# CAISO California ISO Grid Status (SiteCheck Trade & Energy)

> CAISO California ISO Grid Status (SiteCheck Trade & Energy) is a paid API for AI agents from api.tradeenergy-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).

Returns real-time CAISO California ISO grid data including 5-minute generation by source, current demand with forecasts, net load duck curve intervals, and today's solar/net load peaks.

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 caiso-california-iso-grid-status-sitecheck-trade-energy-e3f7755a
```

Example prompt: What's California's current grid generation mix right now — how much is coming from solar, wind, and natural gas, and what's the renewable share?

## When to prefer this

Use this endpoint when you need live or near-real-time California ISO grid generation data broken down by energy source, or when tracking the duck curve and net load, or when comparing current demand against official CAISO forecasts. Prefer this over generic energy APIs when CAISO-specific granularity by source type is required.

## Known failure modes

- CAISO Today's Outlook upstream unavailable or throttled — returns error
- No data yet for today if called very early in the day before CAISO publishes intervals
- Stale data if CAISO delays its 5-minute publication feed
- Network timeout on the Cloudflare Worker proxy layer

## How this service works

CAISO (California ISO) grid today, from its Today's Outlook data: latest 5-minute generation by source (solar, wind, geothermal, biomass, biogas, small and large hydro, coal, nuclear, natural gas, batteries, imports, other) in MW with renewable share, current demand with day-ahead and hour-ahead forecasts, net load (demand minus solar and wind — the duck curve) for every 5-minute interval so far, and today's peak solar and minimum net load.

## Output

Returns current 5-minute interval generation data by source (solar, wind, geothermal, biomass, biogas, small hydro, large hydro, coal, nuclear, natural gas, batteries, imports, other) in MW with renewable share percentage; current demand value alongside day-ahead and hour-ahead demand forecasts; net load (demand minus solar and wind) for all 5-minute intervals today forming the duck curve; and today's peak solar generation value and minimum net load.
