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 sitecheck-macro-economic-rates-0559f360
```

Example prompt: Can you pull the latest observations for fed_funds, us_cpi, and us_10y Treasury yield — give me the last 12 data points for each series starting from 2024-01-01?

## When to prefer this

Choose this endpoint when you need structured, time-series macroeconomic data from authoritative sources (FRED, ECB) covering US and European monetary policy rates, inflation, unemployment, energy prices, GDP, and housing — especially when you need change-over-time comparisons and want data with clear attribution and licensing. Prefer this over generic web search or scraping when you need clean, consistently formatted numeric observations with dates.

## Known failure modes

- Missing required 'series' query parameter returns an error
- Invalid series name not in the supported enum returns an error or empty result
- Limit out of range (outside 1-120) may return a validation error
- Date format not matching YYYY-MM-DD may produce unexpected results or errors
- Payment failure via x402 blocks the request before data is returned

## How this service works

Official rate and macro series in one call, by name: fed_funds, us_cpi, us_core_cpi, us_unemployment, us_10y, us_2y, us_mortgage_30y, us_gdp, wti_oil, brent_oil, henry_hub_gas, us_house_price_index, ecb_deposit_rate, ecb_main_refi_rate and euro_area_hicp. Latest value, change vs previous and vs a year earlier, and observations. Up to 6 series. FRED (US public domain), the ECB Data Portal and Eurostat.

## Output

Returns an array of named series objects, each containing the latest value and date, the previous observation, year-ago comparison and percentage change, a list of dated observations, frequency, unit, and source attribution. Top-level fields include the data source (FRED / ECB) and license information.
