+# x402 Payments
+
+[x402](https://www.x402.org/) is an open payment protocol that uses the HTTP `402` status code to enable programmatic, machine-to-machine payments over HTTP. It allows servers to charge for API access without requiring buyer accounts, API keys, or traditional payment infrastructure.
+
+For example, an AI agent can pay 0.01 USDC per request to access a weather API, or a
+dapp can charge users a micro-payment to retrieve premium onchain analytics data.
+
+## ERC-7710 payments
+
+The standard x402 protocol supports direct token transfers (using ERC-20 Permit2 or EIP-3009).
+[ERC-7710](https://eips.ethereum.org/EIPS/eip-7710) extends this by enabling <GlossaryTerm term="Delegation">delegation</GlossaryTerm>-based
+payments from <GlossaryTerm term="MetaMask smart account">MetaMask smart accounts</GlossaryTerm>.
+
+With ERC-7710, a buyer's smart account creates a delegation that authorizes the facilitator
+to transfer tokens on their behalf. The buyer doesn't sign a direct token approval.
+Instead, they sign a delegation that the facilitator redeems during settlement.
+
+This approach enables buyers to pay from MetaMask wallet.
+Buyers can restrict delegations to specific facilitator addresses, amounts, and time windows
+using <GlossaryTerm term="Delegation scope">delegation scopes</GlossaryTerm>.
+They can also create long lived delegations that allow recurring payments without re-signing
+for each request.
+
+Learn more [ERC-7710 delegations](../../concepts/delegation/overview.md).
