## 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-market-intelligence-summary-a8b3235a
```

Example prompt: Can you pull the latest x402 market intelligence summary so I can see which API categories are most crowded and which are still wide open — I want the 30-day growth rates too before I decide what to build next?

## When to prefer this

Choose this endpoint when you need a high-level, multi-source view of the x402 API ecosystem before building or investing in a new x402-compatible service. It is the only known aggregated market-intelligence source specifically for x402 discovery data with category-level trend history. Prefer it over manually querying individual x402 discovery directories when you want a single consolidated snapshot with growth rates.

## Known failure modes

- Payment not accepted if wallet lacks USDC on supported networks (Base, Polygon, Arbitrum, Solana)
- Stale data if the aggregation job has not run recently (check as_of_date in response)
- Empty category array if discovery sources are temporarily unreachable
- Rate limiting or 402 payment required errors if payment flow fails

## How this service works

Market-gap analysis for the x402 ecosystem: aggregated, categorized listing counts across x402 discovery sources, plus historical trend data - see how crowded a category is before building a new x402 API. Accepts payment on Base, Polygon, Arbitrum, and Solana (USDC) - pick whichever network your wallet holds funds on.

## Output

A JSON object with an as_of_date timestamp and an array of category objects, each containing the category name, total listing count, and 30-day growth percentage — giving a current and trending view of how populated each x402 API category is.
