Colombia NGV Fuel Prices — by Municipality

Turn Colombia's average compressed-natural-gas vehicle-fuel price dataset into clean, per-record local fuel economics - one row per municipality, date and fuel type with the average published price and municipality coordinates, ready for fleet buyers to compare local fuel costs.

Each source row becomes one clean, flat record with numeric fields coerced to real numbers, a stable source-native record_id, and provenance stamped on every row: source, resource id, the licence notice, the required attribution, a UTC retrieval timestamp and an interpretation caveat.

What one record represents

The source is he3q-86dn — Precios Promedio de Gas Natural Comprimido Vehicular (MinEnergia) on the Colombian national open-data portal (datos.gov.co). Each record is one average price for a municipality, date and fuel type: the price date (and year/month/day), the department and municipality, the fuel type, the average published price, the DANE municipality code and the municipality coordinates. The station commercial-name column is structurally excluded.

For each record you get a composite record_id built from the source-native key, the analytic columns listed below (reproduced verbatim, numbers as numbers), and the provenance block. Columns include fecha_precio (+ anio_precio/mes_precio/dia_precio), departamento_eds, municipio_eds, tipo_combustible, precio_promedio_publicado, codigo_municipio_dane and latitud_municipio/longitud_municipio.

Coverage and volume

The live dataset holds 10,975 municipality-date-fuel price records across Colombia - that is the record capacity of a full pull.

Live count: 10,975 records; the Wave-3 index figure of 10,971 was captured slightly earlier - the series grows as prices are published. This README states the difference; the capacity line is the live count.

The Actor pages the source with keyless SODA $query requests ordered by the source-native key for a stable total order, and stops as soon as your Maximum records cap is met. The station commercial-name column (nombre_comercial_eds) is never selected; coordinates are municipality-level, not station-level.

Licence and attribution

This dataset is published by Colombia's Ministry of Mines and Energy under Creative Commons Attribution-ShareAlike 4.0 (CC BY-SA 4.0). It is redistributed unchanged with attribution; the ShareAlike term applies to any redistributed database. The full notice travels on every record:

Colombia MinEnergia (datos.gov.co), CC BY-SA 4.0. Reproduced unchanged with attribution; ShareAlike applies to any redistributed database. No station operator/owner/representative name (nombre_comercial_eds) column is read or delivered.

The required attribution — Ministerio de Minas y Energia - MinEnergia, Bogota D.C. — travels on every record.

Interpretation caveat

Average published compressed-natural-gas vehicle-fuel (GNCV) price by municipality, date and fuel type. Prices are averages, not station-specific or transactional. Coordinates are municipality centroids, not station locations.

Values are reproduced verbatim: the Actor never rescales, re-derives or editorialises a number.

Person-data policy

The station operator/owner/commercial-name column (nombre_comercial_eds) is structurally excluded - never selected, never delivered, enforced by a never-in-SELECT allow-list and a planted-name test. Date, municipality, fuel type, price and municipality coordinates remain. This is a fuel-price product about places, not people.

Data quality and freshness

Numeric fields are coerced from the source's string encoding into real numbers (integers where whole, floats otherwise); genuinely missing cells are delivered as null, never as zero. Text is passed through verbatim. Every run re-reads the live source, so the data is as fresh as the portal itself, and each record's observed_at stamp records exactly when the row was retrieved. Delivery order is fixed by the source-native key, so a capped sample and a later full pull agree on their overlap and a repeated run returns rows in the same order. The RUN_RECEIPT reports source rows scanned and records delivered and charged for a per-run reconciliation.

Provenance, licensing and compliance

Every run begins with a live source-preflight: the Actor reads the exact host's robots.txt at runtime and refuses to proceed if the crawl policy disallows the data path. The gate result — URL, HTTP status, byte length and a SHA-256 of the policy — is written to the run's RUN_RECEIPT, so each run carries its own audit trail. The Actor identifies itself with a transparent, non-impersonating User-Agent and never bypasses a block, solves a challenge, or fetches through a cache or mirror. When the door is genuinely unavailable the run fails loudly and bills nothing.

Inputs

• Maximum records (maxRecords) — hard cap on records delivered and billed. Raise it to pull the full set; lower it to sample cheaply. Records arrive in a stable, source-native order.

Output

Records land in the Actor's default dataset and export as JSON, CSV, Excel or via the Apify API. A tabular overview view surfaces the most useful columns for quick inspection while the full record retains every selected field and provenance stamp.

Fields in detail

The record leads with record_id — a stable composite key drawn from the source's own grain — followed by the analytic columns described above and closed by a provenance block: source, source_dataset (the Socrata resource id), licence, attribution, caveat and observed_at. Every one of those provenance fields is present on every record, so a single row is self-describing: hand it to a colleague or a downstream system and it carries its own origin, licence and retrieval time without reference back to this page. Because delivery is ordered by the source-native key, the same record always carries the same record_id across runs, which makes the dataset safe to diff, deduplicate, or upsert into a warehouse. Nothing in the record is computed or inferred beyond the explicit count where one is stated — every other value is the source's own, reproduced byte-for-byte.

Sibling Actors

This Actor draws on the same Colombian open-data portal as the fleet's co-tourism-registry-records cell (the National Tourism Registry) - the same door, a different dataset and a different job (fuel prices versus lodging registry). This Actor also shares its engineering — the runtime robots gate, push-then-charge billing and verbatim-value discipline — with the fleet's other public-data records Actors.

Pricing

This Actor uses Apify's pay-per-event model: a flat $0.05 per record actually delivered to the dataset, and nothing else — no monthly rental, no per-run base fee, no compute charge. Deliver 40 records and you pay $2.00; deliver 10,000 and you pay $500.00. Billing is wired after delivery — each record is pushed first and only then does the per-record event fire — so a mid-run failure can only ever under-charge you, never over-charge. Use Maximum records to cap spend precisely.

Scaling and limits

Set Maximum records low to sample the leading slice cheaply, or high to pull the full set. The Actor paginates server-side and delivers incrementally, so memory stays flat regardless of how many records you request, and you are billed only for what is actually delivered. Because the source is a live public API, extremely deep pagination is ultimately bounded by the source's own paging behaviour; for the vast majority of uses — sampling, a full refresh, or a scheduled top-up — the default paging is more than sufficient. Schedule the Actor on Apify to keep a downstream table current: each run re-reads the live source and re-stamps observed_at, so a nightly or weekly run gives you a dated, reproducible snapshot.

Typical uses

Compare local NGV fuel prices by municipality and date; track fuel-price trends over time; map price geography with the municipality coordinates; benchmark fleet fuel costs across Colombian regions; or feed a fleet-cost or logistics model with clean local fuel-price records.

What this Actor does not do

It does not forecast or model, does not merge multiple source tables into one record, and it never reads or delivers the station operator/owner name column. It gives you faithful, analysis-ready records — with a provenance trail you can audit on every run.
