## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **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`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## OpenFDA Recall Delta Feed

Materialized change feed for FDA drug recalls (openFDA `drug/enforcement`).

### Input

- `source`: `openfda_drug_enforcement` (única implementada).
- `changeType`: `new`, `updated`, `any` (default `any`).
- `limit`: 1–200 (default 50).
- `maxTotalChargeUsd`: opcional; debe ser >= $0.01 (start fee).

### Output

Un dataset item por delta válido materializado:

```json
{
  "source": "openfda_drug_enforcement",
  "external_id": "D-1074-2017",
  "observed_at": "2026-08-15T00:00:00",
  "change_type": "new",
  "changed_fields": ["recalling_firm", "reason_for_recall"],
  "old_hash": "",
  "new_hash": "sha256...",
  "payload": { "recall_number": "D-1074-2017", ... }
}
```

### Semántica

- Primera corrida: baseline (todos `new`).
- Corridas siguientes: `new` si el `external_id` no existía en el estado previo;
  `updated` si el hash del payload cambió.
- Estado previo en el Key-Value store del actor (`seen` map `external_id -> content_hash`).
- `unchanged` no se emite.

### Pricing / cobro

- Evento PPE: `delta` (por item materializado). Se cobra SOLO después de `push_data` exitoso.
- Fail-loud: si el pricing configurado no incluye el evento `delta`, el run FALLA visiblemente
  (sin sustitución silenciosa del modelo de cobro).
- Sin pricing configurado (draft/owner): no se cobra, run normal.

### Limitaciones

- `changed_fields` para `updated` usa `["$root"]` (el KV store no persiste payloads completos);
  los campos exactos requieren el snapshot local (motor Boring Data Engine).
- openFDA no debe usarse para decisiones clínicas; feed informativo con provenance.

# Actor input Schema

## `source` (type: `string`):

## `changeType` (type: `string`):

Filter deltas: new, updated, or any.

## `limit` (type: `integer`):

Maximum number of delta items to return (1-200).

## Actor input object example

```json
{
  "source": "openfda_drug_enforcement",
  "changeType": "any",
  "limit": 50
}
```

# Actor output Schema

## `source` (type: `string`):

Source identifier.

## `external_id` (type: `string`):

Stable record identifier (recall\_number or event\_id).

## `change_type` (type: `string`):

new or updated.

## `observed_at` (type: `string`):

Source report date of the record.

## `new_hash` (type: `string`):

## `phase` (type: `string`):

Meta marker: fetch or done.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("bahc19/openfda-recall-delta").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("bahc19/openfda-recall-delta").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{}' |
apify call bahc19/openfda-recall-delta --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,bahc19/openfda-recall-delta"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
