Validate a SMILES string and return its canonical form

Validates a SMILES string against PubChem's structure registry and returns the canonical/isomeric SMILES, formula, molecular weight, and CID. is_valid=True means PubChem recognized and standardized the structure; a malformed or novel-not-in-PubChem structure is is_valid=False (this checks against PubChem, not pure SMILES grammar; a malformed SMILES is a PubChem verdict and bills the full rate). Redis-cached 30 days. Charges 2 cost_units; 1 when the input is empty (PubChem never called).

Query parameters

include_receiptboolean

Set true to attach an execution receipt at meta.receipt — caller-verifiable sha256 hashes over the RFC 8785 (JCS) canonicalization of this call's as-received JSON body and its result (free, like include_trace). Reproduce with any JCS library: input_hash = sha256(jcs({"tool": <request path>, "args": <your body minus include_trace/include_receipt>})); result_hash = sha256(jcs(result)). For deterministic tools, same input on the same build reproduces result_hash.
