Current and resolved US drug shortages from openFDA, newest update first. Optional `?company=Pfizer` narrows to one manufacturer (omit for market-wide); `?limit=` (max 100). Each carries the generic name, company, status, therapeutic category, dosage form, presentation, posting/update dates, and reason. A supply-side catalyst for generic makers. From x402stock

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.

Availability: 100
Latency: 61
Security: 100
Transparency: 61
Activity: not yet measured

Confidence 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.

See the scoring methodology for exactly how each number is computed.
