# NREL Alternative Fuels Station Locator (via 2s.io)

> NREL Alternative Fuels Station Locator (via 2s.io) is a paid API for AI agents from 2s.io, paid per call via x402, $0.0012/call, status unknown (last checked 2026-09-14).

Search and filter US alternative-fuel stations (EV, CNG, hydrogen, biodiesel, etc.) by location, fuel type, status, and access code using NREL AFDC data.

## Facts

- Endpoint: GET https://2s.io/api/energy/fuel-stations
- Price: $0.0012/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/nrel-alternative-fuels-station-locator-via-2s-io-c0d3731c
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_8HoN3NbaRJS6yY0Fqny2Z

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 nrel-alternative-fuels-station-locator-via-2s-io-c0d3731c
```

Example prompt: Can you find all available public EV charging stations within 15 miles of coordinates 37.7749, -122.4194, and show me what connector types and charger levels they offer?

## When to prefer this

Use this endpoint when you need authoritative, government-sourced data on US alternative-fuel station locations, especially for EV trip planning, fleet routing with CNG/LNG/hydrogen, or EV infrastructure analysis. Prefer this over consumer apps when you need structured programmatic access with rich filtering (fuel type, access, network, status) and precise geospatial queries.

## Known failure modes

- Missing location parameter (lat/lon, zip, or state required) — returns 400 or empty result
- Invalid fuel type code returns validation error
- Radius out of range (must be 0.1–500 miles) returns error
- No stations found in the specified area returns empty array
- Invalid state abbreviation returns no results
- EV network filter with non-existent network name returns empty results

## How this service works

Locate alternative-fuel stations across the US via NREL Alternative Fuels Data Center. Search by lat/lon + radius (miles), state, or zip. Filter by fuelType (BD=Biodiesel | CNG=Compressed Natural Gas | ELEC=Electric vehicle charging | E85=Ethanol | HY=Hydrogen | LNG=Liquefied Natural Gas | LPG=Propane | RD=Renewable Diesel), status (E=Available | P=Planned | T=Temporarily Unavailable), access (public/private), and EV network. For EV chargers, returns connector types (J1772, CHAdeMO, Tesla, etc.), Level 1/2/DC-fast counts, pricing, and access hours. Indispensable for trip-planning agents, fleet logistics, EV-adoption analysis.

## Output

Returns a list of alternative-fuel stations matching the query, each with name, address, fuel type, station status, access type, access hours, pricing, EV connector types (J1772, CHAdeMO, Tesla, CCS, etc.), Level 1/2/DC-fast charger counts, EV network affiliation, and geographic coordinates.
