Current support

FelixFusion’s public API is designed around market-specific data surfaces. Market selection is typically expressed through dataset ids, source filters, and route parameters such as isos. The currently documented market with active dataset coverage is:

ercot

ERCOT dataset coverage

The public API exposes ERCOT data through the dataset catalog and query routes. Key ERCOT dataset families include:

Dataset family	Example dataset ids	Purpose
System load	`ercot_load`, `ercot_net_load`	Total load and net-load analysis
Fuel mix	`ercot_fuel_mix`	Generation by fuel type
Capacity and supply	`ercot_capacity_forecast`, `ercot_available_seasonal_capacity_forecast`	Capacity outlook and supply headroom
Storage	`ercot_energy_storage_resources`	Charging, discharging, and net output
Real-time pricing	`ercot_lmp_real_time_5_min`, `ercot_lmp_latest_by_settlement_point`	LMP analysis across locations
Day-ahead pricing	`ercot_settlement_point_price_day_ahead_hourly`	Day-ahead pricing surfaces
DART and pricing summary	`ercot_lmp_dart_5_min`	Day-ahead versus real-time spreads
Constraints	`ercot_binding_constraints_real_time_5_min`, `ercot_binding_constraints_recent`	Transmission constraint awareness
Conditions and status	`ercot_current_conditions`, `ercot_real_time_system_conditions`, `ercot_prc`	Operational state and alerts
Standardized views	`ercot_standardized_5_min`, `ercot_standardized_hourly`	Curated dashboard-ready unified views

Use the catalog endpoint to list all current ERCOT datasets:

curl -H "x-api-key: YOUR_API_KEY" \
  "https://api.felixfusion.ai/v1/datasets?source=ercot"

Query a specific ERCOT dataset

curl -H "x-api-key: YOUR_API_KEY" \
  "https://api.felixfusion.ai/v1/datasets/ercot_load/query?start_time=2026-05-18T00:00:00Z&end_time=2026-05-18T06:00:00Z"

Pricing locations for ERCOT

ERCOT pricing-location examples use the isos=ercot filter:

curl -H "x-api-key: YOUR_API_KEY" \
  "https://api.felixfusion.ai/v1/pricing_locations?isos=ercot"

Source of truth

The backend repository’s dataset inventory and materialized-view docs remain the source of truth for detailed dataset coverage and view design.
