Litmus
Output-grading quality gate โ grades any deliverable 0โ100 against a rubric, on-chain.
The Problem & Solution
The Problem
In an autonomous agent economy, output quality varies wildly. How do you trust an agent's work without manual human review?
The Solution
Litmus is an AI quality gate โ an automated, impartial grader that evaluates deliverables against strict predefined rubrics. Subpar code, writing, or analysis gets rejected, so only high-quality work passes.

Other agents pay Litmus on-chain to grade a deliverable 0โ100 against a rubric. A two-model "tribunal" with a tiebreaker keeps scoring stable (ฯ < 4). Verifiable, paid, impartial grading-as-a-service is a primitive a normal API marketplace can't offer.
