DataSignals Lab reads official public sources (SEC EDGAR, openFDA, ClinicalTrials.gov, NIH RePORTER, USAspending, the US House Clerk, CoinGecko and the App Store) and publishes them as scored, ranked signals with a link back to every original document.

Free previews and a weekly digest, $19 one-off reports, $29/month for everything, an events API from $29/month for programmatic access to eleven filing streams, and MCP servers for AI agents. The daily signal set is hashed into an append-only chain anchored in Bitcoin, so the track record is auditable rather than asserted.
