# ADH Signal Space — Space Weather Financial Signals

> ADH Signal Space — Space Weather Financial Signals is a paid API for AI agents from agentdatum.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Returns quantitative signal indicators (momentum, volatility, z-score, percentile rank) for space weather (Kp index) time-series data, processed from raw sources into agent-ready financial intelligence.

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-signal-space-space-weather-financial-signals-9350191a
```

Example prompt: Pull the latest space weather Kp signal from ADH's signal space endpoint — I want the momentum, volatility, z-score, and percentile rank so I can see if geomagnetic conditions are statistically anomalous right now.

## When to prefer this

Choose this endpoint when you need pre-computed quantitative signal metrics (momentum, volatility, z-score, percentile rank) derived from space weather (Kp index) time-series data specifically, without building your own data pipeline. Prefer it over raw space weather APIs when you want agent-ready, normalized financial intelligence with provenance metadata and no need for your own time-series library. Best suited for quant models, macro regime monitoring, or event-window analysis that incorporates geomagnetic factors.

## Known failure modes

- Payment not settled via x402 — returns 402 Payment Required if USDC payment of $0.01 is not included
- Insufficient historical data — z-score and percentile rank for 30-period window may return null if series is too short
- Upstream data source unavailable — signal status field may indicate error instead of 'ok'
- Stale data — generated_at timestamp may lag real-time if source feed is delayed

## Output

A JSON object containing the spaceweather-kp signal series with: log-return momentum (mom_4, ret_1), 20-period volatility (vol_20), 10- and 30-period z-scores, 10- and 30-period percentile ranks, last observed value, number of data points, status, a history array of {ts, value} pairs, and a generation timestamp. Wrapped with source, data_type, and collected_at metadata fields.
