⚗️ ChEMBL Compounds Scraper

🚀 Export ChEMBL chemical compounds in seconds. ChEMBL IDs, names, molecular formulas, weights, SMILES, InChI, and clinical phases — direct from the public ChEMBL REST API.

The ChEMBL Compounds Scraper turns the ChEMBL REST API public endpoint into a clean, structured dataset. It queries the source live, normalizes the response into one row per record, and pushes the result into an Apify dataset you can download or pipe to your warehouse.

More than two million bioactive molecules curated by ChEMBL at EBI are covered in a single run, with stable field names and null-safe parsing.

🎯 Target Audience	💡 Primary Use Cases
💊 Medicinal chemists	Inventory bioactive compound space
🧪 Drug discovery	Filter by clinical phase for repurposing
🎓 Educators	Build cheminformatics teaching sets
🤖 ML teams	Train molecular property predictors

📋 What the ChEMBL Compounds Scraper does

• Calls the public ChEMBL REST API endpoint with the parameters you supply.
• Parses the response and flattens each record into a single dataset row.
• Casts numeric fields to numbers where applicable for clean spreadsheet imports.
• Surfaces rate-limit or upstream errors as a single-row error record instead of crashing.
• Exports to every Apify dataset format supported in the UI.

💡 Why it matters. The raw ChEMBL REST API response is great for API consumers but awkward for spreadsheets and BI tools. This actor normalizes the shape so the data drops straight into pandas, BigQuery, or a Google Sheet.

📊 Data fields

Each record includes: atc_classifications, canonical_smiles, chembl_id, inchi, indication_class, max_phase, molecular_formula, mw, pref_name, results, scrapedAt, structure_type. These field names come straight from the actor's dataset schema, so what you see here is what lands in your dataset.

⚠️ Good to Know. This actor calls the public ChEMBL REST API endpoint with no authentication required. Upstream rate limits apply; if the source returns a limit notice, you will see it as a single error record in your dataset.
