data sources. Live since late last year, the platform enables us to experiment with and deploy novel payment primitives in real production environments from Day One. Traditional payment rails struggle with high-frequency, low-value transactions due to fees, chargeback risk, and reconciliation overhead. We also see strong demand from our users - primarily developers - for stablecoin payments. In practice, traditional payment fees of 2.9% + $0.30 significantly erode margins, making any top-up below $5 economically non-viable. An on-chain escrow model addresses these constraints by separating funding from consumption: users pre-fund an account, usage accrues as high-frequency microcharges, and balances are reconciled through automated settlement and debits. Users top up their accounts by depositing USDC into an escrow smart contract, with each escrowed balance mapped to a corresponding user ID in the AIsa AI Marketplace. Usage-based microcharges—often fractions of a cent per API call—are recorded in real time within a billing database. Settlement and disbursement operate on a 24-hour cadence. During each settlement window, total usage per user is aggregated, verified, and signed by a designated settler wallet. The verified charges are then deducted from each user’s escrowed balance accordingly.
