## 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-price-feed-fd151f07
```

Example prompt: What's the live USD price of ETH right now — pull it from Binance, Coinbase, and CoinGecko and show me the spread between venues and the 24h change.

## When to prefer this

Choose this endpoint when you need real-time, multi-venue USD crypto prices without API keys or account setup, especially when cross-venue price comparison, spread analysis, or weighted average pricing is needed. Prefer over single-source price APIs when arbitrage detection or price reliability validation across venues matters. Ideal for agents needing quick, keyless crypto price lookups for any token.

## Known failure modes

- Unknown or delisted symbol returns an error or null prices for one or more venues
- One venue temporarily unavailable causes partial data with that venue omitted or nulled
- Highly illiquid token may have no data on some venues
- Rate limits from upstream public exchange APIs may cause intermittent failures
- Malformed symbol input returns a validation error

## How this service works

Crypto price API - the live USD price of any cryptocurrency from three independent keyless venues (Binance, Coinbase, CoinGecko), with the 24h change, the high and low, the weighted average, the quote volume and the cross-venue SPREAD. GET ?symbol=<SYMBOL> OR ?symbols=<A,B,C> OR ?sample=1|2|3 OR POST application/json {symbol|symbols}. KEYLESS public exchange endpoints - no key, no account, no signup. Returns the price per venue, the median, the spread between the highest and lowest venue and...

## Output

A JSON response containing per-venue USD prices (Binance, Coinbase, CoinGecko), the median price, weighted average price, 24h percentage change, 24h high and low, quote volume per venue, and the cross-venue spread (difference between highest and lowest venue price).
