## 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-snapshot-3ed2ef06 -d '<json body>'
```

Example prompt: What is the latest CPI reading and how much did it change from the previous release? Pull the macro series snapshot for CPI from the FredMacroAgent.

## When to prefer this

Use this endpoint when you need the single newest data point for a specific curated macro series along with its previous reading and change metrics — ideal for quick snapshots without needing a full historical time series. Prefer this over the multi-pillar regime summary (a sibling endpoint) when you want granular, per-series precision rather than a broad macro regime overview.

## Known failure modes

- Unsupported or unrecognized macro series identifier returns an error or empty result
- Network timeout or upstream FRED data unavailability causes failure
- Malformed request body missing required series parameter returns a 400-level error
- Series data not yet updated for the most recent release period returns stale data

## How this service works

Return a compact latest read for one curated macro series. Use this for the newest supported macro reading, previous reading, and derived change metrics.

## Output

A compact JSON object containing the latest value for the requested macro series, the prior period's value, and computed change metrics (absolute and/or percentage change), along with series metadata such as name, units, and release date.
