How this service works
Live crypto spot-price snapshots (USD) and fiat FX spot rates. Pay-per-request via x402 v2: $0.01 USDC on Base, Monad, Arbitrum, Optimism, Polygon, Avalanche or Solana (eip155:8453), Monad (eip155:143), Arbitrum (eip155:42161), Optimism (eip155:10), Polygon (eip155:137), Avalanche (eip155:43114) or Solana, scheme exact (EIP-3009). Unpaid calls return HTTP 402 with a base64 PAYMENT-REQUIRED header; retry with a PAYMENT-SIGNATURE header.
Output
A JSON object containing a Unix timestamp (as_of), an array of per-asset results each with ok status and either price data or an error message, the service name ('bulk'), the USDC price charged, and counts of ops requested vs succeeded.
Example use cases
Portfolio value snapshot
“I need the current USD spot prices for BTC, ETH, SOL, and AVAX all at once so I can calculate my portfolio's total value.”
FX rate lookup for invoice conversion
“What's the live exchange rate between USD and EUR right now? I need to convert a $5,000 invoice to euros.”
Crypto arbitrage price check
“Can you grab real-time spot prices for Bitcoin and Ethereum across both their USD pairs so I can check if there's an arbitrage opportunity?”
Technical details
Endpoint
POSThttps://x402-spot-prices.hsharmanov02.workers.dev/bulk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live spot prices for multiple crypto assets or fiat pairs in a single low-latency call and are comfortable with x402 micropayment authentication ($0.01 USDC per call). It is ideal for agents that need real-time price data without a subscription, paying only per use. Prefer alternatives if you need historical price data, order book depth, or OHLCV candlestick data.
Side effects
- HTTP 402 returned if no payment signature is provided — must retry with PAYMENT-SIGNATURE header
- Individual asset lookups within the bulk response may return ok:false with an error string if the data source is unavailable
- Invalid or unsupported asset symbols return an error entry in the results array rather than rejecting the whole request
- Network timeout if Cloudflare Worker is under high load
