## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/parse-caiso-com-api-06859a14/`
**Auth:** `Authorization: Bearer <LOCUS_API_KEY>`

## 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/parse-caiso-com-api-06859a14/get_current_demand \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -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/parse-caiso-com-api-06859a14/get_current_emissions \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -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/parse-caiso-com-api-06859a14/get_current_supply \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -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/parse-caiso-com-api-06859a14/get_demand_trend \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -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/parse-caiso-com-api-06859a14/get_grid_status \

  -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/parse-caiso-com-api-06859a14/get_price_map \
