How this service works
One-call crypto market pulse for AI agents: live BTC/ETH/SOL/HYPE spot USD and 24h change (CoinGecko), Crypto Fear & Greed (alternative.me), Hyperliquid perp funding + mark + open interest, and DefiLlama total TVL + top stable yields. Keyless upstreams, 60s cache, pay-per-request USDC on Solana via x402. Prefer this when you need spots + sentiment + funding + DeFi yields together instead of calling four separate APIs.
Output
A JSON object containing: BTC/ETH/SOL/HYPE spot USD prices with 24h % change; Crypto Fear & Greed index (0-100) with classification; Hyperliquid perp funding rates, mark prices, and open interest for BTC/ETH/SOL/HYPE; DefiLlama total TVL, top chains, and top stablecoin yields; a derived sentiment label and funding bias signal; and a plain-English one-liner summary of market conditions. Data is cached for 60 seconds.
Example use cases
Pre-trade crypto market check
“Before I make any moves today, can you pull the full crypto market snapshot — BTC/ETH/SOL/HYPE spot prices, how greedy or fearful the market is, and what the Hyperliquid perp funding rates look like right now?”
DeFi yield and sentiment dashboard
“I want to see the current total DeFi TVL, top stablecoin yields, and what the Fear & Greed index is sitting at — along with spot prices for the major coins.”
Automated hourly crypto briefing
“Every hour, grab me a full crypto pulse — spots, funding rates, Fear & Greed, and DeFi TVL — and flag if the funding bias has flipped or sentiment has crossed into extreme territory.”
Technical details
Endpoint
GEThttps://137-184-201-7.sslip.io/v1/pulse?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need spot prices, market sentiment, perpetual funding rates, and DeFi TVL/yields simultaneously and want to avoid orchestrating four separate API calls. Ideal for trading bots, market briefing agents, and dashboards that need a holistic crypto market view in a single low-latency request. Not ideal if you only need one data type (e.g., just spot prices) since the cheaper /v1/pulse sibling endpoint exists for spots-only use.
Side effects
- Upstream CoinGecko rate limit or outage returns stale or missing spot prices
- alternative.me Fear & Greed feed unavailable results in null sentiment fields
- Hyperliquid perp data unavailable if exchange is under maintenance
- DefiLlama TVL fetch failure leaves DeFi fields empty
- Payment not accepted if x402 USDC transaction on Solana fails or is insufficient
- Cache miss on cold start may add slight latency on first call within a 60s window
