## Pricing

from $33.50 / 1,000 eia petroleum observations

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## 🛢️ US Petroleum Data API — EIA Crude, Fuel Prices & Stocks

Get US petroleum statistics as clean records — WTI and Brent spot prices, gasoline, diesel and heating-oil prices, crude and product stocks, refinery inputs and utilisation, imports, exports and field production — from the U.S. Energy Information Administration's official Open Data bulk file `PET.zip`.

Traders, fuel buyers, analysts and researchers use it to follow daily crude prices, weekly inventories and regional fuel prices without copying tables from EIA's site. EIA publishes 181,165 petroleum series in one 55 MB ZIP: this actor streams the file, keeps only the series you ask for and delivers one record per observation with units, frequency, period and area — no API key.

The unit of output is one observation (one series, one period). You pay per observation delivered; a run that finds nothing costs nothing.

### 📊 Sample Output

![Table of EIA petroleum observations: daily WTI Cushing spot prices in dollars per barrel.](https://api.apify.com/v2/key-value-stores/IXCaMKjxSmUTLHhmq/records/eia-petroleum-market-series-observations.png)

| series_id | period | value | units | series_name |
|---|---|---|---|---|
| PET.RWTC.D | 20260929 | 96.16 | Dollars per Barrel | Cushing, OK WTI Spot Price FOB, Daily |
| PET.RWTC.D | 20260928 | 99.37 | Dollars per Barrel | Cushing, OK WTI Spot Price FOB, Daily |
| PET.RWTC.D | 20260925 | 85.23 | Dollars per Barrel | Cushing, OK WTI Spot Price FOB, Daily |
| PET.RWTC.D | 20260924 | 95.88 | Dollars per Barrel | Cushing, OK WTI Spot Price FOB, Daily |
| PET.RWTC.D | 20260923 | 93.38 | Dollars per Barrel | Cushing, OK WTI Spot Price FOB, Daily |

Rows from live run `jVkkgPCFsdvexcj3E` on Apify (input: series PET.RWTC. and PET.RBRTE., since January 2026, 40 records). Notice the newest trading day first; the run fills its 40 records from WTI before reaching Brent, because series are read in file order.

### ✅ What you get

Every field of each record:

- `record_id` — `<series_id>:<period>`, unique per observation.
- `series_id` — EIA series id, e.g. `PET.RWTC.D`.
- `series_name` — series name as EIA publishes it.
- `units` — units, e.g. `Dollars per Barrel`.
- `units_short` — short units, when EIA gives them.
- `frequency` — `A`, `Q`, `M`, `W`, `D` or `4` (four-week average).
- `frequency_label` — annual, quarterly, monthly, weekly, daily, four-week average.
- `period` — period exactly as published: `2025`, `2025Q2`, `202506` or `20250613`.
- `period_start` — first day of the period as an ISO date.
- `value` — the observation. Only non-null observations are delivered.
- `geography` — EIA geography code(s), e.g. `USA-TX`.
- `geography2` — second geography for flows between two areas.
- `iso3166` — ISO 3166 code, when given.
- `latitude`, `longitude` — plant-level series only.
- `series_description` — EIA's description of the series, when given.
- `series_start`, `series_end`, `series_last_updated` — the series' first and last period, and when EIA last updated it.
- `source`, `source_dataset`, `licence`, `attribution`, `observed_at` — provenance on every record: EIA and the dataset, the bulk file and its last-modified date, EIA's public-domain statement quoted, the acknowledgment EIA asks for (e.g. `Source: U.S. Energy Information Administration (Sep 2026)`), and the UTC time the record was read.

### ⚙️ Sample inputs

**1. Store example — WTI and Brent spot prices**

```json
{
  "seriesIdPrefixes": ["PET.RWTC.", "PET.RBRTE."],
  "maxRecords": 10
}
```

The 10 newest daily WTI observations (the first matching series); about $0.50 on the Free plan.

**2. Narrowed — WTI and Brent daily since January 2026**

```json
{
  "seriesIdPrefixes": ["PET.RWTC.", "PET.RBRTE."],
  "frequencies": ["D"],
  "periodFrom": "2026-01",
  "maxRecords": 400

```json
{
  "seriesIdPrefixes": ["PET."],
  "frequencies": ["W"],
  "latestOnly": true,
  "maxRecords": 1500

### 🔧 How it works

1. **Robots check.** `www.eia.gov/robots.txt` is read on every run; it allows `/opendata/bulk/`. A real disallow stops the run with nothing charged.

