puriq-market-data

Real OHLCV hourly candles (BTC, ETH, SOL — 350 hourly rows each) for the PURIQ vertical's quant work: volatility estimation, abstention-gate calibration, backtests.

Provenance

Source: Coinbase Exchange public API (keyless fetch)
Ingest receipt: ingest-receipt.json — fetch time, per-asset row counts, data sha256
Rights: exchange market data; research/evaluation use. Not a licensed redistribution product.
Fail-closed: every fetch is receipted; stale data is refetched, never cached as fresh.

Why it exists

The estate's quant vertical (PURIQ) needs rights-labeled market data with provenance from birth. Every ingest writes a receipt to the chain. This is the honest version of a market-data feed: 350 hourly rows per asset, sha256-stamped.

Generated by the PURIQ ingest lane; receipt sha256: 805462ea6b667d91…
