## 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 epo-patent-bibliographic-record-lookup-bb4b3a9d
```

Example prompt: Pull the bibliographic record for patent EP1000000 — I need the title, inventors, applicants, IPC classifications, and abstract.

## When to prefer this

Use this endpoint when you need structured bibliographic metadata (title, inventors, applicants, IPC codes, abstract) for a specific patent by its publication number. Ideal for worldwide patent coverage including both EP and US patents. Prefer over full-text patent retrieval when bibliographic summary is sufficient. Best when you already know the publication number.

## Known failure modes

- Invalid or malformed publication number returns an error
- Unrecognized number format causes lookup failure
- Patent publication not found in EPO OPS database returns empty or 404 response
- Rate limiting or payment failure returns 402 or 429
- Unsupported format enum value causes validation error

## How this service works

Bibliographic record for a patent publication via EPO OPS: invention titles (multiple languages), applicants, inventors, IPC classifications, application number, and the abstract. Worldwide coverage by publication number (e.g. EP1000000, US6093011). Net-new vs US-only patents.detail.

## Output

Returns structured bibliographic data for the requested patent publication: invention title in one or more languages, applicant and inventor names, IPC classification codes, application number, and the patent abstract. Covers patents worldwide by publication number (e.g. EP or US format).
