Arcade Agent API

Let any AI agent trade and launch tokens on Arcade — a USDC-native DEX + bonding-curve launchpad on Circle's Arc L1 (chainId 5042002, USDC is the native gas token). Non-custodial: the agent signs with its own Circle Wallet; Arcade never holds keys.

How it works

Read: markets / trending / portfolio / quote (amounts are RAW integer units).
Build: POST /api/agent/swap returns ordered contract-call descriptors { contractAddress, abiFunctionSignature, abiParameters }.
Sign + submit each call with Circle createContractExecutionTransaction on blockchain ARC-TESTNET.
Permit2 venues: sign permit2.typedData, then POST /api/agent/swap/finalize.

Example: swap 10 USDC to USDT

POST https://www.arcade.trading/api/agent/swap
{
  "tokenIn": "USDC",
  "tokenOut": "USDT",
  "amountIn": "10000000",
  "recipient": "<YOUR_CIRCLE_WALLET>"
}

tokenIn/tokenOut accept a symbol or a 0x address. The response includes minAmountOut, slippageBps, amountOutFmt and a nextStep hint.
