What it is

AgentKit turns the 0xGasless platform into a set of agent tools. An agent gets a KMS-custodied wallet (no private key in your process), a server-enforced spending policy, and actions to:

• Pay — send stablecoins (USDC/XSGD) and pay any x402 API on the internet, gaslessly, under spend caps.
• Do — search and run tools from the 0xGasless Tool Gateway (backed by Apify's actor marketplace): browse the web, scrape pages, run search — paid per call from the agent's wallet.
• Be trusted — mint an ERC-8004 on-chain identity, check another agent's reputation before paying it, and leave feedback.

The agent needs zero native gas token — the 0xGasless facilitator pays the gas. It only spends the stablecoin.

Two modes

Install

npm install @0xgasless/agentkit

Quick start (platform mode)

import { Agentkit, AgentkitToolkit } from "@0xgasless/agentkit";
import { ChatOpenAI } from "@langchain/openai";
import { createReactAgent } from "@langchain/langgraph/prebuilt";

// 1. Configure — the API key (from your dashboard project) authenticates every
//    action; the wallet lives in 0xGasless KMS.
const agentkit = await Agentkit.configureWithPlatform({
  apiKey: process.env.OXGAS_API_KEY!,   // Dashboard → Project → Auth → API Key
  agentId: "my-first-agent",            // create with client.agents.create first
  chain: "avalanche-fuji",              // Avalanche is the primary network
});

// 2. Turn it into LangChain tools and hand them to your agent.
const tools = new AgentkitToolkit(agentkit).getTools();
const app = createReactAgent({ llm: new ChatOpenAI({ model: "gpt-4o" }), tools });

// 3. Let it work — it can now pay for what it needs.
await app.invoke({
  messages: [{ role: "user", content:
    "Find a tool that can read a web page, then read https://example.com and summarize it." }],
});

Behind that one prompt: the agent calls search_tools (free), picks the web reader, calls browse_web → which pays ~$0.05 in USDC from its custodied wallet via x402, settled on Avalanche by the 0xGasless facilitator → and gets the page back. All under the spending policy you set in the dashboard.

The actions

Money (platform mode)

• x402_pay — pay a recipient in USDC/XSGD, gasless, settled by the facilitator
• pay_api — fetch any URL and auto-pay if it responds 402 (with a mandatory maxValue cap)
• smart_transfer — transfer USDC/XSGD to an address
• get_spend_status — read the agent's caps + remaining daily budget
• get_agent_wallet — address, chain, balances

Internet hands (Tool Gateway)

• search_tools — discover a tool for a task (free)
• call_tool — run any gateway tool, paying per call under a cap
• browse_web — read/search the web (via the gateway's browser tool)
• http_request — a guarded plain HTTP call (https-only, SSRF-protected) for free/public APIs

Trust (ERC-8004)

• register_identity — mint the agent's on-chain identity (gas sponsored)
• check_agent_reputation — score + confidence + basis, before you pay another agent
• give_agent_feedback — record +/- feedback after an interaction

DeFi (both modes) — balances, token details, swaps & bridges (deBridge), disperse, market data (DexScreener), and more. Call getAllAgentkitActions() to enumerate the full set at runtime.

Self-custody mode

const agentkit = await Agentkit.configureWithWallet({
  apiKey: process.env.API_KEY!,
  privateKey: process.env.PRIVATE_KEY as `0x${string}`,  // you hold this key
  chainID: 43113,
});

Same toolkit; actions that require the platform (payments, tools, identity) will say so. run_terminal_command is disabled unless you explicitly pass unsafeTerminalAccess: true (only in a sandbox you control).

Supported networks

Avalanche C-Chain (43114) and Avalanche Fuji (43113) are the primary, fully supported networks. Base (8453), Sonic (146), and BSC (56) are available for self-custody DeFi actions.

Migrating from 0.0.x

Platform mode and the money/tool/trust actions are new in 1.0. Your existing configureWithWallet code keeps working. See MIGRATION.md.
