How this ranking works. Each vendor's Agentic Index coverage score is the sum of its verified feature scores across the 14 buyer facing capabilities in the Agentic Index taxonomy, researched from public sources. Full support counts 1.0, partial support counts 0.5, and ties are broken alphabetically. A low score means less documented coverage in public materials, not a definitive absence of capability. The buyer need block above is computed from the same scores, taking the subset of criteria each need depends on. No vendor pays for placement.
