## 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 gateway-sanfoundation-com-ab67471c
```

Example prompt: Can you pull up the full details for SAN event evt_552c9dded5b98f799ab42cb9 — I need the title, summary, tags, and source articles it links to.

## When to prefer this

Use this endpoint when you have a specific evt_… identifier cited in a SAN report or returned by a SAN agent's event list, and need to retrieve the full canonical event envelope — including its summary, tags, status, and all underlying source articles. Prefer this over listing or searching endpoints when you already know the exact event ID and want authoritative detail on a single event.

## Known failure modes

- Unknown or malformed evt_ ID returns 404 or empty event object
- Transient gateway error returns 5xx with no event data
- Payment not processed leads to 402 Payment Required before response is delivered
- Event ID exists but has been deprecated or merged, returning partial data

## How this service works

Retrieves a specific x402 event record behind a paid access gate.

## Output

Returns a JSON object with the full event envelope: eventId, title, summary, status (e.g. 'developing'), tags array, and a sources array containing URLs, publication names, and publish timestamps for each underlying article that was collapsed into the canonical event.
