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 heurist-mesh-fredmacroagent-macro-series-history-61ac91ad -d '<json body>'
```

Example prompt: Pull the historical series for US CPI from January 2015 through December 2024 using a year-over-year transformation so I can see how inflation has trended over the past decade.

## When to prefer this

Choose this endpoint when you need bounded historical data for a specific FRED macro series — especially when you want pre-computed transformations like YoY or qoq_annualized rather than raw values. Prefer this over the macro regime summary endpoint when you need granular time-series data for a single indicator rather than a multi-pillar snapshot.

## Known failure modes

- Invalid or unsupported macro series identifier returns an error
- Date range out of bounds for the requested series returns empty or partial data
- Unsupported transformation type returns an error
- Payment failure ($0.003 USDC) blocks request execution
- Network timeout for large historical ranges

## How this service works

Return bounded history for one curated macro series. Use this for historical trend analysis or transformed views like YoY or qoq_annualized.

## Output

A time-indexed array of data points for the requested macro series within the specified date bounds, optionally transformed into YoY percentage changes or quarter-over-quarter annualized rates. Each observation includes the date and corresponding value.
