Overview
Description from the maker (original English)
Country economic momentum score (GDP, inflation, unemployment) via x402 USDC micropayments.
PopNx MCP’s three pillars
These three are never merged into one score: opinions, measurements and popularity are different things.

Common questions
Is Macro Pulse X402 safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 3 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spec Driven Development, Remote Desktop Commander, aamio rendezvous

Macro Pulse — x402-paid API
An x402-protected endpoint that gives AI agents a computed "economic momentum score" per country. Built entirely on free, public-domain World Bank data (https://data.worldbank.org) — nothing here repackages a licensed/paid feed.
What it does
GET /macro-pulse/{country_code} (e.g. /macro-pulse/US) — price: $0.02/call
Pulls GDP growth, inflation, and unemployment trend data from the World Bank API and synthesizes a single directional "momentum" score + label (improving / stable / deteriorating), with the raw indicator history included for transparency.
Tested locally — confirmed the payment gate correctly returns HTTP 402 with valid payment requirements (scheme=exact, asset=USDC, network=Base) when no payment is attached, and the underlying data/scoring logic returns correct World Bank data.
What YOU need to do before this can earn real money
- Get a Base wallet address (Coinbase Wallet or MetaMask configured for Base). This is where USDC payments land. Set it as
PAY_TO_ADDRESS. NEVER share your private key/seed phrase with anyone, including me.
- Decide testnet vs. mainnet:
- Testnet (Base Sepolia,
NETWORK=eip155:84532) — what this is configured for right now. Safe to test with fake USDC, $0 real risk. - Mainnet (
NETWORK=eip155:8453) — real money. For mainnet settlement you need a facilitator that supports it. The publichttps://x402.org/facilitatoris testnet-only — for mainnet, sign up for a free Coinbase Developer Platform (CDP) account (https://portal.cdp.coinbase.com) and use their hosted facilitator + API key.
- Deploy it somewhere publicly reachable (a real domain/URL, not localhost) so agents and marketplaces can find it — happy to help with this once wallet + network choice are set.
- List it on a discovery layer — https://www.x402scan.com or https://x402.org's Bazaar so agents can find and pay for it automatically. Also add a
/.well-known/x402manifest for auto-discovery.
Realistic expectations
At $0.02/call, this needs real volume (hundreds to thousands of calls) to add up to meaningful money. Treat this as a slow-build side project, not a quick win — see prior discussion for realistic revenue ranges.
