ANVISA Medicine Scraper 💊

Extracts complete data on registered medicines from ANVISA (Brazil's National Health Surveillance Agency), including commercial presentations, domestic and international manufacturers, ATC classification, therapeutic class, and registration holder details.

Why this Actor?

ANVISA's consultation portal is protected by a WAF (Cloudflare + Dynatrace), which blocks direct HTTP calls to the API — any request without valid session cookies gets a 403 Forbidden.

This Actor solves the problem using Playwright (a real headless browser) that:

1. Resolves WAF challenges automatically — Cloudflare and Dynatrace are handled as part of normal browser navigation
2. Intercepts JSON responses from the internal API — more robust than CSS selector scraping, won't break if the UI changes
3. Returns complete, structured data — same depth of data available in each medicine's detail panel

Input

Input examples

How it works

┌─────────────────────────────────────────────────────────┐
│ 1. Playwright navigates to the ANVISASPA │

├─────────────────────────────────────────────────────────┤
│ 2.DEFAULTroute: Paginated listing API │
│ → fetch() via browser context(withWAF cookies) │
│ → Filters out NOTIFICADO(notified-only) products │
│ → Enqueues DETAILfor each REGISTERED product │
│ → Next page if available │
├─────────────────────────────────────────────────────────┤
│ 3.DETAILroute: Per-product detail API │

│ → Maps JSON to Medicine structure │
│ → Saves to Dataset via pushData() │
└─────────────────────────────────────────────────────────┘

The scraper does not rely on CSS selectors — it intercepts JSON responses from the internal API that ANVISA's own Angular SPA consumes. This makes extraction resilient to visual changes in the portal.

🔌 Integration & API

You can easily integrate this Actor into your own data pipelines, backend applications, or BI tools using the Apify API.

Starting the Actor via REST API

Trigger a run by sending a POST request to the Apify API, passing your parameters in the JSON body:

curl"https://api.apify.com/v2/acts/YOUR_USERNAME~anvisa-raw-material-scraper/runs?token=YOUR_API_TOKEN"\
-H"Content-Type: application/json"\
-d'{
 "startDate": "01/04/2025",
 "endDate": "30/04/2025",
 "maxPages": 1
 }'

Note: Replace YOUR_USERNAME~anvisa-raw-material-scraper with your actual Actor ID and provide your Apify API Token.

Fetching the Results

Once the run finishes, download the extracted data (in JSON, CSV, or Excel format) directly from the run's dataset:

$curl"https://api.apify.com/v2/datasets/DATASET_ID/items?format=json"

For more details on integrating Apify Actors via Node.js, Python, or REST, refer to the official Apify API documentation.

Tech stack

• Crawlee — Web scraping framework
• Playwright — Browser automation
• Apify SDK — Actor platform
• TypeScript — Strict typing

Limitations and considerations

• Rate limiting: The crawler runs with a max concurrency of 3 to be respectful to ANVISA's servers
• WAF: In rare cases, the WAF may require manual CAPTCHA solving. The automatic retry (3 attempts) usually handles it
• Proxy: In production on Apify, using a proxy is recommended to avoid IP-based blocks. The Actor attempts to configure a proxy automatically and works without one if no credits are available
• Data volume: Each listing page contains 10 products. For long date ranges, the volume can be large — use maxPages to limit during testing.
