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.
Example use cases
Real-time portfolio valuation
“Pull the current prices, market caps, and 24h changes for bitcoin, ethereum, and solana in USD so I can value my crypto portfolio right now.”
Trading signal context check
“Before I look at funding rates and open interest, grab me the current spot price and 24h performance for ethereum in USDT so I have the price reference.”
Altcoin price monitoring
“What's the current spot price and 24h price change for chainlink in EUR? I want to see if it's moved significantly today.”
Technical details
Endpoint
POSThttps://crypto-asistent.com/api/x402/data/prices?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
