## 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-33930a0a -d '<json body>'
```

Example prompt: What's the current spot price, market cap, 24-hour volume, and 24-hour price change for bitcoin and ethereum in USD?

## When to prefer this

Use this endpoint when you need the core price reference data — spot price, market cap, 24h volume, and 24h change — for any cryptocurrency. It is the foundational signal that makes other crypto metrics (funding rates, open interest, dominance, fear & greed) interpretable. Prefer this over generic market APIs when you need pay-per-call access with no account setup, or when operating in an agent context that uses x402 micropayments.

## Known failure modes

- Unknown coin ID returns an error or empty result — only canonical IDs like 'bitcoin', 'ethereum', 'solana' are accepted
- Unsupported quote currency may return an error or null values
- Network or upstream data provider outage may cause stale or missing prices
- Malformed request body returns a validation error

## 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 spot price, market capitalization, 24-hour trading volume, and 24-hour percentage price change for each requested coin, denominated in the specified quote currency.
