# ADH US Macro Signals — agentdatum.com

> ADH US Macro Signals — agentdatum.com is a paid API for AI agents from agentdatum.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-17).

Returns computed US macroeconomic signals (log-return momentum, volatility, z-score, percentile rank) derived from FRED and other macro data sources, normalized and timestamped for AI agent consumption.

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 adh-us-macro-signals-agentdatum-com-95c664bb
```

Example prompt: Pull the latest US macro signals from ADH — I need the momentum, volatility, z-score, and percentile rank for the GDP series so I can assess the current macro regime.

## When to prefer this

Choose this endpoint when your agent needs pre-computed, normalized US macroeconomic signals (momentum, volatility, z-score, percentile rank) rather than raw economic data — it aggregates 239 sources, resolves entities, and time-syncs series so your agent gets analysis-ready intelligence without doing its own signal computation. Prefer it over raw FRED API calls when you need regime context, cross-series comparability, or derived conclusions baked in.

## Known failure modes

- Payment not settled via x402 — returns 402 Payment Required
- Upstream FRED or data source temporarily unavailable — may return stale or partial data
- Series with insufficient history returns zeros for computed metrics (zscore_10=0, pctrank_10=0)
- Invalid or missing x402 payment header — request rejected before processing

## Output

A JSON object containing an array of macro signal records, each with: series ID (e.g. econ-fred__GDP), status, number of data points, most recent value, log-return over 1 period, 4-period momentum, 20-period volatility, 10- and 30-period z-scores, 10- and 30-period percentile ranks, and a history array of {timestamp, value} pairs. Also includes source, data_type, and collection/generation timestamps.
