## 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 terminalfeed-io-c6727040
```

Example prompt: Pull the morning briefing so I have today's Bitcoin price and volume, the Fear & Greed Index, latest earthquake summary, Hacker News top stories, current ISS crew, and highest-volume Polymarket markets all at once.

## When to prefer this

Choose this endpoint when an AI agent needs to bootstrap with current world context at startup and wants to minimize network round trips. Ideal for agents that need crypto market sentiment, breaking science/geopolitical signals, tech news pulse, and prediction market data simultaneously without chaining multiple specialized APIs. Best when cost-per-call efficiency ($0.02 for 7+ data sources) matters more than granular control over individual data sources.

## Known failure modes

- Payment not included or invalid x402 payment header — returns 402 Payment Required
- Upstream data source (USGS, Polymarket, etc.) temporarily unavailable — may return partial data or 503
- Rate limit exceeded — returns 429 Too Many Requests
- Malformed request or unsupported query parameters — returns 400 Bad Request

## How this service works

Agent morning brief. One paid call composes Bitcoin spot + 24h volume, the Crypto Fear & Greed Index, the latest USGS earthquake summary, top-story counts from Hacker News, current ISS crew, and the highest-volume Polymarket prediction markets. The endpoint an agent calls on boot to get the day's context in one network round trip.

## Output

A single JSON object containing: current Bitcoin spot price and 24-hour trading volume, the Crypto Fear & Greed Index value and label, a USGS earthquake summary, Hacker News top-story count, current ISS crew list, and the highest-volume active Polymarket prediction markets — all from one network round trip.
