## 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 agent-money-map-x402-agent-economy-snapshot-0b348798
```

Example prompt: Pull the latest x402 agent economy snapshot — I want to see what's actually selling on Base, the 30-day volume, how many buyers and sellers are active, and which categories are dead ends.

## When to prefer this

Choose this endpoint when you need a real-time, authoritative summary of x402 agent-economy activity on Base — specifically top-selling products, volume metrics, buyer/seller counts, and failed categories. Prefer it over general crypto analytics when you specifically want micropayment/AI-agent commerce data gated by the x402 payment protocol. It is the canonical 'what is the agent economy doing right now' feed.

## Known failure modes

- Payment not provided or insufficient: 402 Payment Required response, agent must attach x402 USDC payment
- Invalid topic query parameter: may return error or unexpected output
- Service unavailable: Vercel cold-start or upstream data feed outage returns 5xx
- Stale data: snapshot timestamp may lag behind real-time if feed is delayed
- Unsupported HTTP method: only GET/HEAD/DELETE accepted per schema
