Chemical spaces and capabilities
Discover releases, supported operations, limits, registries, and sampling semantics.
Call GET /api/v2/catalog at runtime. Each library reports its immutable release, product/synthon/
reaction counts, search scorers, substructure coverage, sampling method, property/preset/pattern
registries, predicted-property endpoints and acquisition operations, price availability, exact or
approximate fidelity, synchronous limits, and durable-run budgets.

--header "x-api-key: $DMC_API_KEY"Capabilities are release-specific and are derived from the signed assets loaded by the worker.
Never assume every database supports substructure, constrained sampling, a predictive model, or the
same distribution. An unsupported combination fails validation instead of being ignored. Store
database_id plus returned release_id for reproducibility. Predicted-property entries include
their model version, units, and experimental-acquisition-only qualification; currently advertised
operations support only ranked similarity shortlist acquisition.
Prices
When available, every result includes price as a positive whole number of US dollars. The default
context is delivery to the United States. A missing or
unsupported price is null, never zero. The catalog advertises support through
pricing.available.
