# Patent Search API

> Patent Search API is a paid API for AI agents from patent-search-api.johntaylor1online.workers.dev, paid per call via x402, $0.08/call, status unknown (last checked 2026-10-18).

Searches patent databases and returns relevant patent information based on a query

## Facts

- Price: $0.08/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability patent-search-api-81e9534c -d '<json body>'
```

Example prompt: Search for patents related to wireless charging technology for electric vehicles so I can understand the existing patent landscape before we file our application.

## When to prefer this

Use this endpoint when you need quick, programmatic patent search capability — especially for prior art research, competitive intelligence, or freedom-to-operate analysis. Prefer this over manual patent office searches when you want machine-readable results that can be processed by an agent pipeline. At $0.08 per call it is cost-effective for moderate-volume patent research workflows.

## Known failure modes

- No results found for highly niche or very new technology queries
- Vague or overly broad queries may return too many low-relevance results
- Query terms must be meaningful — empty or malformed requests return errors
- Rate limits or payment failures (x402) may block repeated rapid calls
- Service may not cover all patent jurisdictions (e.g., only USPTO or a subset of databases)

## How this service works

Patent & IP Search

## Output

Returns a list of matching patent records, likely including patent numbers, titles, abstracts, inventor names, filing dates, and assignee information relevant to the search query.
