authentic

Query the NCBI Gene database via E-utilities and the NCBI Datasets API; use it when you need to search genes by symbol/ID and retrieve annotations (RefSeq, GO, location, phenotype) for single or batch gene lists.

When to use

• You have a gene symbol (e.g., **BRCA1**) and need the correct **NCBI Gene ID** for a specific organism.
• You have an NCBI **Gene ID** and need consolidated metadata (aliases, RefSeq accessions, genomic location, GO, literature links).
• You need to **annotate a gene panel** (dozens to thousands of genes) with consistent identifiers and core annotations.
• You want to search genes by **biological context** (GO terms, phenotype/disease keywords, pathway terms) and then retrieve details for the hits.
• You are building a pipeline that must respect **NCBI rate limits** and handle retries for transient API failures.
