Compute a molecular formula's weight and composition

Parses a molecular formula (with nested parentheses/brackets and multipliers, e.g. 'C9H8O4', 'Ca(OH)2', 'Fe2(SO4)3') and returns its molecular weight, monoisotopic weight, per-element counts, and mass composition. Fully local — bundled IUPAC/CODATA atomic weights, no upstream. Unparseable formula or unknown element -> confidence 0.0. Charges 1 cost_unit.

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.
