# ADH European Electricity Price Signal

> ADH European Electricity Price Signal is a paid API for AI agents from agentdatum.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Returns quantitative momentum, volatility, z-score, and percentile-rank signals for European electricity prices derived from a multi-source financial intelligence layer.

## 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 adh-european-electricity-price-signal-12c28b21
```

Example prompt: Pull the latest European electricity price signal — I need the momentum, volatility, z-score, and percentile rank so I can see whether EU power prices are historically cheap or expensive right now.

## When to prefer this

Choose this endpoint when you need pre-computed, statistically normalized signals (z-score, percentile rank, momentum, volatility) for European electricity prices rather than raw price data alone. It is particularly valuable for regime detection, mean-reversion analysis, and feeding quantitative context into AI agents or macro models without building your own signal computation pipeline.

## Known failure modes

- Payment not settled via x402 — returns 402 Payment Required
- Data source temporarily unavailable — status field may indicate error
- Stale data if upstream feeds are delayed — check generated_at timestamp
- Invalid or missing required input parameters — returns 400 Bad Request
