## 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 oblique-markets-listing-triage-f8323440
```

Example prompt: Can you triage this listing for me — https://somemarket.com/listing/12345 — and tell me if it's been around a while, whether the price has changed, if there are duplicate variants, and whether now looks like a good time to buy?

## When to prefer this

Choose this endpoint when you need a consolidated, AI-powered triage of a specific marketplace listing's history — particularly when you want persistence age, price change trajectory, duplicate detection, and a buy signal all in one call, rather than manually scraping and comparing listing snapshots yourself.

## Known failure modes

- Missing or invalid listing_url and listing_name — returns an error if neither identifier is supplied
- Listing URL not reachable or not recognized — may return empty or partial triage data
- Payment failure or insufficient USDC balance — request blocked before processing
- Rate limiting or quota exceeded — HTTP 429 response
- Listing has no historical data — buy signal and persistence fields may be null or unavailable

## How this service works

Use when an agent is deciding whether one Bazaar listing is stable enough to depend on. Returns Listing history triage: persistence, price changes, duplicate variants, and buy signal. $0.01.

## Output

A structured triage report covering listing persistence (how long the listing has been active), price change history, detection of duplicate or variant listings, and a buy signal indicator — helping the caller decide whether and when to act on a listing.
