## How to call it through Zero

```sh
zero fetch --capability x402-listing-watch-c2eb8223
```

Example prompt: Can you check if my x402 service at myapi.xyz is still listed in the Bazaar — and show me how its resource count has changed over the past few days and when it was last paid?

## When to prefer this

Use this endpoint when you need to verify whether a specific x402 service domain is still actively listed in the Bazaar and want historical trend data on its resource count and payment recency. It is the only known service tracking daily Bazaar catalog snapshots since June and can surface silent delistings that the Bazaar itself does not notify operators about.

## Known failure modes

- Domain not found in historical snapshots — returns no data or empty history if domain was never tracked
- Invalid domain format — may return a validation error
- Omitting the domain parameter returns market-wide stats instead of per-domain info, which may confuse callers expecting domain-specific results
- Stale snapshot — data reflects daily cadence so intraday changes won't appear immediately

## How this service works

Is your x402 service still listed? The Bazaar removes resources that go without settlement, and no one tells you. We keep a daily snapshot of the whole catalog since June, so we can show whether your domain is present today, how its resource count moved day by day, and how long since each resource was last paid for. In our latest scan 620 of 2,147 domains are no longer present. Measured from our own snapshots.

## Output

Returns whether the queried domain is currently present in the Bazaar catalog, a day-by-day history of its resource count since June, time elapsed since each resource was last settled, and optionally market-wide statistics on how many of the ~2,147 tracked domains are no longer listed.
