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.

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).
Example use cases
Arbitrage spread monitoring
“Check the current price of BTC across Binance, Coinbase, and CoinGecko and tell me what the spread is between the highest and lowest venue — I want to know if there's a meaningful arbitrage gap right now.”
Portfolio snapshot pricing
“Get me the live USD prices for BTC, ETH, and SOL all at once, including the 24h change and weighted average for each, so I can update my portfolio valuation.”
Token price sanity check before trade
“Before I place a trade, what's the current live USD price of LINK across the three major venues, and what's the 24h high and low so I can see where it's trading relative to today's range?”
Technical details
Endpoint
GEThttps://6xrkjcfa3yrzvefcpvanurzou4.srv.us/api/crypto/price-feed?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
