OnRamperX is a non-custodial value router for AI agents and humans — the one MCP tool to onramp fiat to crypto, offramp crypto to fiat, swap any token across 80+ chains, and settle agent payments. - Onramp: buy USDC on Base with a US debit card / Apple Pay / Google Pay (Coinbase Headless Onramp v2), human-in-the-loop for the fiat tap. - Swap & bridge: convert ETH, SOL, USDT, or any token on any chain into USDC on Base in one signature via Relay (~2.7s median, cross-chain, gas-abstracted), earning claimable app fees. - Agent payments (x402): pay-per-call settlement in USDC on Base via the Coinbase CDP facilitator, listed in the x402 Bazaar. AP2 / a2a-x402 aligned. - Rail-selection engine: quotes every eligible rail and returns ranked, non-custodial paths with fees, ETA, KYC burden, and plain-English reasoning. - Wallets: provision a gasless, user-exportable CDP Embedded Wallet on Base. Non-custodial by design — the platform never holds funds mid-flow. Settlement centers on USDC on Base. Callable from Claude, ChatGPT, Cursor, and framework agents. Tools: get_route_quote, create_swap, check_swap, create_onramp_session, provision_wallet. Built on MCP 2025-06-18, A2A 0.3, x402 v2, OAuth 2.1 (RFC 9728 PRM + RFC 8414 + RFC 7591 DCR + PKCE-S256) with a client_credentials PAT for framework agents.
