Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-6bea87f6
```

Example prompt: Show me the x402 APIs that were newly listed in the CDP Bazaar over the last 5 days, and only include ones that already have at least 2 buyers — give me up to 30 results.

## When to prefer this

Use this endpoint when you need to discover the most recently added x402 APIs in the CDP Bazaar, especially when you want to monitor new market entrants or find new APIs that have already attracted paying users. Prefer it over the ranked or category endpoints when recency is the primary sorting criterion rather than popularity or uptime.

## Known failure modes

- days parameter out of range (1-30) returns validation error
- limit parameter out of range (1-50) returns validation error
- min_payers set too high yields empty results array with total=0
- Payment not attached or insufficient USDC returns 402 Payment Required
- Service temporarily unavailable returns 5xx error

## How this service works

Data about the x402 market: the CDP Bazaar's listings, sellers, prices and categories, new listings and price changes from snapshots every 6 hours, uptime we measure for every paid listing, and x402 spending of any wallet and revenue of any seller on Base.

## Output

A JSON object containing: total count of matching listings, an array of result objects each with the API's resource URL, first_seen ISO timestamp, and payers_30d count, plus a tracking_since timestamp indicating when monitoring began.
