# OneShot Agent API – Drug Shortage Lookup

> OneShot Agent API – Drug Shortage Lookup is a paid API for AI agents from win.oneshotagent.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-23).

Looks up current FDA drug shortage data by drug name and/or status, returning shortage details including reason, availability, company, and NDC.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability oneshot-agent-api-drug-shortage-lookup-2655d092 -d '<json body>'
```

Example prompt: Can you check if quinapril is currently in shortage? Show me up to 5 results with current status only.

## When to prefer this

Use this endpoint when you need structured FDA drug shortage data for a specific drug, including reason, NDC, company, and status. Prefer this over general web search when you need machine-readable shortage records with official FDA sourcing, especially for pharmaceutical agents, healthcare workflows, or supply chain monitoring tasks.

## Known failure modes

- Drug name not found — returns empty shortages array with total 0
- Invalid status enum value — request rejected with validation error
- Limit parameter ignored or causes unexpected truncation if set too high
- Drug name misspelled or brand name not recognized — may return no results
- Payment failure via x402 — 402 response if USDC balance insufficient

## How this service works

Say whether the US Food and Drug Administration lists a drug as in shortage, and for each listed presentation who makes it, whether it is available and why it is short.

## Output

Returns a JSON object with a total count and an array of shortage records, each containing the drug's generic name, brand names, dosage form, NDC, company name, current status (current/to_be_discontinued/resolved), reason for shortage, availability description, therapeutic category, and first posted and last updated dates.
