## 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 patentpulse-prior-art-search-f5838a04
```

Example prompt: Can you run a prior art search for my invention — a self-heating coffee mug that uses a thermoelectric module powered by wireless charging to maintain beverage temperature — and tell me whether it's likely patentable and what existing patents might block it?

## When to prefer this

Use this endpoint when an inventor, patent agent, or IP professional needs to quickly assess whether an invention is novel before filing a patent application, or when an AI agent needs to surface prior art references as part of a patent prosecution or IP due diligence workflow. Prefer this over generic web search when structured USPTO and global patent database coverage with a patentability opinion is required.

## Known failure modes

- Vague or overly broad invention description may return low-quality or irrelevant prior art
- No prior art found may indicate either a truly novel invention or insufficient search terms
- API may return timeout for extremely broad technology domains
- Payment failure at $0.12 USDC per call if x402 payment is not properly configured
- Rate limiting if too many calls are made in quick succession

## How this service works

Prior art search / novelty search / patentability check for an invention or claim. Searches USPTO patents (abstract + title), EPO/WIPO/JPO global filings, and 200M+ academic papers (OpenAlex) to surface prior art and assess patentability and novelty before filing. For inventor and patent agents. Worldwide.

## Output

Returns a structured patentability and novelty analysis including relevant prior art references found in USPTO and global patent databases, an assessment of the invention's novelty, and a patentability opinion indicating whether the invention is likely novel and non-obvious over the prior art.
