Your first paid call in 60 seconds

No signup. No API keys. Your wallet is your account: pay per call in USDC on Base via the x402 protocol. First call is free for new wallets on most tools.

1 · See what a tool costs (no wallet needed)

curl -s -X POST https://agentbit.app/v1/web/search \
  -H 'Content-Type: application/json' \
  -d '{"query":"x402 protocol"}'

You get HTTP 402 with a base64 PAYMENT-REQUIRED header: the exact price in atomic USDC units, the pay-to address, the network (eip155:8453) and the EIP-712 signing details.

2 · Pay and call — one function (Node)

npm i x402-fetch-pay

import { payAndCall } from 'x402-fetch-pay';

const res = await payAndCall('https://agentbit.app/v1/web/search',
  { query: 'x402 protocol' },
  { privateKey: process.env.AGENT_WALLET_KEY });

console.log(res.data); // paid, settled, done

The SDK reads the 402, signs an EIP-3009 USDC authorization for the exact amount (gasless for you) and retries. Fund the wallet with a few cents of USDC on Base — that's the whole setup.

3 · Or plug ALL tools into your agent

MCP (Claude, Cursor, any MCP client)

{
  "mcpServers": {
    "agentbit": {
      "type": "streamable-http",
      "url": "https://agentbit.app/mcp"
    }
  }
}

The agentbit_discover operation is free; paid tools take a _payment argument.

Vercel AI SDK / LangChain.js

npm i agentbit-ai-tools

import { agentbitTools } from 'agentbit-ai-tools/vercel';

const tools = await agentbitTools({
  privateKey: process.env.AGENT_WALLET_KEY });
// → every AgentBIT tool, ready for generateText()

Tool definitions are generated live from the catalog — new tools appear without upgrading the package.
