XyncPay is a non-custodial protocol translation and settlement layer purpose-built for the AI agent economy. As autonomous AI agents begin transacting at scale, three incompatible payment protocols have emerged: x402 (Coinbase), MPP (Stripe/Tempo), and AP2 (Google). XyncPay translates between all three and settles every transaction in stablecoins, making cross-protocol agent commerce possible without custodial intermediaries.
How it Works: Developers integrate XyncPay's API using wallet-based authentication and start making calls immediately. No approval gates, no waitlist. When an agent needs to pay for a service, a product, or an API call, XyncPay accepts the payment request in whatever protocol the agent speaks, converts it into a standardized internal format, and routes it through the appropriate payment rail. Settlement executes atomically through XyncPay's verified FeeSplit smart contract: the fee is deducted onchain and the net payment is forwarded to the recipient in a single transaction. XyncPay never holds private keys, never custodies funds, and never touches user wallets.
Target Audience: Developers building AI agents that spend money autonomously and service providers accepting payments from AI agents. XyncPay is developer infrastructure, not consumer software; end users never interact with XyncPay directly.
Current Deployment: FeeSplit is live and verified on Base mainnet, with the first real stablecoin transaction confirmed onchain. The contract includes an emergency pause mechanism and has passed security audits with zero critical findings. Fee model: 1% per transaction with a $0.001 floor and $1.00 cap, all enforced onchain.
An AI agent built on one payment protocol (x402, MPP, or AP2) can pay a service that only accepts a different protocol. XyncPay translates the payment request and settles via stablecoins on Base in a single atomic transaction.
High-volume, low-value agent transactions (e.g., per-query data access, per-summary content retrieval) are economically viable through XyncPay's $0.001 fee floor, enabling thousands of daily micro-payments with predictable economics.
Service providers can add XyncPay's payment middleware to their API endpoints. AI agents pay per query or per request, with fees split onchain through the FeeSplit smart contract. Providers receive stablecoins directly without handling multiple payment protocols.
AI coding agents can autonomously purchase cloud GPU time from providers that accept different payment protocols. XyncPay handles the protocol mismatch and settles payment via stablecoins, returning proof of payment so the agent can access compute resources.
