## 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 agentflare-ethereum-data-feed-d8c88513
```

Example prompt: Can you pull the latest Ethereum market and blockchain data from AgentFlare right now so I can see current ETH stats?

## When to prefer this

Choose this endpoint when you need structured, agent-ready Ethereum data served via the x402 micropayment protocol — ideal for AI agents that need to programmatically fetch ETH market or blockchain data without managing API keys, subscriptions, or OAuth flows. Prefer this over generic crypto APIs when operating in an agentic context with native payment capabilities.

## Known failure modes

- Payment not provided or failed (402 Payment Required — x402 micropayment of $0.01 USDC must be included)
- Network timeout if Ethereum data source is temporarily unavailable
- Malformed JSON response if upstream data provider is degraded
- Rate limiting if too many requests are sent in a short period

## Output

A structured JSON object containing live Ethereum data including price, market metrics, and blockchain statistics, returned as application/json.
