## 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 blocksize-macro-snapshot-c757db0f -d '<json body>'
```

Example prompt: Give me a macro market snapshot right now — I need a broad view of cross-asset conditions, economic indicators, and any key trader signals from Blocksize so I can make a quick decision.

## When to prefer this

Choose this endpoint when you need a holistic, cross-asset macro market overview in a single call rather than individual asset prices. It is ideal for trading agents, portfolio managers, or market briefing workflows that need economic context and multi-asset conditions simultaneously. Prefer this over individual crypto VWAP or FX endpoints when the goal is macro-level situational awareness rather than a specific asset's price.

## Known failure modes

- Payment failure if $1 USDC x402 payment is not included or rejected — returns 402 Payment Required
- Empty or minimal data object if macro data feed is temporarily unavailable
- Malformed request body returns 400 Bad Request
- Service downtime returns 503 or connection error
- Rate limiting if too many calls are made in rapid succession

## How this service works

Find live market data and decision-ready agent workflows: Blocksize provides crypto VWAP, supported equity ticker bid/ask, FX, metals, AMM state prices, VWAP windows, market briefs, macro snapshots, and trader indicators through remote MCP discovery and x402-paid HTTP APIs.
