> Access real-time and intraday data from California's electricity grid (CAISO), including current demand and forecasts, generation supply mix, renewable energy levels, CO2 emissions and carbon intensity, locational marginal prices (LMPs), and overall grid operating status.

**Category:** Government & Public Data | **Website:** [caiso.com/](https://caiso.com/) | **Docs:** [parse.bot/marketplace/06859a14-7110-452a-8127-210ccfdb22b9/caiso-com-api](https://parse.bot/marketplace/06859a14-7110-452a-8127-210ccfdb22b9/caiso-com-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/caiso/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Get current demand

Fetch current and forecasted electricity demand from CAISO Today's Outlook. Returns current system demand, available capacity, reserves, and forecasted peak demand for today and tomorrow. All values in megawatts. Timestamp is Pacific time in YYYYMMDDHHmmSS format.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/caiso/get-current-demand \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### Get current emissions

Fetch current CO2 emissions and carbon intensity data from the CAISO grid. Returns total emissions rate in metric tons per hour, carbon intensity in metric tons per MWh, current demand, and renewables share.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/caiso/get-current-emissions \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### Get current supply

Retrieve the current supply mix breakdown by fuel type. Returns generation in MW for each fuel source (Solar, Wind, Nuclear, Natural Gas, Large Hydro, Imports, Batteries, Geothermal, Biomass, Biogas, Small Hydro, Coal, Solar Hybrids, Wind Hybrids), total renewables, and renewables percentage.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/caiso/get-current-supply \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### Get demand trend

Retrieve the 5-minute average system demand trend for the current day. Returns a time-series array with current demand, hour-ahead forecast, day-ahead forecast, and demand response values at each 5-minute interval. Values are strings representing MW.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/caiso/get-demand-trend \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### Get grid status

Retrieve current grid operating status and active emergency notices. Returns overall status (Normal, Alert Active, etc.), current and upcoming events, and current system demand in MW.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/caiso/get-grid-status \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### Get price map

Retrieve current Price Map data showing nodal Locational Marginal Prices (LMPs) across the CAISO grid. Returns price legend with color-coded ranges, node markers with coordinates, names, area, and price components (energy dp/de, congestion dc, loss dl) for day-ahead (d*), real-time 15-min (q*), and real-time 5-min (f*) markets.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/caiso/get-price-map \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```
