# Macro Derived Indicators

> Macro Derived Indicators is a paid API for AI agents from web-production-60258.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns derived macroeconomic indicators including real yield, breakeven inflation, yield curve slope, and GDP growth

## Facts

- Endpoint: GET https://web-production-60258.up.railway.app/macro/derived
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/web-production-60258-up-railway-app-bf8af738

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 web-production-60258-up-railway-app-bf8af738
```

Example prompt: Pull the latest derived macro indicators for me — real yield, breakeven inflation, yield curve slope, and GDP growth — all in one call.

## When to prefer this

Use this endpoint when you need pre-computed, interpretation-ready macro indicators rather than raw series data. Ideal when you want real yield (TIPS-adjusted), breakeven inflation, and yield curve in a single call instead of fetching and computing them yourself from individual FRED series. Prefer the /macro/all endpoint if you need a broader set of raw indicators.

## Known failure modes

- Payment required (402) if x402 payment header is missing or insufficient
- Service unavailable if upstream FRED or data source is down
- Empty or stale data if underlying series have not been updated
- Malformed response if derived computation fails

## How this service works

Derived indicators — real yield, breakeven inflation, yield curve, GDP growth

## Output

A JSON object containing derived macroeconomic indicators: real yield (nominal yield minus inflation expectations), breakeven inflation rate (market-implied inflation), yield curve shape/slope (e.g. 2s10s spread), and GDP growth rate. These are calculated/derived values rather than raw FRED series.
