Filter the NLR (formerly NREL) Alternative Fuel Stations API for NEVI-funded DC fast charging stations

Steps

1. Call GET https://developer.nlr.gov/api/alt-fuel-stations/v1 with fuel_type_code=ELEC to scope results to electric stations (the former developer.nrel.gov host was retired May 29, 2026 - update any old references; API keys carry over unchanged).
2. Add ev_charging_level filtering (e.g. dc_fast) to isolate DC fast chargers, since NEVI funding specifically targets DCFC corridor buildout rather than Level 2 stations.
3. Inspect each station record for its funding-source information to separate NEVI-funded stations from privately funded DCFC stations in the same result set.
4. Combine with a geographic filter (state, radius via the /v1/nearest endpoint, or the /v1/nearby-route endpoint for a driving route) to scope NEVI corridor coverage analysis to a specific highway or state buildout plan.
5. Cross-reference against the Alternative Fuels Data Center (afdc.energy.gov) published NEVI datasets when precision matters, since API funding classification can lag official program status updates.
