How this service works
Search NCBI Nucleotide (GenBank) and return matching UIDs for query {q} via E-utilities. Query: ?q= Returns JSON.
Output
A JSON object containing a list of NCBI Nucleotide UIDs (numeric identifiers) matching the search query, which can then be used to fetch full sequence records from GenBank via other E-utility endpoints.
Example use cases
Example prompt
“Search GenBank's nucleotide database for sequences matching 'BRCA1 homo sapiens' and give me the matching UIDs I can use to fetch the actual records.”
Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/s/ncbi-esearch-nuccoreWhen to prefer
Use this endpoint when you need to discover NCBI Nucleotide / GenBank record UIDs for a biological query (gene, organism, accession, keyword) as a first step before fetching full sequence records. Prefer this over direct NCBI API calls when you need a simple, paid-per-call REST interface without managing NCBI API keys or rate limits.
Side effects
- Empty result set if no nucleotide records match the query
- Malformed or overly broad query returning too many UIDs
- NCBI E-utilities rate limiting or downtime causing failure
- Invalid query syntax returning an error response
- Network timeout if NCBI backend is slow to respond
