How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
A JSON response listing perpetual markets traded on both Hyperliquid and dYdX v4, each with mark price, hourly and annualized funding rates, 24h volume, open interest per venue, and the computed funding spread (Hyperliquid minus dYdX) in both hourly and annualized percentage terms. Results are sorted by absolute annualized spread descending. Also includes source metadata, cache status, total count of markets on both venues, and data disclaimers.
Example use cases
Funding rate arbitrage opportunity scanner
“Find the top 10 crypto perpetuals with the largest funding rate spread between Hyperliquid and dYdX — I want to see both the hourly and annualized spread, and only include markets with at least $5 million in daily volume.”
ETH and BTC funding cost comparison
“Compare the current funding rates for BTC and ETH specifically on Hyperliquid vs dYdX — I need the hourly and annualized rates for each, and which exchange is paying more right now.”
Carry trade monitoring for portfolio
“Give me the 20 perpetual markets with the highest absolute funding spread between Hyperliquid and dYdX, regardless of direction, with no minimum volume filter — I'm looking for carry trade ideas across all liquid pairs.”
Technical details
Endpoint
POSThttps://tanod.dev/v1/defi/funding-spread?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to compare perpetual futures funding rates specifically between Hyperliquid and dYdX v4, particularly for identifying cross-exchange funding rate arbitrage or carry trade opportunities. Prefer this over single-exchange funding rate lookups when the spread between venues is the primary signal of interest.
Side effects
- Symbol not found on one or both venues — returned in symbols_not_found array
- All requested symbols filtered out by min_volume_usd — empty markets array returned
- Upstream API unavailability (Hyperliquid or dYdX indexer down) — may return stale cached data or error
- Invalid symbol format — rejected by pattern validation
- limit out of range (outside 1-50) — validation error
