## Methodology

Assembled programmatically from the live index: every entry is a Published, quality-gated listing in AI rank tracking carrying the "API" tag, ranked by tier then name. The numbers (6 tools, 100% with an API, paid plans $15.60–$79) are computed from the structured facts on those listings — this page exists only because the underlying data clears the density gate.
