How this service works
Paid cryptocurrency API endpoints via x402 micropayments
Output
Returns a JSON object with a 'data' field containing the upstream Coinbase API response — typically an array of OHLCV candlestick records for the requested product and time range, including open, high, low, close, and volume values per candle interval.
Example use cases
Crypto trading strategy backtesting
“Get me daily OHLCV candles for ETH-USD from Coinbase for all of 2023 — start January 1st and end December 31st, granularity 86400 — so I can backtest a moving average strategy.”
Real-time crypto price snapshot
“What's the latest price data for SOL-USD from Coinbase right now? Just query the current candle for SOL-USD with a 3600 granularity.”
Portfolio performance analysis
“I need hourly price candles for BTC-USD and MATIC-USD from Coinbase for the past 7 days — start from October 1, 2024 and end October 7, 2024, granularity 3600 — to calculate my portfolio's performance.”
Technical details
Endpoint
POSThttps://x402-crypto.vercel.app/api/coinbase/%7Bpath%7DWhen to prefer
Choose this endpoint when you need historical or current OHLCV candlestick data for a specific Coinbase-listed cryptocurrency trading pair, especially when you want to pay per-call with no subscription using x402 micropayments. Prefer this over scraping or free-tier APIs when you need reliable, Coinbase-sourced market data with flexible granularity for trading analysis or backtesting.
Side effects
- Invalid product ID returns an error or empty data (e.g. typo in BTC-USD)
- Invalid ISO 8601 date format causes a request failure
- Granularity value not supported by Coinbase returns an error
- Time range too large may be truncated or rejected
- Payment failure via x402 results in a 402 response before data is returned
- Missing required 'query' field returns a validation error
