## 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 blockrun-prediction-market-category-metrics-e65d1e5d
```

Example prompt: Can you pull the current category-level metrics for prediction markets on BlockRun — I want to see which categories have the most volume and activity right now?

## When to prefer this

Use this endpoint when you need a high-level overview of prediction market activity segmented by category, rather than individual market details. It is ideal for dashboards, research, or routing logic that needs to understand which sectors are most active. Prefer it over market-level endpoints when you want aggregated, cross-market insights rather than per-market data.

## Known failure modes

- Empty or minimal response if no category data is currently available
- HTTP 402 if payment (USDC via x402) is not properly attached to the request
- HTTP 429 rate limiting if called too frequently
- Stale data if the underlying prediction market data source has not been updated recently
- Schema may return an empty data object if the endpoint is under-populated

## How this service works

Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 115 models and 100 data and tool APIs.

## Output

A JSON object containing aggregated metrics for each prediction market category, likely including fields such as category name, number of markets, total trading volume, liquidity, and activity indicators.
