How this service works
320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.
Output
An array of interaction objects, each containing the names of the two interacting drugs, a severity rating (e.g. major, moderate, minor), and a plain-language description of the interaction and its clinical significance.
Example use cases
Polypharmacy safety review for elderly patient
“My father is on lisinopril, metoprolol, atorvastatin, and aspirin — can you check all of those for drug interactions and flag anything serious?”
Pre-prescription interaction screening
“Before I take the new prescription for fluoxetine alongside my existing ibuprofen and alprazolam, can you check if there are any interactions I should know about?”
Pharmacist drug combination audit
“Check interactions for this combination: warfarin, clopidogrel, omeprazole, and naproxen — I need the severity and a description for each pair that has a known interaction.”
