# Heurist Mesh FredMacroAgent - Macro Series History

> Heurist Mesh FredMacroAgent - Macro Series History is a paid API for AI agents from mesh.heurist.xyz, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Returns bounded historical data for a curated macroeconomic time series, with support for transformed views such as year-over-year or quarter-over-quarter annualized changes.

## Facts

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-b0fbd7ba -d '<json body>'
```

Example prompt: Pull the historical CPI series from FredMacroAgent for the last 3 years and show me the year-over-year transformation so I can see how inflation has trended.

## When to prefer this

Use this endpoint when you need bounded historical data for a specific curated macroeconomic indicator and want transformed views (YoY, qoq_annualized) pre-computed rather than computing them yourself. Prefer this over the macro regime summary endpoint when you need raw or transformed time series data points rather than a synthesized narrative. Best for trend analysis, charting, and quantitative modeling of individual macro indicators.

## Known failure modes

- Unknown or unsupported series identifier returns an error or empty result
- Date range bounds outside available data coverage return partial or empty results
- Invalid transformation type string causes a bad request error
- Payment not settled via x402 protocol returns 402 Payment Required
- Upstream FRED data source temporarily unavailable causes 503 or timeout

## 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

Returns a time-bounded array of historical data points for the requested macro series, including timestamps and values. If a transformation (e.g. YoY, qoq_annualized) is requested, returns the computed transformed values alongside or instead of raw values. May include series metadata such as units and frequency.
