Verifiable answers, at a fraction of the cost.

Your agent answers from the primary source — every figure traceable to the filing it came from, not guessed from increasingly AI-generated or SEO-optimized web pages.

And it's efficient: the same agent, with vs without MetricDuck on vals.ai's Finance-Agent v2 — ~½ the cost · ~⅓ the steps.

Cost per correct answer: $0.60 with MetricDuck vs $1.21 without — about half.
