# Monitor FDA Drug Supplier Registration Changes

**Use case:** 

Monitor supplier registrations in FDA DECRS. Replace the sample FEI and 9-digit DUNS, choose a monitorId and reuse it without overlapping runs. The first run saves a baseline; later runs identify status, expiration, operation and address changes. The changes view is empty until a verified change occurs; the overview retains every input.

## Input

```json
{
  "establishments": [
    {
      "fei": "0000000360",
      "duns": "271408412",
      "reference": "replace-with-your-supplier"
    }
  ],
  "mode": "monitor",
  "monitorId": "my-fda-drug-supplier-watchlist",
  "onlyChanges": true,
  "dueSoonDays": 90,
  "includeAddress": true
}
```

## Output

```json
{
  "reference": {
    "label": "Your reference",
    "format": "string"
  },
  "source_id": {
    "label": "Stable observation ID",
    "format": "string"
  },
  "firm_name": {
    "label": "Published firm name",
    "format": "string"
  },
  "registration_status": {
    "label": "FDA publication state",

  },
  "changes": {

  },
  "scraped_at": {

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
