## 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-pulse-aggregated-crypto-market-data-ec0c41e3
```

Example prompt: Give me a full crypto market snapshot right now — BTC, ETH, SOL, and HYPE spot prices with 24h changes, the Fear & Greed index, Hyperliquid funding rates and open interest, DeFi TVL, and a plain-English summary of what the market is doing.

## When to prefer this

Choose this endpoint when an AI agent needs a comprehensive crypto market snapshot in a single call instead of querying CoinGecko, Fear & Greed API, Hyperliquid, and DefiLlama separately. Ideal for trading dashboards, market briefing bots, or DeFi monitoring workflows that need spot prices, derivatives data, sentiment, and TVL together with a ready-made plain-English summary. Use /v1/spots instead if you only need price data and want to minimize cost.

## Known failure modes

- Upstream provider (CoinGecko, Hyperliquid, DefiLlama) temporarily unavailable — partial data or error returned
- Payment not accepted or x402 USDC on Solana transaction fails — request blocked
- Rate limiting or cache miss during high-traffic period — slightly stale data
- Invalid query parameters — likely ignored since no params are required
- Network timeout to cryptopulseapi.com — connection error returned

## How this service works

One call replaces four for AI agents: CoinGecko BTC/ETH/SOL/HYPE spots + 24h change, Fear & Greed, Hyperliquid funding/mark/OI, DefiLlama TVL/yields, plus a plain-English summary and signals. Keyless upstreams, 60s live cache, x402 USDC on Solana. Free sample GET /v1/sample; MCP POST /mcp.

## Output

A JSON object containing: spot prices (USD + 24h % change) for BTC/ETH/SOL/HYPE from CoinGecko; Fear & Greed index score (0-100) with classification; Hyperliquid perpetual funding rates, mark prices, and open interest for BTC/ETH/SOL/HYPE; DefiLlama total TVL, top chains, and top stablecoin yields; a plain-English one-liner summary; deterministic sentiment label and funding bias signals; a cache metadata object; and an ISO 8601 generatedAt timestamp. Data is cached for up to 60 seconds.
