Open x402funding rail

Pay amount + 1% · net to any EVM target

An open x402 funding rail: pay amount + 1% over HTTP 402, net forwards to any EVM target, optional public receipt. Coinbase already funds wallets inside CDP; this is for protocol-shaped deposits without a deposit.now API key.

deposit.now is an open x402 funding rail with optional public receipts — not a replacement for Coinbase wallet creation or CDP Fund.

  • Open x402 deposit call. Any agent with an x402 client can POST target + amount and pay over HTTP 402 — no deposit.now API key.
  • Any EVM target. Forward net funds to whatever address you pass — CDP wallets, EOAs, or another agent’s address. (Creating wallets is out of scope; pass a target you already have.)
  • Public receipts (when configured). Settlements can write a public receipt with payer, target, fee, and Basescan links. Requires storage env; forward is async and can fail.
  • Simple fee. Flat 1% of the net amount, paid as part of the x402 gross. No merchant tiers.
  • Honest fit vs CDP Fund. If you already run fully on Coinbase Agentic / Server Wallets, use their Fund skill. Use deposit.now when you want an open x402 rail + receipt URL outside that stack.
