## 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`):

```

## When to prefer this

Use this endpoint when you need current FDA drug shortage data — especially when filtering by a specific pharmaceutical company — without needing an API key or subscription. Ideal for AI agents that need pay-per-use access to regulatory drug supply data, pharmaceutical research, or supply chain monitoring. Prefer over scraping the FDA website directly or using general web search when structured, machine-readable shortage data is needed.

## Known failure modes

- No shortages found for the specified company — returns empty shortages array with total_matched of 0
- Invalid limit value (<=0 or >100) — schema validation error
- Company string too short (<2 chars) or too long (>120 chars) — schema validation error
- Payment failure via x402/USDC — 402 Payment Required response
- FDA upstream data unavailable — potential 503 or stale as_of timestamp

## How this service works

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

## Output

A JSON object containing the source ('fda'), an as_of timestamp, the company filter applied (or null), total_matched count, count of returned records, and an array of shortage records each with generic_name, company_name, status, dosage_form, presentation, therapeutic_category, posted_date, updated_date, update_type, reason, and an FDA attribution string.
