Announcing Psychosynth, the synthetic behavioral data marketplace built specifically for @base Agentic Finance. By serving literature-backed psychometric vectors—Big Five, Dark Triad, and Prospect Theory loss aversion curves—Psychosynth eliminates the risk-homogeneity bias of standard LLMs. This enables developers and quantitative funds to simulate realistic market participants, stress-test trading agents, and model counterparty risk under real market conditions. Economically and technically, Psychosynth operates as a zero-friction machine-to-machine marketplace on Base. Autonomous agents query datasets programmatically over HTTP without API keys, subscriptions, or human intermediaries. Every transaction settles query-by-query in USDC on Base mainnet via the x402 protocol using gasless EIP-3009 authorizations. Through @x402/extensions/bazaar metadata integration, every settled transaction automatically indexes Psychosynth into the Coinbase CDP Bazaar global catalog.
