How this service works
Paid funding rates and funding arbitrage decision API for AI trading agents across 18 perp venues. Settled via x402 on Base mainnet (eip155:8453) using the Coinbase Mogami v2 facilitator; unpaid requests receive a 402 challenge that lists the per-route price.
Output
A structured object containing per-venue funding rate records (rate, interval hours, funding kind, next funding time), a plain-language summary string, the venue with the highest and lowest annualized rate, the raw annualized spread and per-interval spread, and metadata including timestamp and source. Covers up to 16 venues including Binance, Bybit, Hyperliquid, Paradex, Backpack, and more.
Example use cases
Example prompt
“What are the current funding rates for BTC across all supported perp venues — and which venue has the highest vs lowest annualized rate right now?”
Technical details
Endpoint
GEThttps://funding-rates-x402.data-labs.cloud/v1/funding/summary/%7Bsymbol%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI trading agent needs to compare funding rates across a broad set of centralized and decentralized perp venues in a single call. It is especially useful for funding rate arbitrage detection, venue selection for minimizing carry costs, or any workflow that needs both raw per-interval rates and pre-computed annualized spreads. Prefer this over venue-specific APIs when multi-venue breadth matters.
Side effects
- 402 Payment Required — no valid MPP payment receipt attached; response body lists per-route price in USDC
- Unknown or unsupported symbol — may return empty records array or error
- Invalid venues parameter format — comma-separated list expected; malformed input may yield partial or no results
- Venue data unavailable — a specific venue may be missing from records if it is temporarily unreachable
- Rate limiting or infrastructure errors — 5xx responses if upstream data provider is down
