FilingFirehose vs Quiver Quantitative

Quiver aggregates alt-data on top of SEC filings (insider trades, lobbying, etc.). FilingFirehose is a focused SEC-filings API, not an alt-data aggregator.

When FilingFirehose is the right call

You want body-text-parsed 8-K items — including a flag for filings where the body language suggests a different item than what the filer reported. You're at the $29–$299/mo tier and don't need enterprise contracting.

When Quiver Quantitative is the right call

You want a much broader form-type catalog beyond the 8-K / S-3 / 13D core, you're willing to pay enterprise pricing, and brand recognition matters for an internal tooling pitch.
