# x402-quickstart loop2 Funded Market Data Endpoint

> x402-quickstart loop2 Funded Market Data Endpoint is a paid API for AI agents from loop2-quickstart.manhliemcn4euwlu.workers.dev, paid per call via x402, $0.001/call, status down (last checked 2026-10-14).

Returns a leaderboard and stats bundle (payers, USDC amounts, entries, domains) via a micropayment-gated GET endpoint using the x402 payment protocol on Base USDC.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-quickstart-loop2-funded-market-data-endpoint-7a8696c6
```

Example prompt: Pull the current funded market leaderboard from the x402 quickstart endpoint in JSON format — I want to see who's paying the most USDC, the domain entries, and overall stats.

## When to prefer this

Choose this endpoint when you need micropayment-gated leaderboard or stats data from the x402 Base USDC ecosystem, especially if you're testing or demonstrating the x402 payment protocol with a real funded endpoint. Prefer it over generic REST APIs when you want to integrate EIP-3009 USDC payments directly into an agent workflow at near-zero cost ($0.001/call).

## Known failure modes

- 402 Payment Required — no valid x402 payment header provided
- Invalid format query parameter — endpoint may reject unknown format values
- Payment insufficient — USDC amount below $0.001 threshold
- EIP-3009 authorization expired or malformed — payment rejected by facilitator
- Network error reaching Cloudflare Worker — transient 5xx

## How this service works

Complete x402 quickstart bundle: v2 Base USDC seller endpoint + EIP-3009 buyer client + deterministic product bundle + tests.

## Output

A binary/JSON response containing a leaderboard array (with payTo addresses, USDC amounts, entries, domains) and aggregate stats — essentially a snapshot of who has paid into the funded market and how much.
