🧬 NCBI dbSNP Variants Scraper

🚀 Pull human SNP variants from NCBI dbSNP in seconds. rsIDs, chromosome and position, alleles, functional class, gene context, clinical significance and global minor allele frequencies from the official NIH database.

🕒 Last updated: 2026-05-27 · 📊 22 fields per record · 1B+ rsIDs · Global population frequencies

NCBI dbSNP is the world's authoritative public catalogue of single-nucleotide variants. This scraper wraps the official E-utilities esearch + esummary flow and returns a clean, structured table for any gene, condition or rsID query.

Every record carries the rsID, SPDI string, chromosome position, allele, functional class (intron/upstream/exon), gene symbols and Entrez IDs, validation status, clinical significance and global MAFs from 1000Genomes, gnomAD, TOPMED, TOMMO, ALFA and more.

📋 What the NCBI dbSNP Variants Scraper does

• Calls the official E-utilities esearch to resolve a gene/condition/rsID query
• Calls esummary to fetch full variant metadata
• Returns rsID, SPDI, chromosome, position, alleles, gene context, clinical significance, global MAFs
• Stream-delivers to multiple table outputs

💡 Why it matters: every clinical and pharmacogenomic analysis starts with annotating variants. dbSNP is the canonical source - and this actor makes it queryable from a spreadsheet workflow.

⚙️ Input

{"query":"BRCA1","maxItems":25}

{"query":"rs328","maxItems":1}

⚠️ Good to Know: NCBI E-utilities is rate-limited to 3 requests/sec without an API key. The actor batches IDs into a single esummary call to stay well under the limit.

❓ Frequently Asked Questions

Do I need an NCBI API key? No, but providing one increases your rate limit to 10 req/sec. The actor uses unauthenticated mode by default.

Is dbSNP human only? Currently human-focused. Other species are available via the same E-utilities pattern but with different taxonomyId.

Can I query by rsID directly? Yes - set query to rs328 or 328.

Are clinical-significance annotations from ClinVar? dbSNP propagates ClinVar annotations into the summary. Always verify in ClinVar for clinical use.

What's SPDI? The Sequence-Position-Deletion-Insertion notation: NCBI's modern standard for variant representation.

How fresh is dbSNP? dbSNP releases new builds periodically. The actor returns whatever the live API serves.

Can I get VCF output? This actor produces a tabular summary. Combine with NCBI's VCF use for raw genotyping.

Is the actor rate-limited? The actor stays under 3 req/sec to comply with E-utilities limits.

Are alternate assemblies supported? The actor returns the canonical GRCh38 position. Other assemblies require manual liftover.

Can I batch thousands of rsIDs? Yes - set maxItems accordingly. The actor batches into a single esummary call.

🔌 Integrate with any app
