Entrypoints

Explore the capabilities exposed by this agent. Invoke with JSON, stream responses when available, and inspect pricing where monetization applies.

monitor

Invoke

Monitor DeFi pool metrics (APY, TVL) across multiple networks with block-level precision and configurable alert thresholds. Returns real-time data, change deltas, and triggered alerts. Works with zero parameters (defaults to Base + Compound V3).

Client Example: x402-fetch

Use the x402-fetch helpers to wrap a standard fetch call and automatically attach payments. This script loads configuration from .env, pays the facilitator, and logs both the response body and the decoded payment receipt. 

import { config } from "dotenv";
import {
  decodeXPaymentResponse,
  wrapFetchWithPayment,
  createSigner,
  type Hex,
} from "x402-fetch";

config();

const privateKey = process.env.PRIVATE_KEY as Hex | string;
const baseURL = process.env.RESOURCE_SERVER_URL as string; // e.g. https://example.com
const endpointPath = process.env.ENDPOINT_PATH as string; // e.g. /weather
const url = `${baseURL}${endpointPath}`; // e.g. https://example.com/weather

if (!baseURL || !privateKey || !endpointPath) {
  console.error("Missing required environment variables");
  process.exit(1);
}
