## 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-spot-price-market-data-ccdc49ce -d '<json body>'
```

Example prompt: What's the current price, market cap, 24-hour volume, and 24-hour change for Bitcoin and Ethereum in USD right now?

## When to prefer this

Use this endpoint when you need authoritative, real-time spot price data for any cryptocurrency across thousands of coins and any quote currency. It is the foundational price reference — always pair it with funding rate or open interest signals to give those signals context. Prefer this over general web search for price data when you need structured, machine-readable output with market cap and volume in a single call.

## Known failure modes

- Unknown coin ID returns an error or empty result — use the official CoinGecko slug (e.g. 'bitcoin' not 'BTC')
- Unsupported quote currency returns an error
- Rate limiting or upstream data provider outage may cause stale or missing data
- Malformed POST body returns a 400 error
- Payment failure via x402 returns 402 Payment Required

## How this service works

Spot price, market cap, 24h volume and 24h change for any coins by id (bitcoin, ethereum, solana and thousands more), in any quote currency. The reference leg for every other signal here: funding and open interest only mean something next to what price did.

## Output

Returns a structured response per requested coin including: current spot price in the specified quote currency, total market capitalization, 24-hour trading volume, absolute 24-hour price change, and 24-hour percentage change. Serves as the price reference leg for contextualizing other market signals like funding rates or open interest.
