Endpoint
POSThttps://x402-v2-mint-pubmed-search.vercel.app/v1/pubmed-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need keyless, pay-per-call access to PubMed literature search without managing an NCBI API key. It is ideal for AI agents that need to search biomedical and clinical literature on demand, retrieve article metadata alongside PubMed IDs, and integrate easily into automated research workflows via the x402 micropayment protocol.
Side effects
- Empty or malformed query string returns no results or an error
- retmax exceeding 10 is rejected by schema validation
- NCBI E-utilities rate limiting or downtime causes upstream failure
- Very broad queries may return high counts but only up to 10 IDs
- Payment failure via x402 protocol blocks the request
