How this service works
Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.
Output
Returns a JSON object with: array of OHLCV candles (open, high, low, close, volume, timestamp), last price, percent change, candle count, interval, symbol, data source, and a pre-computed indicators block containing RSI14, EMA20, EMA50, ATR14, ATR14 as percent of price, trend direction (up/down/sideways), and a support/resistance zone with low/high bounds and an in-zone boolean. Updated timestamp included.
Example use cases
Momentum check before placing trade
“Pull the last 50 four-hour candles for ETH and tell me whether RSI is overbought, what the EMA20 vs EMA50 crossover looks like, and whether the current price is in a support or resistance zone.”
Scalping bot signal feed
“Give me the last 200 one-minute candles for SOLUSDT so my scalping bot can compute entry signals — include ATR for stop-loss sizing and trend direction.”
Daily swing trade review
“Fetch 100 daily candles for BTC with all the technical indicators — I want to see the 14-day RSI, ATR as a percent of price, and whether we're trending up or down before I set my swing trade for tomorrow.”

Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/api/crypto-candles?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs candlestick market data AND pre-computed technical indicators (RSI, EMA, ATR, trend, zones) in a single call without managing API keys. Ideal for trading bots, onchain AI agents, or signal generators that need fast, pay-per-use access to structured OHLCV + indicator data. Prefer over raw exchange APIs when you want indicators pre-calculated server-side. Use over generic market data APIs when you need x402 micropayment compatibility and no subscription overhead.
Side effects
- Unknown symbol returns error or empty candles array
- Interval not in allowed enum causes 400 validation error
- Limit outside 10-500 range returns validation error
- Payment not included or insufficient USDC triggers 402 response requiring x402 payment
- Binance data source temporarily unavailable causes 5xx or stale data
