VERDICT

Should I use Vaquill AI?

The most complete US primary law API. 5M+ sections across all 53 US jurisdictions via REST, MCP or SQL. - vaquill.ai

Depends. Buy if you are building software or AI workflows that need cheap, self-serve, licensed US primary-law data. Skip if you need case law, secondary sources, or a turnkey research product for lawyers.

Confidence

Medium. Based on ~40 public sources; most review and pricing items are Vaquill's own blog, so independent validation is limited.
