TruthBear Drug Shortage Detail – 3-Leg Chain
x402
TruthBear Drug Shortage Detail – 3-Leg Chain is a paid API for AI agents from api.truthbear.co, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).
Runs a sequential three-leg supply-chain analysis for a single drug, connecting labeler availability narrowing to FDA shortage status per NDC to confirmed affected presentations.

How this service works
[3-LEG] Per-drug shortage chain, one drug (?entity=carboplatin): leading supply narrowing - available labelers against total listed -> current current FDA shortage status per NDC -> realized affected presentations (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: openFDA. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.
Output
A JSON object with up to three sequentially gated legs: (1) active labelers vs. total listed labelers indicating supply narrowing; (2) current FDA shortage status per NDC; (3) confirmed affected drug presentations. The confidence field indicates how many legs returned data (0–3). Returns HTTP 422 with no charge if no data is available.
Example use cases
Oncology pharmacist shortage check
“Pull the shortage chain analysis for methotrexate — I need to know if labeler supply is narrowing, which NDCs are on the FDA shortage list, and which presentations are actually confirmed as affected.”
Hospital formulary risk assessment
“Run the 3-leg supply chain check for epinephrine — I want to see the labeler count versus total listed, any active FDA shortage statuses by NDC, and which presentations have been confirmed shortage-impacted.”
Drug supply monitoring alert
“Check the drug shortage chain for oxaliplatin right now — how confident is the signal, are there fewer active labelers than listed, and has the FDA officially flagged any NDCs or presentations?”
Technical details
Endpoint
GEThttps://api.truthbear.co/gauge/drug-detail-regionWhen to prefer
Use this endpoint when you need a structured, multi-signal confirmation of drug shortage status that goes beyond a simple FDA lookup — specifically when you want to correlate labeler supply narrowing with official NDC shortage listings and presentation-level confirmation in a single chained call. Prefer it over raw openFDA queries when you need a confidence-gated, sequential analysis rather than a single data point.
Side effects
- 422 no_charge returned when no data exists for the given entity — not billed
- Invalid or unrecognized entity name returns an error or empty result
- openFDA upstream outage may reduce the number of legs that can be populated, lowering confidence score
- Querying a drug not in the monitored catalog returns no meaningful chain data
