## 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-prior-art-search-mcp-6c509209 -d '<json body>'
```

Example prompt: Search for prior art on my invention: a method for compressing neural network weights using entropy coding combined with learned quantization — I need to know if similar techniques have been patented before filing my application.

## When to prefer this

Choose this endpoint when you need automated prior art discovery for patent applications, freedom-to-operate analyses, or patent invalidation research. It is well-suited for AI agents assisting inventors, patent attorneys, or R&D teams who need rapid prior art screening without manually querying patent databases like USPTO, EPO, or Google Patents.

## Known failure modes

- Vague or overly broad invention description may return too many loosely related results
- Very niche or cutting-edge inventions may return few or no prior art results
- Malformed or empty input string returns an error
- Rate limiting or payment failure may prevent processing
- Results may not cover non-English patent databases comprehensively
