How this service works
Compare supplied molecules using a declared fingerprint and similarity metric. For dataset analysis; chemical similarity does not establish equivalent function or safety.
Output
Returns a structured receipt containing a similarity result object, a version identifier (maha-microproducts/0.1), an offer ID (chemistry-fingerprint-similarity), the amount charged in base units (28001), an input digest, a receipt digest, and a boundaries array — the core similarity score is inside the result object.
Example use cases
Drug candidate structural comparison
“I have two candidate drug molecules — 'CC(=O)Oc1ccccc1C(=O)O' and 'CC(=O)Nc1ccc(O)cc1' — can you compute their chemical fingerprint similarity using the public data class to see how structurally close they are?”
Synthetic compound similarity screening
“Compare these two synthetic molecules for me: 'C1CCCCC1' and 'C1CCNCC1' — use the synthetic data class and tell me their fingerprint similarity score.”
Lead optimization structural check
“During lead optimization, I want to check how similar my modified compound 'CCc1ccc(NC(=O)c2ccc(Cl)cc2)cc1' is to the original scaffold 'CCc1ccc(NC(=O)c2ccccc2)cc1' — can you run a public-class fingerprint similarity comparison?”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/micro/chemistry-fingerprint-similarity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, auditable, per-call paid computation of molecular fingerprint similarity between exactly two molecules, particularly when working with public or synthetic chemical datasets. Prefer it over full cheminformatics suites when you want a lightweight, reproducible, receipt-backed pairwise comparison without standing up local tooling. It is not a substitute for pharmacological equivalence or safety assessment.
Side effects
- Invalid or unparseable molecule string — returns an error if left or right strings cannot be interpreted as valid molecular representations
- Missing required fields (left, right, dataClass) — returns a validation error
- dataClass enum mismatch — only 'public' or 'synthetic' are accepted
- Molecule string exceeds 512 character limit — rejected with a length error
- Payment failure — x402 payment not accepted or insufficient funds
