Gaspy NZ

Goal

Query live Gaspy NZ public crowd-sourced fuel price statistics through a small deterministic CLI with human-readable and JSON output, without browser automation, login, or price reporting.

Use this when

• A user specifically asks for Gaspy NZ or crowd-sourced/user-reported NZ fuel price data
• A user wants national observed Gaspy averages, minimums, maximums, and station counts by fuel type
• A user wants the public Gaspy top cheapest stations for 91
• A user wants Gaspy public activity metadata such as station count, brand count, Gas Spies, or recent confirmations
• A workflow needs a lightweight read-only Gaspy complement to official-source fuel price tools

Do not use this for

• Official retailer-published NZ fuel prices from Gull, Z, BP, or FuelClock; use fuelclock-nz for that official-source alternative
• Station lookup, nearby search, regional search, or station detail requests; those Gaspy mobile API surfaces require login and are intentionally not implemented here
• Updating, confirming, reporting, or correcting Gaspy prices
• Authenticated Gaspy account, favourites, notifications, leaderboards, Gaspy Gold, garage, or vehicle actions
• Historical or commercial Gaspy datasets; contact Datamine/Gaspy for licensed extracts

Preferred workflow

1. Run scripts/cli.py with the narrowest subcommand that answers the task
2. Use summary for a quick Gaspy public snapshot across prices, metadata, and top 91 stations
3. Use prices --fuel when the user asks about one fuel type
4. Use cheapest --fuel 91 only for the public top-cheapest 91 table
5. Use --json for agent chaining, comparisons, or structured reports
6. Mention that Gaspy data is crowd-sourced/user-reported and may be stale or wrong

CLI

Run with:

python3 skills/gaspy-nz/scripts/cli.py <command> [flags]

Commands

• summary [--json] - national observed price stats, feed metadata, and top cheapest 91
• prices [--fuel 91|95|98|100|diesel|lpg|type-21] [--json] - national observed price stats by fuel
• cheapest [--fuel 91] [--limit N] [--json] - public top cheapest stations for 91
• metadata [--json] - station count, brand count, Gas Spies, confirmations, and feed timestamps
• fuel-types [--json] - fuel type ids observed in the public feed

Examples:

python3 skills/gaspy-nz/scripts/cli.py summary
python3 skills/gaspy-nz/scripts/cli.py prices --fuel diesel --json
python3 skills/gaspy-nz/scripts/cli.py cheapest --fuel 91 --limit 3 --json
python3 skills/gaspy-nz/scripts/cli.py metadata --json
python3 skills/gaspy-nz/scripts/cli.py fuel-types --json

Resources

• CLI entrypoint: scripts/cli.py
• API and stability notes: references/api-notes.md

Notes

• No API key, username, password, account cookie, private token, or browser session is required for the implemented read-only operations
• Uses the public Firebase Realtime Database feed behind https://www.gaspy.nz/stats.html
• Python stdlib only; no package install required
• --json output is intended for chaining into other tools or agent steps
• Public Gaspy station/nearby mobile endpoints were checked and require login, so they are documented as out of scope rather than exposed as broken commands
• Gaspy prices are crowd-sourced observations; incorrect, discounted, stale, or missing station prices are possible
• fuelclock-nz remains the better tool when the user asks for official retailer-published prices or FuelClock supply/watch data
