## 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 skim-x402-ecosystem-feed-eb91cd61
```

Example prompt: Pull the latest 50 entries from the x402 ecosystem feed so I can see which new services and price changes have been registered across the public x402 registries in the last refresh cycle.

## When to prefer this

Use this endpoint when you need a structured, aggregated, real-time-ish view of the entire x402 ecosystem — new service listings and price changes — without scraping individual registries. It is purpose-built for agents that need to monitor or discover x402-compatible APIs programmatically. Prefer it over manual registry browsing or one-off lookups when you want a polling-friendly feed with a 15-minute freshness guarantee.

## Known failure modes

- Registry downtime causes stale (up to 15-minute-old) data to be served rather than an error
- Limit parameter out of range (must be 1–100) returns a validation error
- Payment failure or insufficient USDC balance results in a 402 response blocking the call
- Network timeout if the aggregation layer is slow during a refresh cycle

## How this service works

Skim: x402 ecosystem feed — new services and price changes across the public x402 registries, as structured items. Refreshed on a 15-minute cycle (stale served if a registry is down); poll as often as you like.

## Output

A structured, newest-first list of feed items (up to the requested limit, default 50) describing new service registrations and price changes across public x402 registries. Each item includes metadata about the service or price event. Stale cached data is served if a registry is temporarily unavailable.
