Negative results are worth money.
Nobody has ever paid for them.

Luqman is a pay-per-query knowledge marketplace for the research that never gets published — the failed experiments, the ruled-out compounds, the dead-end hyperparameters. AI agents pay a few cents per citation. Researchers finally get paid for what they actually learned.

The file-drawer problem

The most valuable knowledge
in science is the knowledge
nobody is allowed to sell.

Pharma, materials labs, and ML researchers all run thousands of experiments that don't work. A drug candidate that fails phase I. A fine-tune that collapses. A cathode formulation that degrades at 45°C. This is expensive, irreplaceable negative knowledge — and it sits on hard drives forever, because journals only publish wins.

Meanwhile, AI agents are scaling out to millions of autonomous research queries. They'd happily pay for a citation that saves their principal three months of replicating a dead end. But there's no rail for them to pay with — credit card APIs can't settle five cents, and Stripe can't split it 85/15 between a researcher and a platform per call.

Luqman builds that rail. Every retrieval is a sub-cent on-chain payment split deterministically between the researcher and the platform — settled in seconds on Circle's Arc testnet. Agents pay. Researchers earn. Knowledge flows.

Pricing

Three tiers of negative knowledge.

Every chunk has a price. Every retrieval pays the researcher 85%. The split is enforced in basis points with ROUND_DOWN rounding — platform picks up the crumb.
