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 netzhandwerker-energy-research-hub-heating-bundle-5fcc6374 -d '<json body>'
```

Example prompt: Pull the current electricity prices, carbon intensity, and flexibility windows for my heating system in Germany so I can decide whether to run my heat pump now or wait for a cheaper, greener window later today.

## When to prefer this

Choose this endpoint when you need a comprehensive, bundled snapshot of energy market conditions specifically relevant to heating decisions — combining price, carbon, flexibility, and ESG data in a single call rather than querying multiple separate endpoints.

## Known failure modes

- Region or zone not supported — 404 or empty dataset returned
- Grid data provider unavailable — 503 service unavailable
- Invalid request body or missing required fields — 400 bad request
- Payment not processed or insufficient funds — 402 payment required
- Rate limit exceeded — 429 too many requests

## 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

A bundle of real-time energy data including spot electricity prices, grid carbon intensity, current grid load, renewable energy share, identified flexibility/arbitrage windows, battery charge/discharge signals, and ESG metrics — all scoped to heating applications.
