# GridHub Map Snapshot – All Zones

> GridHub Map Snapshot – All Zones is a paid API for AI agents from api.grid-hub.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Returns current electricity price, demand, and carbon intensity for all 25 GridHub zones in a single call, refreshed every 5 minutes.

## Facts

- Endpoint: GET https://api.grid-hub.app/v1/map/snapshot
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/gridhub-map-snapshot-all-zones-e35c88be
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_uG-rVqyuqyJcTh3lN2oOv

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 gridhub-map-snapshot-all-zones-e35c88be
```

Example prompt: Pull the latest GridHub snapshot and tell me which of the 25 zones has the cheapest wholesale electricity price and the lowest carbon intensity right now.

## When to prefer this

Use this endpoint when you need to compare or rank multiple electricity zones simultaneously in a single call. If you only need data for one specific zone with additional context, use /v1/brief/{zone} instead. This endpoint is ideal for dashboards, cross-zone optimization decisions, or any workflow that needs to evaluate all 25 zones at once without making 25 separate requests.

## Known failure modes

- Data temporarily unavailable if GridHub's 5-minute rebuild cycle is interrupted
- Individual zones may omit carbon intensity if the zone does not publish that metric
- Payment failure (x402) if USDC balance is insufficient or wallet is not configured
- Rate limiting if the endpoint is called too frequently within a short window

## How this service works

Current headline values (price, demand, and where published carbon intensity) for all 25 GridHub zones in one call. Use to compare or rank grids right now; rebuilt every 5 minutes. For one zone with context use /v1/brief/{zone}.

## Output

A JSON array covering all 25 GridHub zones, each entry containing the current wholesale electricity price, demand level, and (where published) carbon intensity value, with data no older than 5 minutes.
