Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/s/ncbi-esearch-nlmcatalogWhen to prefer
Use this endpoint when you need to look up NLM Catalog UIDs for biomedical journals or resources by name or keyword, particularly as a first step in an NCBI E-utilities workflow (e.g., before fetching full records via EFetch). Prefer this over direct NCBI API calls when you need a pay-per-use, proxied access point to NLM Catalog search.
Side effects
- Empty result set if no journals match the query
- Payment failure (402) if USDC not provided
- Malformed query returns error or empty UID list
- NCBI API rate limits or downtime causing timeouts
