A domain-curated, license-verified metadata pointer index over computational fluid dynamics (CFD) datasets, papers, and code repositories harvested from DataCite, arXiv, CORE, OpenAlex, Zenodo, and GitHub. Every record returned has been confirmed redistribution_allowed at harvest time -- this is the falsifiable guarantee the listing sells, not raw data volume. Metadata pointers only -- no underlying datasets, papers, or code is downloaded or resold.

A domain-curated, license-verified metadata pointer index over general scientific machine learning (SciML) datasets, papers, models, and code harvested from arXiv, CORE, DataCite, OpenAlex, Zenodo, Hugging Face, and GitHub. Every record returned has been confirmed redistribution_allowed at harvest time -- this is the falsifiable guarantee the listing sells, not raw data volume. Metadata pointers only -- no underlying datasets, papers, models, or code is downloaded or resold.

A domain-curated, license-verified metadata pointer index over physics-informed neural network (PINN) datasets, papers, and models harvested from DataCite, arXiv, CORE, OpenAlex, and Hugging Face. Every record returned has been confirmed redistribution_allowed at harvest time -- this is the falsifiable guarantee the listing sells, not raw data volume. Metadata pointers only -- no underlying datasets, papers, or model weights are downloaded or resold.

Reviews Polymathica's governed experiment memory and returns advisory dream candidates, review decisions, and solver/PINN recommendations without running solvers, mutating registries, exposing raw source runs, or applying MEMORY.md changes.

Returns a graph view (nodes/edges) over the same locally harvested metadata-only index of public scientific assets as the metadata-search listing, linking assets to their sources. Metadata pointers only -- no underlying datasets, papers, or model weights are downloaded or resold.

x402 market intelligence with current catalog-attributed USDC flow, address-level demand signals and separately labeled value-matched history. The headline covers Base only (market.universeChains); the multi-chain picture ships alongside it as ecosystem, split into an RPC-proven floor and an indexed upper bound that are not additive (notASum). Attribution is not exclusive protocol-intent proof.
