## 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 asistent-crypto-macro-6e14adaf -d '<json body>'
```

Example prompt: Can you pull the current crypto fear and greed index for me, and also grab the latest BTC network stats and market dominance data?

## When to prefer this

Choose this endpoint when you need live, unified crypto and macro data from a single API — especially when you want fear/greed sentiment, on-chain BTC/ETH metrics, derivatives, DeFi overview, or economic calendar data without stitching together multiple providers. It is particularly valuable for agents that need a breadth of crypto-native and macro signals in one call with a simple tool-dispatch pattern.

## Known failure modes

- Invalid or missing 'tool' enum value returns an error response
- Upstream data provider unavailability may cause empty or stale data
- Malformed body or missing required fields returns a validation error
- Payment failure or insufficient USDC balance blocks the call
- Rate limiting or server errors on the Vercel deployment may cause timeouts

## How this service works

Real-time crypto & macro market data for AI agents, pay-per-call in USDC (no account or API key): Bitcoin (BTC) and Ethereum (ETH) prices, funding rates, open interest, Fear & Greed index, market dominance, macro rates (Fed, CPI, DXY), DeFi TVL, whale flows, on-chain stats, crypto news. 13 JSON tools. POST {tool, input}.

## Output

A JSON object with ok: true, a tool field echoing the requested tool name, and a data object containing the live result specific to that tool — e.g. {value: 20, classification: 'Extreme Fear'} for fear/greed, or structured market/network/rates/news objects for other tools.
