The full upstream README, mirrored here for reference. Install config, tool schemas, adoption signals, and an original overview live on the Macro Pulse X402 listing page.
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.
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.
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:
NETWORK=eip155:84532) — what this is configured
for right now. Safe to test with fake USDC, $0 real risk.NETWORK=eip155:8453) — real money. For mainnet settlement
you need a facilitator that supports it. The public
https://x402.org/facilitator is 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/x402 manifest for auto-discovery.
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.
