Validated Scientific Solver Index
Ranked lookup over a registry of validated numerical PDE solvers. POST /execute/polymathica-validated-solver-index-v1 takes a query and returns records carrying solver family, the PDE families covered, validation state and version, module and evidence paths, a summary and a relevance score. $0.005 USDC per call on Base, no API key. Scope, established by a paid call: this is the provider's own internal validated index, snapshotted 2026-08-13, and it is not a public literature search, package registry or citation index. Admission is limited to entries that are implemented and marked validated. The module and evidence paths refer to the provider's own repository, so a buyer cannot independently resolve or execute the listed solvers from the response alone. Registry evidence summary only: not a new solver execution and not an engineering certification.
