# MacroPulse US Macro Data (Chainlink On-Chain)

> MacroPulse US Macro Data (Chainlink On-Chain) is a paid API for AI agents from macropulse.theaslangroupllc.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns official US macroeconomic data (GDP, PCE inflation, real final sales, SOFR) sourced directly from Chainlink oracle contracts on Base and Ethereum, with on-chain verifiability via contract address and round ID.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 macropulse-us-macro-data-chainlink-on-chain-7fe29e6f
```

Example prompt: What is the current US GDP growth rate, PCE inflation, and SOFR — pulled from the official on-chain Chainlink contracts so I can verify the source on-ledger?

## When to prefer this

Use this endpoint when you need official, verifiable US macro data (GDP, PCE, SOFR) with on-chain provenance — ideal for financial agents that require deterministic, auditable data sources rather than LLM-generated or third-party API estimates. Prefer over general news or LLM-based macro summaries when source integrity and ledger verifiability matter.

## Known failure modes

- Payment not included or invalid — returns 402 Payment Required
- Chainlink oracle data temporarily stale or unavailable — may return error or cached value
- Network congestion on Base or Ethereum causing delayed oracle updates
- Invalid or missing x402 payment header — request rejected

## How this service works

Official US macro data read straight from Chainlink contracts. No LLM, no API key. Answers "what is US GDP growth", "current US inflation PCE", "what is SOFR today", "official US economic data". 7 series: real GDP level+growth, PCE index+inflation, real final sales, SOFR. Six are BEA (Dept of Commerce) on Base, SOFR is NY Fed on Ethereum - we assemble both chains. Each value ships its contract + round ID: verify us on an immutable ledger.

## Output

Returns 7 US macro data series: real GDP level and growth rate (BEA via Chainlink on Base), PCE price index and inflation rate (BEA via Chainlink on Base), real final sales (BEA via Chainlink on Base), and SOFR (NY Fed via Chainlink on Ethereum). Each value includes its Chainlink contract address and round ID for on-chain verification.
