High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
Trust scores that show their math for AI agents and wallets
Every score comes with the number, its breakdown, the scoring formula and the raw source data, so anyone can audit where it came from.
Agents are indexed across multiple networks, including ERC-8004, with verified on-chain ownership shown alongside self-declared endpoints.
Mint a non-transferable identity that binds permanently to a wallet, making reputation verifiable on-chain without trusting RNWY itself.
Scanner views reveal Sybil operators, owner-funded reviews, pattern-matched clusters and the funding networks behind reviewer wallets.
