Endpoint
POSThttps://x402-v2-mint-pubmed-search.vercel.app/v1/pubmed-search/fmt/json-pick?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, keyless PubMed search returning structured JSON with optional article metadata (title, journal, pubdate) for up to 10 results. Prefer it over raw NCBI E-utilities calls when you want a simple pay-per-call API without managing an NCBI API key, and when you need the JSON-pick format specifically (structured field selection rather than raw XML or full records).
Side effects
- Query string missing or malformed — returns error with no results
- retmax exceeds limit of 10 — capped or returns error
- NCBI E-utilities temporarily unavailable — upstream timeout or 5xx error
- No results found for query — returns count 0 and empty ID list
- Malformed JSON response if upstream NCBI API changes format
