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: last price, symbol, interval, number of candles, percent change, source exchange (Binance), array of OHLCV candles, and a nested indicators object containing EMA20, EMA50, RSI14, ATR14, ATR14 as percentage, trend direction (up/down/sideways), and a support/resistance zone (low, high, in_zone boolean). Also includes an updated_at timestamp.
Example use cases
Momentum check before trade entry
“What's the current RSI and EMA trend for ETH on the 4-hour chart over 200 candles — is it overbought or in a bullish uptrend?”
Support zone detection for stop-loss placement
“Fetch the ATR and support/resistance zone for SOL on the 1-hour timeframe so I can figure out where to set my stop-loss.”
Automated trading signal generation
“Get me the EMA20, EMA50, RSI14, and trend direction for BTCUSDT on the 15-minute chart with 100 candles so my trading bot can decide whether to buy or hold.”

Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/v1/indicators/ema?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI trading agent needs lightweight, pay-per-call technical indicator data (EMA, RSI, ATR, trend) without API key setup, especially in automated or low-volume agentic workflows where a subscription model is wasteful. Ideal for agents already operating on Base/USDC via x402. Prefer over full-service charting APIs when you only need computed indicators and recent candlestick data for a single symbol.
Side effects
- Invalid symbol returns an error or empty data
- Interval not in allowed enum (1m,5m,15m,1h,4h,1d) returns a 400 error
- Limit outside 10-500 range returns a validation error
- Payment failure or insufficient USDC balance returns 402 Payment Required
- Binance data source downtime may cause stale or missing candle data
