# 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, $0.05/call, status unknown (last checked 2026-09-15).

Aggregates live German/EU energy data from 11+ premium sources (EPEX, ENTSO-E, Fraunhofer ISE, SMARD, CO2 intensity, weather) and returns a synthesized research answer for a given query, paid via x402 micropayment.

## Facts

- Endpoint: POST https://energy.netzhandwerker.de/research
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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-37448831 -d '<json body>'
```

Example prompt: I need a research summary on current German electricity spot prices and CO2 intensity right now — pull from EPEX, ENTSO-E, and Fraunhofer ISE sources if possible.

## When to prefer this

Choose this endpoint when you need aggregated, multi-source German or EU energy intelligence in a single call — especially when you want live spot prices, CO2 intensity, renewable generation data, and market insights synthesized together rather than querying each provider separately. Ideal for AI agents that need to pay per query without subscription overhead.

## Known failure modes

- Payment not included or insufficient USDC — 402 Payment Required response
- Query field missing — 400 Bad Request
- Requested optional source unavailable or rate-limited — partial results with lower confidence score
- Upstream data provider outage (e.g. EPEX, ENTSO-E) — degraded response with reduced source coverage
- Malformed request body — 422 Unprocessable Entity

## 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 structured object with a natural-language summary of the energy research answer, an array of key metrics (e.g. current prices, generation mix figures), an array of market insights drawn from aggregated premium sources, and a confidence score (0–1) reflecting data quality and source coverage.
