What it enables
The
zerion-0xskill teaches AI agents how to execute token swaps via the 0x API (SwapAPI v2 and Gasless API v2) directly from within Zerion Agent. An agent that hears "swap
500 USDC for ETH on Base via 0x" or "get me a gasless quote for 1000 ARB → USDC on
Arbitrum" can walk through the full price → quote → execute flow — choosing the right
signing path (AllowanceHolder, Permit2, or Gasless) for the user's context.
Zerion CLI commands it composes with
zerion wallet list— look up the taker address before fetching a quotezerion analyze— pre-flight balance check before swappingWhy the combination is useful
0x's Swap API v2 aggregates liquidity across 20+ EVM chains and exposes three swap flows:
AllowanceHolder (simplest; works with multisigs and smart contract wallets), Permit2
(time-limited approvals, EIP-712 signing), and Gasless (fee deducted from sell tokens —
no ETH needed). The live
0x-mcpMCP server keeps the agent grounded in current endpointbehavior, token addresses, and error codes at runtime. Zerion CLI provides the wallet
and portfolio layer on either side. Together: an agent can check balances, fetch a firm
quote, walk through the right approval + signing steps, and confirm the swap — without
leaving the CLI context.
