How this service works
Pay-per-call data API: crypto prices (CoinGecko), China A-share quotes (Sina), weather (Open-Meteo), forex rates, and Ethereum gas fees. Payments via x402 protocol, USDC on Base.
Output
Returns a JSON object with a Unix millisecond timestamp, individual USD prices for each requested cryptocurrency (e.g. BTC, ETH, SOL), and the source identifier ('coingecko').
Example use cases
Portfolio value snapshot
“Pull the current prices for BTC, ETH, and SOL right now so I can calculate my crypto portfolio's total value.”
Trading bot price refresh
“Fetch the latest CoinGecko prices for BTC and ETH in a single batch call — I need both prices timestamped so my bot can decide whether to rebalance.”
Crypto dashboard data feed
“Get me real-time prices for BTC, ETH, and SOL to populate my dashboard. I want all three in one request with a timestamp.”

Endpoint
POSThttps://x402-api-blond.vercel.app/crypto/batchWhen to prefer
Choose this endpoint when you need real-time prices for multiple cryptocurrencies in a single low-latency call and are operating in an x402-compatible payment environment with USDC on Base. It is ideal for agents that need CoinGecko-sourced data with pay-per-call economics, avoiding subscription overhead for infrequent price checks.
Side effects
- Payment failure if USDC wallet lacks sufficient balance (402 error)
- Invalid or unsupported cryptocurrency symbols return empty or error fields
- CoinGecko upstream outage causes stale or missing price data
- Malformed MCP input schema results in 400 validation error
- Rate limiting from CoinGecko may cause delayed or failed responses
