Designing a Drug Interaction API

Make pair identity, missing records, errors, and metering explicit in the contract.

Canonicalize pairs

Canonicalize pairs is the first design decision for drug interaction API design. Make pair identity, missing records, errors, and metering explicit in the contract. Write the boundary down before choosing endpoints or drawing clinical-looking UI so reviewers can test the actual promise.

Separate resolution from lookup

For drug interaction API design, separate resolution from lookup should remain observable rather than becoming hidden adapter behavior. Give resolution, lookup, and interpretation separate states, then decide which failures a user may retry.

Represent missing records honestly

Represent missing records honestly needs an operational test, not only a happy-path example. Add a bounded timeout, stable error handling, request IDs, privacy-safe logging, and a fixture that proves the drug interaction API design workflow fails closed.
