## 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 x402-data-api-new-listings-feed-9459af71
```

Example prompt: Show me x402 APIs that appeared in the CDP Bazaar in the last 3 days, up to 20 results, and only include ones that already have at least 2 payers.

## When to prefer this

Use this endpoint when you need a recency-sorted feed of newly discovered x402 APIs from the CDP Bazaar — particularly useful for monitoring market growth, finding fresh listings, or filtering for new APIs that already have paying users. Prefer this over the trending/top-payers endpoint when novelty matters more than popularity.

## Known failure modes

- days parameter out of range (must be 1-30) returns validation error
- limit parameter out of range (must be 1-50) returns validation error
- no new listings in the requested window returns empty results array with total 0
- upstream Bazaar data unavailable causes service error
- payment not included or insufficient USDC results in 402 response

## How this service works

x402 APIs that appeared in the CDP Bazaar in the last days, newest first, optionally only those already paid by some buyers.

## Output

A JSON object containing the total count of matching listings, a tracking_since timestamp indicating when monitoring began, and an array of results each with the resource URL, first_seen ISO timestamp, and payers_30d count for each newly discovered x402 API.
