## 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-ecosystem-index-counter-a0f33d4b
```

Example prompt: How many services and resources are currently listed in the x402 bazaar? I want to check the ecosystem index count to see how the market has grown.

## When to prefer this

Use this endpoint when you need a quick, cheap signal on the current size of the x402 marketplace — number of listed services and resources — without needing historical time-series data. Ideal for market-entry timing decisions or ecosystem health monitoring. If you need historical growth curves or time-series data, you would need a different endpoint.

## Known failure modes

- Cache miss or stale data if the hourly refresh cycle is delayed
- Service unavailable if x402.shizu.me is down, returning a 402 or 5xx error
- Empty or zero count if the bazaar index has not yet been populated

## How this service works

The x402 ecosystem thermometer: how many services and resources are listed in the public bazaar right now (cached hourly). Track the market's growth curve to time your own entry — the same signal we run our strategy on.

## Output

Returns the current total count of services and resources listed in the x402 public bazaar, refreshed on an hourly cache. The agent receives a numeric market-size signal indicating how many x402-enabled endpoints are discoverable at time of query.
