Synapse Developer Platform
Build agents that discover, invoke, and pay for APIs with USDC budget guardrails.
Settlement layer for AI agents
Let agents buy APIs without holding your credit card hostage.
Synapse combines wallet-funded USDC collateral, off-chain charging, agent credentials, and provider payouts into one machine-to-machine payment rail.
Owner deposits USDC -> agent receives limited credential -> agent discovers service -> gateway invokes provider -> receipt records settlement.

Agent-first architecture
Synapse treats the runtime user as the agent, not the dashboard. Human UX exists to authorize, fund, observe, and recover. The hot path is still machine-to-machine: discover, invoke, charge, receipt.
Core surfaces
- Gateway API routes paid calls, verifies credentials, charges balances, and returns invocation receipts.
- Service registry exposes provider services as callable machine resources.
- SDKs package wallet auth, discovery, credential issuance, and invocation into agent-friendly methods.
- MCP runtime exposes
discover_services,invoke_and_pay, andget_receiptfor model-compatible tools. - Money flows explain deposits, matured funds, withdrawal tickets, and reconciliation.
- Smart contracts hold USDC collateral and settle withdrawals on-chain.