2. **Streamed download.** The actor opens `https://www.eia.gov/opendata/bulk/PET.zip` and decompresses the ZIP line by line as it arrives. Nothing is saved to disk and the file is never downloaded first.

3. **Filter before parsing.** Each line is one series. Its id is checked against your prefixes, ids and frequencies before the line is parsed, so a narrow request skips most of the file. Name and geography filters parse every series line.

4. **Deliver, then charge.** Non-null observations inside your period window become records, newest first, pushed in batches; each batch is charged after delivery, so records and charges always match. The download stops the moment `maxRecords` or your maximum charge is reached.

5. **Receipt.** `RUN_RECEIPT` records the file and its date, lines read, series matched, whether the file was read to the end, and delivered and charged counts.

No login, API key, proxy or bot workaround — one public EIA file, and no personal data in it.

### 💰 Pricing example

Per observation delivered, no start fee, no monthly charge:

| Apify plan | Price per observation |
|---|---|
| Free | $0.05 |
| Bronze | $0.045 |
| Silver | $0.04 |
| Gold, Platinum, Diamond | $0.0335 |

- 10 observations (the Store example): $0.50 on the Free plan, $0.335 on Gold.
- 1,000 observations (the default cap): $50 on Free, $45 on Bronze, $40 on Silver, $33.50 on Gold.

**Coverage and size.** Live count from the file read on 3 October 2026 (PET.zip, last modified 2 October 2026): **13,868,123 non-null observations in 181,165 series** (plus 14,077 category lines = 195,242 lines; the planning index counted 195,242 series and 13,868,123 observations — the observation counts agree). The file is 55 MB compressed and 368 MB of text. A filter is required; a whole-file scan takes seconds, and a full pull is 13,868,123 records, billed per observation. Frequencies: annual 94,773 series, monthly 84,767, weekly 1,159, four-week average 435, daily 31.

### ⚖️ Legal & ToS

Data: U.S. Energy Information Administration, Open Data bulk download (`PET.zip`). EIA's copyright and reuse page says: "U.S. government publications are in the public domain and are not subject to copyright protection. You may use and/or distribute any of our data, files, databases, reports, graphs, charts, and other information products that are on our website or that you receive through our email distribution service." EIA asks for an acknowledgment with the publication date; every record carries one in `attribution`.

The actor reads only this public file with a declared User-Agent; `www.eia.gov/robots.txt` allows the path and is checked on every run. No login, key, proxy or form. Energy statistics and facility-level series only — no personal data.

This actor is not affiliated with or endorsed by EIA. Figures are EIA's as published in the file; check EIA's release notes for revisions.

### ❓ FAQ

**Do I need an EIA API key or account?**
No. The actor reads EIA's public bulk file, which needs no key, login or registration.

**Why must I give a series prefix, id, name or geography?**
Because the file is large (368 MB of text, 13.9 million observations). A filter keeps runs fast and bills only what you asked for; the actor refuses an unfiltered run with a clear message.

**Why did my run return 0 records?**
Nothing in the file matched — usually a prefix that is too specific or a period window with no data. The receipt shows how many series matched. A zero-record run is not charged.

**How fresh is the data?**
As fresh as EIA's `PET.zip`, which EIA republishes as its releases update; each record names the file's last-modified date.

**Can I get the whole file?**
Yes: widen the filters and raise `maxRecords`. The file is streamed, never held in memory; the receipt states how far it was read. Large pulls take a long time and are billed per observation.

**Where are the spot prices?**
Daily crude spot prices are `PET.RWTC.D` (WTI, Cushing) and `PET.RBRTE.D` (Brent, Europe); weekly and monthly versions end in `.W` and `.M`.

### 🆘 Troubleshooting

- **0 records** — check the id on EIA's site and that it starts with `PET.`; the period window may be empty.
- **Too many series matched** — add `frequencies` or a longer prefix.
- **Only one series returned** — the run stopped at `maxRecords`; raise it or use `latestOnly` to get one record per series.
- **CAPPED message** — your maximum total charge was reached; raise it in the run options.
