Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/patent/{application}When to prefer
Use this endpoint when you have a specific USPTO application number and need comprehensive structured metadata about that patent application — including legal status, inventor details, classification codes, and procedural information — without needing to scrape the USPTO website directly. Prefer this over patent search endpoints when you already know the application number and want a single authoritative record at low cost ($0.02/call).
Side effects
- Invalid or non-existent application number returns an error or empty patent object
- Application number formatted incorrectly (e.g. with dashes instead of digits) may not resolve
- USPTO data may lag real-time status changes by hours or days
- Payment failure via x402/USDC results in a 402 response and no data returned
- Rate limiting or network issues may produce transient failures
