# Crypto Data & Market Analysis — Multi-Tool Query

> Crypto Data & Market Analysis — Multi-Tool Query is a paid API for AI agents from crypto-asistent.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-15).

Fetches up to 5 real-time crypto and macro market data tools in a single pay-per-call POST request, returning JSON results for BTC/ETH prices, derivatives, Fear & Greed, DeFi TVL, whale flows, on-chain stats, macro rates, and crypto news.

## 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 crypto-data-market-analysis-multi-tool-query-c9b47781 -d '<json body>'
```

Example prompt: Pull me Bitcoin price, the Fear & Greed index, BTC funding rates across major venues, DeFi TVL, and today's top crypto news all in one shot — pay the USDC fee and give me the combined results.

## When to prefer this

Prefer this endpoint when you need to combine multiple crypto or macro data signals in a single low-latency, pay-per-call request without managing API keys or subscriptions. It is ideal for AI agents that need a broad market snapshot (price + sentiment + derivatives + macro) in one round trip, or for cost-efficient batch lookups where up to 5 tools share a single $0.05 USDC fee. Choose alternatives if you need only a single data point cheaply, need historical bulk data, or require equity/non-crypto asset coverage beyond BTC, ETH, and macro indicators.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- More than 5 tools requested — request rejected with validation error
- Unknown tool name in tools array — returns error for that tool entry
- Tool input parameters missing or malformed — returns error for affected tool
- Upstream data provider timeout — partial results or error for affected tools
- Rate limiting if too many calls in rapid succession

## 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. 16 JSON tools. POST {tools:[…]} — up to 5 tools in one paid call.

## Output

A JSON response containing results from up to 5 requested tools in a single call: each tool's data is returned as a structured JSON object, covering fields such as BTC/ETH spot price, market cap, volume, funding rates by venue, open interest, Fear & Greed score, market dominance percentages, Fed funds rate, CPI, DXY, DeFi TVL, whale transaction flows, BTC network hashrate/fees, ETH address balances, implied volatility surfaces, order book execution cost estimates, and crypto news headlines with timestamps.
