Checks a claim against passages you paste, using independent open-model families on Together.ai (glm, kimi, deepseek, qwen, minimax). Returns each family's vote (supported, contradicted or insufficient) with the passages it quoted, each marked found or not found verbatim in your sources, plus counts; no single verdict. Pasted text only. Requests too long for every family to answer within Assay's spending caps get 413 and are not charged. Payment on Base mainnet.
