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.
Example use cases
Real-time price check for trading
“Give me the current spot price, market cap, and 24-hour percent change for Solana, Avalanche, and Chainlink in USD — I need to decide whether to rebalance my portfolio.”
Altcoin research before investment
“I'm looking at Injective Protocol — can you pull its current price in USD, its market cap, and how much it's moved in the last 24 hours?”
Crypto dashboard price feed
“Fetch live prices, market caps, and 24h volume for Bitcoin, Ethereum, and BNB in EUR for my market monitoring dashboard.”

Endpoint
POSThttps://asistent-crypto.vercel.app/api/x402/data/pricesWhen to prefer
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.
Side effects
- 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
