How this service works
Look up current price, 24h change, and market cap for one or more cryptocurrencies
Output
A JSON object keyed by CoinGecko coin ID, each containing the current price in the requested quote currency, the 24-hour percentage change, and the market cap. Data is fetched live from CoinGecko and reflects real-time market conditions.
Example use cases

Euro-denominated price check
“What's the current price and 24-hour change for bitcoin quoted in euros?”
Altcoin price monitor

Technical details
Endpoint
GEThttps://agentx402pay.com/api/crypto-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, low-cost real-time price check with 24h change and market cap for one or more coins. Prefer the sibling 'x402 Crypto Market Data' endpoint when you need richer data such as 24h high/low, trading volume, all-time-high, or rank. This endpoint is ideal for quick portfolio checks, price alerts, or feeding current prices into downstream computations.
Side effects
- Invalid or misspelled CoinGecko coin ID returns empty result or error
- Unsupported quote currency falls back to USD or returns an error
- Missing required 'ids' query parameter causes a 400 bad request
- Network or upstream CoinGecko outage may cause 500 or timeout
- Payment failure (insufficient USDC balance) blocks the request via x402 protocol
