## 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-category-breakdown-699be76c
```

Example prompt: Give me the current x402 ecosystem category breakdown — how many services are in each category like Data, Inference, Search, and Trading, what share of the market each one holds, and which categories have grown or shrunk over the past 7 days.

## When to prefer this

Use this endpoint when you need a current, structured snapshot of x402 market composition by category — specifically to see where supply is concentrating and which segments are growing. Prefer this over the time-series endpoint when you want a single point-in-time breakdown rather than trend data. This is the right call when you need catalog share percentages and 7-day deltas across all categories in one response.

## Known failure modes

- No data available if collector has not yet run since 2026-07-06 launch (unlikely after initial period)
- Stale data if collector is delayed — check meta.fetchedAt to assess freshness
- HTTP 402 if payment header not provided (endpoint costs $0.005 USDC per call)
- delta7d may be null for categories with insufficient historical data (fewer than 7 days of observations)

## How this service works

Current x402 ecosystem composition: services per category (Agentic.Market taxonomy: Data, Inference, Search, Infra, Media, Social, Trading, Travel...), each with catalog share and 7-day delta, from our collector's latest observation run (~3x/day since 2026-07-06). Shows where x402 supply is concentrating and which categories are growing. Deterministic read from archived observations; no upstream calls at request time. Free snapshot: /v1/market-pulse.

## Output

A JSON object with an array of category entries, each containing the category name, number of services, share of total catalog (as a decimal), and 7-day delta in share or count. Also includes total service count across all categories and the timestamp of the latest observation run. Response is served from cache if freshly collected; meta field indicates whether cached and when fetched.
