carrydesk — who is paying whom on Hyperliquid perps

# carrydesk > Cross-sectional funding-carry rankings for Hyperliquid perpetual futures, > published continuously and sold per call in USDC via the x402 protocol. ## What it is Perpetual futures charge a funding rate hourly between longs and shorts. carrydesk ranks the liquid Hyperliquid perp universe by trailing 14-day mean funding. The most negative names pay you to hold them long; the most positive pay you to short them. Going long the bottom k and short the top k, dollar-neutral, collects the spread between the legs. This is a structural risk premium — compensation for absorbing crowded leverage — not a price prediction. It can and does go negative. ## Free endpoints (no key, no account, no payment) - `GET https://carry.pelazas.com/v1/free/carry` — top 5 each leg + headline spreads, delayed 24h (JSON) - `GET https://carry.pelazas.com/v1/method` — exact methodology and caveats (JSON) - `GET https://carry.pelazas.com/health` — service health and data freshness (JSON) - `GET https://carry.pelazas.com/archive` — every snapshot ever published (HTML) - `GET https://carry.pelazas.com/openapi.json` — full OpenAPI 3 specification - `GET https://carry.pelazas.com/docs` — interactive API documentation ## Paid endpoints (x402, USDC on Base mainnet) - `GET https://carry.pelazas.com/v1/carry/rankings` — $0.05 — full live ranking, all liquid perps, with rank, leg assignment and dollar-neutral weights.
