SimpleFunctions exports two kinds of historical state so you can reproduce research without scraping rendered pages or hitting the public API every loop.

Live state right nowThe real-time data API at data.simplefunctions.dev/v1.
Historical state, offline, batchThe public HuggingFace datasets below.

​
Public HuggingFace datasets

All five datasets live under the SimpleFunctions organization. They are public — git clone and huggingface-cli download work without auth.
DatasetContentsCadenceFiles
SimpleFunctions/sf-index-historySimpleFunctions Index time series across themes.Dailysf-index-history.jsonl
SimpleFunctions/world-state-dailyCompact daily world snapshot — top markets, regime distribution, tail-risk roll-up.DailyYYYY-MM-DD.json
SimpleFunctions/world-awareness-benchQuestion / answer pairs measuring whether a model “knows the world”.Periodicbenchmark_YYYY-MM-DD.json
SimpleFunctions/settled-marketsResolved markets with terminal state — for calibration and backtesting.MonthlyYYYY-MM.jsonl
SimpleFunctions/calibration-scorecardsScoring of public theses and forecasts against settled outcomes.MonthlyYYYY-MM.json

​
Use from datasets

from datasets import load_dataset
ds = load_dataset("SimpleFunctions/sf-index-history")

Live snapshots

For current state, hit the realtime data API: 
curl "https://data.simplefunctions.dev/v1/snapshot"
curl "https://data.simplefunctions.dev/v1/markets/featured?n=20"
See Real-time data for response shapes, WebSocket topics, and rate limits.

​
Provenance

Public exports include enough timestamp and source metadata to reconstruct the state that produced a public chart, answer, or backtest. Where a row carries a trace id, treat it as a support / audit handle, not as a public database schema. See Provenance.

​
What is not exported

Internal storage, raw cron output, observability tables, and unsettled in-flight intents are not part of any public export. If you need a slice that is not on HuggingFace, open an issue or email patrick@simplefunctions.dev rather than assuming an internal path.
