How this service works
Aggregated crypto price feed — top tokens (BTC, ETH, SOL) + stablecoins (USDC, EURC). Paid via x402.
Output
A JSON object keyed by token symbol, where each entry contains the token's current price (in USD), symbol, market cap, 24-hour trading volume, and 24-hour percentage price change. Stablecoins may omit market cap and volume fields.
Example use cases
Portfolio valuation snapshot
“Pull the latest prices and 24-hour changes for BTC, ETH, and SOL so I can see how my crypto portfolio is performing right now.”
Stablecoin peg monitoring
“Check the current prices of USDC and EURC for me — I want to make sure both are holding their pegs.”
Trading signal context
“Get me the current price, 24-hour volume, and price change for ETH and SOL — I need to decide whether to enter a position.”
Technical details
Endpoint
GEThttps://x402.asterpay.io/v2/x402/crypto/prices?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, aggregated price snapshot across the most liquid crypto assets (BTC, ETH, SOL) and major stablecoins (USDC, EURC) in a single call. Prefer it over single-token endpoints when you need multi-asset data in one request, or when you specifically need stablecoin peg data alongside major token prices. The x402 micropayment model makes it cost-effective for per-call agent workflows.
Side effects
- Invalid or unsupported token symbol returns empty or missing key in response
- Payment failure via x402 results in 402 Payment Required response
- Network timeout if upstream price feed is unavailable
- Malformed symbols query parameter may return default token set or error
