|
|
| This repo mirrors the read-only data exposed by [CalcFi](https://calcfi.app) so it can be consumed as a Frictionless Data Package, mirrored to dataset registries, and version-controlled with full git history. |
|
|
| ## What's in here |
|
|
| 34 series across 11 categories, each in its own subdir under [`datasets/`](datasets/): |
|
|
| | Category | Series | |
| |---|---| |
| | Mortgage rates | 30-year-fixed, 15-year-fixed, 10-year-treasury | |
| | Interest rates | federal-funds-rate, prime-rate, 2-year-treasury | |
| | Inflation | cpi, pce | |
| | Employment | unemployment-rate, labor-force-participation, avg-hourly-earnings | |
| | Energy | crude-oil-wti, crude-oil-brent, us-regular-gas-price | |
| | FX | usd-eur, usd-gbp, usd-jpy | |
| | Crypto | bitcoin, ethereum, solana | |
| | Deposit rates | savings-national-rate, money-market-national-rate, cd-3mo, cd-12mo, cd-60mo | |
| | Credit | credit-card-apr, auto-loan-rate-48mo, personal-loan-rate-24mo | |
| | Commodities | copper-price, corn-price | |
| | Global (World Bank) | us-gdp-per-capita, world-inflation, world-unemployment, eurozone-gdp-per-capita | |
|
|
| Every subdir contains: |
|
|
| - `data.csv` — full history (date, value, unit), provenance headers preserved |
| - `datapackage.json` — [Frictionless Data Package](https://frictionlessdata.io/) descriptor, DataHub-compatible |
| - `README.md` — series-specific source, license, citation, and CalcFi live URL |
|
|
| ## Quick start |
|
|
| ```bash |
| # Full mortgage rate history |
| curl https://raw.githubusercontent.com/jerehere/calcfi-open-data/main/datasets/30-year-fixed/data.csv |
| |
| # CPI history |
| curl https://raw.githubusercontent.com/jerehere/calcfi-open-data/main/datasets/cpi/data.csv |
| |
| # Latest single value (live API, daily-refreshed) |
| curl https://calcfi.app/api/rates/30-year-fixed |
| ``` |
|
|
| ```python |
| import pandas as pd |
| url = "https://raw.githubusercontent.com/jerehere/calcfi-open-data/main/datasets/30-year-fixed/data.csv" |
| df = pd.read_csv(url, comment="#", parse_dates=["date"]) |
| print(df.tail()) |
| ``` |
|
|
| ```r |
| library(readr) |
| df <- read_csv("https://raw.githubusercontent.com/jerehere/calcfi-open-data/main/datasets/30-year-fixed/data.csv", |
| comment = "#") |
| ``` |
|
|
| ## Primary sources |
|
|
| All values pass through verbatim from these official sources. No transformations or imputations are applied. |
|
|
| - [**FRED**](https://fred.stlouisfed.org/) — Federal Reserve Economic Data (St. Louis Fed) |
| - [**Freddie Mac PMMS**](https://www.freddiemac.com/pmms) — Primary Mortgage Market Survey |
| - [**BLS**](https://www.bls.gov/) — Bureau of Labor Statistics (CPI, employment, wages) |
| - [**BEA**](https://www.bea.gov/) — Bureau of Economic Analysis (PCE) |
| - [**US Treasury**](https://home.treasury.gov/) — Treasury yields |
| - [**FDIC**](https://www.fdic.gov/resources/bankers/national-rates/) — National Rates and Rate Caps |
| - [**EIA**](https://www.eia.gov/) — Energy Information Administration (oil, gas) |
| - [**Federal Reserve H.10**](https://www.federalreserve.gov/releases/h10/) — Foreign exchange rates |
| - [**CoinGecko**](https://www.coingecko.com/) — Cryptocurrency spot prices |

| - [**IMF Commodity Data**](https://www.imf.org/external/np/res/commod/index.aspx) — Copper, corn (via FRED) |
|
|
| ## Refresh cadence |
|
|
| A GitHub Actions workflow ([`.github/workflows/refresh.yml`](.github/workflows/refresh.yml)) runs daily at 06:00 UTC, pulls the latest history from CalcFi's read-only API, and commits any changes. Most series update at their natural cadence: |
|
|
| - Daily: Treasury yields, FX, oil, crypto, fed funds |
| - Weekly: 30Y / 15Y mortgage, gas price |
| - Monthly: CPI, PCE, unemployment, hourly earnings, commodities |
| - Quarterly: credit card APR, personal loan |
| - Annual: World Bank series |

|
| This repository's structure, scripts, and README are released under [CC0 1.0](https://creativecommons.org/publicdomain/zero/1.0/). The data itself in `datasets/*/data.csv` is licensed [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/) — attribution requested. |

| **How to attribute:** |

|
| > Data via [CalcFi](https://calcfi.app), sourced from [primary source]. CC BY 4.0. |

| Primary source terms also apply where data is mirrored from FRED, BLS, World Bank, etc. — consult the per-dataset `README.md` for the canonical source link. |
|
|
| ## Why this exists |
|
|
| Most personal-finance and macro data APIs are paid, rate-limited behind a credit card, or wrap a single primary source you could hit yourself. [CalcFi](https://calcfi.app) is a free personal-finance calculator platform that consumes these primary sources for its tools; this repo exposes the same data as a clean, version-controlled, Frictionless-compliant dataset bundle so it can be mirrored to DataHub, Hugging Face, Kaggle, and Zenodo. |

| ## Mirroring this to other registries |
|
|
| This repo is structured so each subdir under `datasets/` is a complete Frictionless Data Package. To publish on DataHub.io, point at this repo and set "Root Dir" to e.g. `datasets/30-year-fixed`. Repeat per dataset. |
