Crypto Indicators

by SiteCheck in Onchain & crypto

x402 APIPassing, checked 4 h ago

Technical indicators for one crypto pair and interval, computed from the last 60 to 300 candles: SMA and EMA for the periods you give (default SMA 20, 50, 200; EMA 12, 26), RSI 14 (Wilder), MACD 12/26/9, Bollinger 20/2, ATR 14, the latest values, and a plain trend note (above or below the 200 average, overbought or oversold). Candles come from Coinbase; the newest candle may still be forming. Information only, not financial advice.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.sitecheck-api.workers.dev/api/crypto/indicators?granularity=1h&limit=300&pair=BTC-USD'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://api.sitecheck-api.workers.dev/api/crypto/indicators?granularity=1h&limit=300&pair=BTC-USD' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
