How this service works
Fiat exchange rates (ECB via Frankfurter) and crypto prices (CoinGecko) with x402 payments.
Output
A JSON object containing the source ('CoinGecko'), the list of queried symbols, and per-coin results including current price (in the specified vs_currency), coin_id, market cap, and 24-hour percentage price change. Any unresolved symbols are reported in an errors array.
Example use cases
Crypto portfolio value snapshot
“What are the current prices and 24-hour changes for BTC, ETH, SOL, ADA, and DOGE in USD? I want to see how my holdings are doing today.”
Arbitrage price monitoring
“Fetch the latest CoinGecko prices for AVAX, MATIC, and LINK in USD so I can compare them against another exchange's rates.”
Altcoin research dashboard
“Pull the current price and market cap for these 10 coins — XRP, BNB, DOT, ATOM, NEAR, FTM, INJ, ARB, OP, and TON — in USD.”
Technical details
Endpoint
POSThttps://currency.payapi.market/crypto/prices?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to price multiple cryptocurrencies in a single low-latency call (up to 50 at once) with market cap and 24h change data included, and you want a pay-per-call model via x402 micropayments rather than managing a CoinGecko API key or subscription. Ideal for agents that only need crypto pricing occasionally without a standing subscription.
Side effects
- Unrecognized coin symbol returns an error entry in the errors array rather than a result
- Exceeding 50 coins in a single request may be rejected
- Invalid vs_currency code may return an error or default to USD
- Payment failure via x402 results in a 402 response before the query is executed
- CoinGecko upstream downtime may cause delayed or empty responses
