Key Differences
Quiver is broad. Zhane is deep.
Quiver aggregates dozens of alternative data sources - congressional trades, lobbying, government contracts, Reddit sentiment. Zhane does one thing: parse SEC 8-K filings in real time and tell you exactly what material event occurred, how urgent it is, what the dollar figures are, and what the filing says. If 8-K signal intelligence is your use case, deeper beats broader.
Real-time vs. aggregated
Quiver's 8-K data typically lags by hours to days due to ETL normalization. Zhane hits the SEC EDGAR ATOM feed live - no database intermediary, no batch jobs. Your script can be running on a signal before Quiver's pipeline has even seen it.
Urgency scoring is the key differentiator
Neither Bloomberg nor Quiver tells you "this 8-K is CRITICAL because Item 4.02 (non-reliance on financial statements) was filed." Zhane bakes it in: every filing gets an urgency score, and /v1/signals returns only the ones worth your attention.
Use both if you can
Quiver is excellent for congressional trading signals and government contract flows. Zhane is purpose-built for 8-K event-driven strategies. At $29/mo, cheap enough to run alongside Quiver without budget impact.
