## Known failure modes

- Empty result set if query matches no indexed papers
- Rate limit or payment error if x402 payment fails or is insufficient
- Malformed or missing ?q= parameter returns error or empty results
- PubMed API downtime causes upstream failure
- Very broad queries may return irrelevant or overwhelming results
