# GridHub Electricity Data – Latest Zone Snapshot

> GridHub Electricity Data – Latest Zone Snapshot is a paid API for AI agents from api.grid-hub.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-16).

Returns the most recent value of every published metric for a single electricity zone, including wholesale price, demand, interchange, generation mix, and carbon intensity with units and timestamps.

## 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 gridhub-electricity-data-latest-zone-snapshot-06273099
```

Example prompt: What are the latest electricity grid metrics for US-CAISO right now — price, demand, generation mix, everything they publish?

## When to prefer this

Use this endpoint when you need the single most recent snapshot of all available metrics for one electricity zone — ideal for real-time dashboards, alerts, or agent decisions based on current grid state. Prefer this over the historical endpoint when you only need current values, not a time series. Choose a different sibling endpoint if you need data across all 25 zones simultaneously or if you need historical data spanning days.

## Known failure modes

- Invalid zone ID returns an error; valid zone IDs must be from the supported enum list
- Payment failure (x402 protocol) returns 402 if USDC micropayment is not provided
- Upstream data source outage may result in stale or missing metric values
- Network timeout if the provider's data feed is temporarily unavailable

## How this service works

Most recent value of every metric one electricity zone publishes (wholesale price, demand, interchange; generation mix for GB and US-CAISO; carbon intensity for GB), each with unit and timestamp. Note European day-ahead prices can carry a timestamp up to ~36h ahead. Zone ids from /v1/zones.

## Output

A JSON object containing the most recent values of all metrics published for the requested electricity zone — including wholesale price (with unit and timestamp), demand, interchange, and where available generation mix (GB and US-CAISO) and carbon intensity (GB). European day-ahead prices may have timestamps up to ~36 hours ahead.
