How this service works
Landing pages ($15), Google Sheets/Apps Script automation ($10), scrapers, scripts & Telegram bots (from $15), broken-link + sitemap audit reports ($10). See a working demo first, pay after.
Output
A JSON object containing an array of price records for each requested coin, each with its CoinGecko ID, symbol, price per quote currency, market cap, 24h volume, 24h percent change, and last-updated timestamp. Also includes the list of quote currencies used, total count, data source (coingecko or coinbase), any tickers not found, and the fetch timestamp. Data is cached for 30 seconds.
Example use cases
Portfolio value snapshot
“Can you pull the current prices for BTC, ETH, SOL, and AERO in USD so I can see how my portfolio is doing today?”
DeFi token contract lookup
“I have this token contract address on Base — 0x940181a94A35A4569E4529A3CDfB74e38FD98631 — can you tell me its current price and 24h change?”
Multi-currency crypto comparison
“Give me the current price of Bitcoin and Ethereum quoted in USD, EUR, and BTC so I can compare across currencies.”
Technical details
Endpoint
GEThttps://quickbuild.quynguyenbac.workers.dev/api/crypto/price?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, near-real-time crypto prices (refreshed every 30 seconds) for up to 25 coins at once across multiple quote currencies. It is especially useful when you need market cap and volume data alongside price, when you want to look up a token by its on-chain contract address across major EVM chains and Solana, or when you need a lightweight one-call solution for bulk crypto quotes without managing CoinGecko API keys. Prefer it over raw CoinGecko calls for its ticker-to-ID resolution, multi-currency output, and built-in Coinbase fallback.
Side effects
- Unknown coin ticker or ID returns 404 with a notFound array listing unresolved symbols
- Invalid input parameters (e.g. malformed address, unsupported chain) return 400
- More than 25 symbols in a single request may be rejected
- More than 5 vs currencies may be rejected
- CoinGecko unavailability triggers fallback to Coinbase spot rates (price only, no market cap or volume)
- Token contract address lookup only supported for one address per call; mixing address with symbols/ids may produce unexpected results
