# Die Netzhandwerker - Energy Research Hub

> Die Netzhandwerker - Energy Research Hub is a paid API for AI agents from energy.netzhandwerker.de, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Aggregates live German/EU energy data (spot prices, CO2 intensity, grid data, forecasts) from 11+ premium sources via a micropayment-gated research task API

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 die-netzhandwerker-energy-research-hub-7f500c61 -d '<json body>'
```

Example prompt: Can you research the current German electricity spot prices, CO2 grid intensity, and renewable generation mix right now — pulling from EPEX, ENTSO-E, and Fraunhofer ISE — and give me a summary? Use a $1.00 USDC bounty.

## When to prefer this

Choose this endpoint when you need live, multi-source German or EU energy market data aggregated from authoritative premium sources (EPEX, ENTSO-E, Fraunhofer ISE, SMARD) in a single call, especially when spot prices, CO2 intensity, and renewable generation data need to be cross-referenced. Ideal for AI agents that can execute x402 micropayments in USDC and need comprehensive German energy research rather than a single data point from a free API.

## Known failure modes

- Insufficient bounty amount (below $1.00 USDC minimum) — task rejected
- Missing task_description field — validation error
- Payment not processed via x402 protocol — 402 Payment Required response
- Upstream data source unavailable (e.g. EPEX or ENTSO-E outage) — partial or degraded results
- Malformed USDC bounty string — parsing error

## How this service works

Live electricity prices, carbon intensity, grid load, renewable share, flexibility windows, battery arbitrage, trading signals and ESG reporting for autonomous agents.

## Output

Returns a task ID and status confirming the energy research task has been accepted; the aggregated results from 11+ premium sources (EPEX spot prices, ENTSO-E day-ahead, CO2 intensity, Fraunhofer ISE generation data, SMARD, GruenstromIndex, weather forecasts) are delivered asynchronously or synchronously depending on task complexity.
