Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/s/ncbi-esearch-booksWhen to prefer
Use this endpoint when you need to discover NCBI Bookshelf UIDs for biomedical or medical textbooks matching a topic or keyword — especially as a first step before fetching full book details via other NCBI E-utilities. Prefer this over general web search when you need structured NCBI identifiers for downstream processing, citation, or programmatic retrieval of book content.
Side effects
- Empty result set if the query matches no books in the Bookshelf database
- Malformed or missing query parameter returns an error or empty response
- NCBI E-utilities rate limiting or downtime causes failures
- Overly broad queries return an unmanageably large list of UIDs
- Spelling errors in the query yield zero or irrelevant results
