How this service works
One-call crypto market regime for trading agents: BTC/ETH/SOL median spot + 24h change, Hyperliquid funding APR + open interest, Korea kimchi premium, Crypto Fear & Greed index, and a regime label (risk_on|neutral|risk_off) with plain reasons. Replaces 4 calls (prices+hl-funding+kimchi+sentiment, $0.015) for $0.004.
Output
A JSON object containing: per-asset spot prices (BTC/ETH/SOL) and 24h change percentages; Hyperliquid funding APR and open interest per asset; Korea kimchi premium percentage; Fear & Greed index numeric value and label; a regime string (risk_on, neutral, or risk_off); an array of plain-English reason strings explaining the regime; and an ISO 8601 updated_at timestamp.
Example use cases
Automated trading position sizing
“Before my DeFi agent opens a new BTC long position, check whether the market is currently risk-on or risk-off, and tell me the BTC funding APR on Hyperliquid and the Fear & Greed score so I can size it correctly.”
Morning crypto briefing for a portfolio manager
“Give me a quick crypto market pulse — BTC, ETH, and SOL prices with their 24-hour changes, the current Fear & Greed reading, and whether the regime is risk-on or risk-off right now.”
Korea arbitrage opportunity scan
“Check the current kimchi premium on BTC between Korean and global markets, and include the broader market regime signal so I can decide whether to act on any spread.”

Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/crypto/market-pulse?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs a single aggregated crypto market signal instead of making 4+ separate API calls for prices, funding rates, kimchi premium, and sentiment. At $0.004 per call it is significantly cheaper than assembling the same data from individual sources ($0.015+). Ideal for high-frequency trading agents, position-sizing logic, or any workflow that needs a quick regime check before executing on-chain actions.
Side effects
- Upstream data source unavailable — stale or missing price/funding data returned
- Payment not settled via x402 — 402 Payment Required response
- Network timeout from Cloudflare Worker — 504 or empty response
- Kimchi premium unavailable if Korean exchange API is down
- Fear & Greed index missing if Alternative.me is unreachable
