x402-bazaar-agentkit

Check, then act — x402 Bazaar actions for Coinbase AgentKit.

Your agent checks a token before it buys, then swaps at the best price — from its own wallet. Nothing is held by us.

| Action | What it does | |---|---| | pre_trade_check | GO / HOLD / STOP before buying a token on Base (honeypot and sell-tax simulation, owner powers, liquidity, deployer) or NEAR (keys, owner, pause, exit tested through NEAR Intents) | | swap_on_base | Best-price swap on Base, routed by 0x across Uniswap, Aerodrome, Balancer, Curve and more — executed from the AgentKit wallet (approves exactly the amount sold). Unknown tokens get a sellability check; honeypots are refused | | cross_chain_swap | Swap across chains through NEAR Intents — NEAR, Base, Ethereum, Solana, Bitcoin… Paying from Base, the wallet sends the deposit itself | | cross_chain_swap_status | Pending, processing, SUCCESS, REFUNDED or FAILED | | x402_bazaar_call | Any of the 150+ services in the catalog: wallet and approval audits, NEAR portfolio / staking yields / lending health, web search, page-to-JSON, OFAC screening… |

Install

npm install x402-bazaar-agentkit @coinbase/agentkit

import { AgentKit } from "@coinbase/agentkit";
import { x402BazaarActionProvider } from "x402-bazaar-agentkit";

const agentkit = await AgentKit.from({
  walletProvider, // any EvmWalletProvider on Base mainnet
  actionProviders: [
    x402BazaarActionProvider({ creditToken: process.env.X402_CREDIT_TOKEN }),
  ],
});

Paying

• Credit token (recommended): buy once at 402.com.tr/credits — with USDC on Base, a card, or from NEAR — and pass it as creditToken. Each call debits its price; no signing per call.
• No token: each call is paid over x402 in USDC on Base, signed by the AgentKit wallet.

Calls cost $0.002–$0.10. Swaps carry a small service fee inside the swap itself, shown in every quote. If a call fails, it is not charged.
