Example Prompts

Once connected, try asking your AI:

• "What's the current gas fee estimate for a swap on Ethereum?"
• "Label this address — is it an exchange, mixer, or whale? 0x28C6c06298d514Db089934071355E5743bf21d60"
• "Analyze this wallet's on-chain activity and give me a risk score: 0x..."
• "Score this wallet's trading volume vs the average on-chain: 0x..."
• "Explain what permissions this smart contract is requesting before I approve it"
• "Is this wallet eligible for the upcoming airdrop?"

Direct x402 Usage (Node.js)

import { wrapFetchWithPayment } from "x402-fetch";
import { privateKeyToAccount } from "viem/accounts";
import { createWalletClient, http } from "viem";
import { base } from "viem/chains";

const account = privateKeyToAccount(process.env.WALLET_PRIVATE_KEY);
const walletClient = createWalletClient({ account, chain: base, transport: http() });
const fetch = wrapFetchWithPayment(globalThis.fetch, walletClient);

// Gas fee estimate — one of the most-called APIs in this domain
const resp = await fetch(
  "https://orbisapi.com/api/proxy/gas-fee-estimator-api-a96f58/estimate",
  { method: "POST", headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ chain: "ethereum", type: "swap" }) }
);
console.log(await resp.json());

OpenAI Agents SDK

Python:

from agents.mcp import MCPServerStreamableHttp
from agents import Agent, Runner

mcp = MCPServerStreamableHttp(url="https://orbisapi.com/api/mcp/crypto")

agent = Agent(
    name="Orbis Crypto Agent",
    model="gpt-4o",
    mcp_servers=[mcp]
)

result = await Runner.run(agent, "Browse available crypto APIs")
print(result.final_output)

TypeScript:

import { Agent, run } from "@openai/agents";
import { MCPServerStreamableHttp } from "@openai/agents/mcp";

const mcp = new MCPServerStreamableHttp({
  url: "https://orbisapi.com/api/mcp/crypto",
});

const agent = new Agent({
  name: "Orbis Crypto Agent",
  model: "gpt-4o",
  mcpServers: [mcp],
});

const result = await run(agent, "Browse available crypto APIs");
console.log(result.finalOutput);
