🔬 ChEMBL Assays Scraper

🚀 Export ChEMBL bioactivity assay records in seconds. Description, type, organism, target, document, confidence score, and cell line.

The ChEMBL Assays Scraper turns the public ebi.ac.uk/chembl/api/data/assay endpoint into a structured dataset. It supports list, target-scoped, search, and exact-ID modes, and exposes every assay filter the API accepts.

🎯 Target Audience	💡 Primary Use Cases
💊 Drug discovery teams	Snapshot assays for a target
🧪 Bioinformaticians	Mirror ChEMBL assays into a warehouse
📊 Computational chemists	Filter by confidence score and assay type
🛡️ Pharma BD	Cross-reference assays with documents
👩‍🔬 Academic researchers	Build assay-to-target matrices
👩‍💻 Developers	Drive an assay browser UI

📋 What the ChEMBL Assays Scraper does

• Calls the public /data/assay endpoint with the filters you provide.
• Supports list, target-scoped, free-text, and exact-ID modes.
• Filters by assay type, organism, and minimum confidence score.
• Pushes a clean diagnostic record on upstream errors.
• Exports to every Apify dataset format.

💡 Why it matters: Assays are the bridge between targets and compounds. Mirroring them lets you build the full target-assay-activity graph in your own warehouse.

📊 Data fields

Each record includes: assayChemblId, assayType, cellChemblId, confidenceScore, description, documentChemblId, organism, results, scrapedAt, targetChemblId. 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: ChEMBL paginates 200 records per page. The actor walks pagination until maxItems is hit.

🚀 How to use

1. Click Try for free.
2. Provide a target id, assay id, or other filters.
3. Click Start and download the dataset.
