Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
get_data_freshnessReturns when the data was last activated, how many segments are live, and the state of the last run. Call this first when you need to know whether the data is fresh.
list_drug_shortagesCurrent and resolved US drug shortages as reported by the FDA. Each row carries the generic name, the reporting company and its company_id. Filters: status, generic_name, company_id, limit.
statusstringgeneric_namestringcompany_idstringlimitinteger
list_drug_recallsFDA drug recalls and enforcement reports. Filters: classification (Class I, II, III), company_id, limit.
classificationstringcompany_idstringlimitinteger
list_federal_drug_contractsUS federal contracts for drugs, product service code 6505, from USAspending. Filters: agency, company_id, limit.
agencystringcompany_idstringlimitinteger
get_supplier_exposureThe join: a federal contract whose supplier has an FDA shortage or recall. Every row carries company_name, confidence (exact, probable or weak) and match_method. A cross source join is NEVER exact, because FDA and USAspending share no identifier. The claim is: this government supplier has an active FDA shortage or recall. It does NOT claim that this contract delivers that drug. Without a key you get exact and probable matches only, at most 20 rows, without the evidence field.

Availability history
Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Era history
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
Response time history
The two probe legs separately: modern server/discover and legacy initialize.
Event log
Derived by comparing consecutive probes — changes in era, protocol version, build and reachability.
