About this data
Search official US patent grants and published applications, enriched with abstracts, inventor names, classifications and optional claims.
From the actor’s Apify Store listing. The per-call endpoint may return a bounded subset; its own description is below.
Buy per call over x402
One endpoint at api.ssh.autos. Each call is one JSON POST, paid in USDC with no account or API key, and answered in the same HTTP response.
POST /v1/us/uspto/patent
Look up one US patent or published application by document number through an anonymous Patent Public Search guest session.
The bibliographic result is joined to public document metadata: title, abstract, publication/grant dates, inventors, applicants/assignees and classification codes where published.
Claims text, broad search, alerts and stored state are excluded.
No private API key or signup is needed for this public route.
Input
Send a JSON body to POST https://api.ssh.autos/v1/us/uspto/patent.

The answer is JSON: records, a list, and summary, the run status and counts. Each record has these 20 fields; a field the source does not publish comes back null.

This data source is a public actor on the Apify Store: USPTO Patents Scraper. Run it with your Apify account and plan for larger, scheduled or exported runs; it may offer more input options than the per-call endpoint.
How x402 payment works
- Your client sends the request. The API answers
402 Payment Requiredwith the price and where to pay. - The client pays from its own wallet: USDC on Base or Solana over x402, or over MPP on Tempo. No account, sign-up or API key.
- The client retries with the payment attached and gets the JSON answer in the same call. You are only charged for answers.
The AgentCash CLI in the example does all three steps for you and pays from your AgentCash wallet. Any x402 or MPP client works the same way.
