All endpoints require authentication via a Client API Key or Client Session Token (CST) passed as a Bearer token. ## Base URL `https://api.portalhq.io/api/v3` ## Authentication Include your Client API Key or Client Session Token as a Bearer token in the `Authorization` header of every request. ## Chain ID Format Chain parameters use either friendly names (e.g. `ethereum`, `solana`) or CAIP-2 format (e.g. `eip155:1`, `solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp`). When using CAIP-2 format in URLs, ensure the colon is URI-encoded (`%3A`). servers: - url: https://api.portalhq.io/api/v3 description: Production security: - bearerAuth: [] tags: - name: Clients description: Core client management endpoints - name: Wallet description: >- Read wallet state — balances, NFTs, transaction history, capabilities, and transaction details - name: Transactions description: Build, broadcast, and evaluate blockchain transactions - name: Funding description: Fund wallets with testnet tokens - name: Wallet Shares description: Manage signing and backup share pairs - name: Delegations description: Manage token approvals, revocations, and delegated transfers - name: Session Keys description: Manage EIP-7702 session keys for smart accounts - name: 0x description: Token swap endpoints powered by the 0x protocol - name: Yield.xyz description: Yield opportunities and staking actions powered by Yield.xyz - name: Li.Fi description: Cross-chain swaps and bridging powered by Li.Fi - name: Blockaid description: Transaction and address security scanning powered by Blockaid - name: Hypernative description: >- Transaction, address, token, and NFT security scanning powered by Hypernative - name: Noah description: KYC onboarding, payins, and payouts powered by Noah - name: Meld description: Buy and sell crypto with fiat through aggregated providers powered by Meld - name: EIP-7702 description: EIP-7702 account type detection and authorization management - name: Deprecated description: >- Legacy endpoints scheduled for removal.
