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 containing: an array of OHLCV candles (timestamp, open, high, low, close, volume) ordered oldest to newest; the last close price; percentage change over the requested window; EMA20 and EMA50 values; RSI14 value; ATR14 in both absolute and percentage terms; a trend label ('up', 'down', or 'range'); the pullback zone bounds (EMA20 ± 0.75×ATR); and an in_zone boolean indicating whether the current price is within the pullback zone.
Example use cases
BTC trend check before trade entry
“Is BTC currently in an uptrend on the 4-hour chart, and is it pulling back into the EMA20 zone? Give me the RSI14 and ATR as well — I want the last 200 candles.”
ETH momentum scan on 15-minute chart
“Pull the last 50 fifteen-minute candles for ETH and tell me the current RSI14, EMA20, EMA50, and trend direction so I can decide if momentum is building.”
Daily swing setup for altcoins
“Get me 100 daily candles for SOL with EMA20, EMA50, RSI14, ATR, and the pullback zone — I'm looking for a swing trade setup and need to know the trend and whether price is in the zone.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/api/v1/crypto/history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when a trading agent needs OHLCV candlestick data AND precomputed indicators (EMA, RSI, ATR, trend, pullback zone) in a single call, avoiding the need to pull raw candles and compute indicators separately. Ideal for autonomous trading bots, signal generators, and research agents that need a fast, low-cost snapshot of a crypto asset's technical state. Prefer over raw exchange APIs when you want all math done server-side and the response immediately actionable. Best for USDT-quoted major pairs across multiple timeframes.
Side effects
- Invalid or unsupported symbol returns an error — only major USDT pairs (BTC, ETH, SOL, BNB, XRP, DOGE, ADA, AVAX, LINK, SUI, etc.) are supported
- Limit out of range (below 10 or above 500) returns a validation error
- Invalid interval string returns an error — must be one of 1m, 5m, 15m, 1h, 4h, 1d
- Payment failure (x402) if USDC micropayment of $0.002 is not completed
- Upstream data source (Binance) downtime may cause 5xx or stale data responses
