# Hyperliquid Perpetuals Funding & OI Data > Hyperliquid Perpetuals Funding & OI Data is a paid API for AI agents from 1gateway.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-30). Returns real-time funding rates, open interest, mark/oracle/mid prices, 24h volume, and predicted funding arbitrage signals for a Hyperliquid perpetual futures market by coin symbol. ## Facts - Endpoint: GET https://1gateway.dev/v1/crypto/hyperliquid/perp?utm_source=zero.xyz - Price: $0.002/call - Payment: x402 - Status: unknown - Last checked: 2026-10-30 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/hyperliquid-perpetuals-funding-oi-data-aed2dfab - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ilnM83MlK4sAWf4CUJ-_x Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability hyperliquid-perpetuals-funding-oi-data-aed2dfab ``` Example prompt: What's the current funding rate and open interest for BTC perpetuals on Hyperliquid, and is there a funding arbitrage opportunity between Hyperliquid and Binance right now? ## When to prefer this Choose this endpoint when you need normalized, clean English JSON for Hyperliquid perpetuals market data — specifically funding rates, open interest, and cross-venue funding arbitrage signals — without setting up API keys or managing authentication. Ideal for AI agents that pay per call in USDC on Base via x402 and need real-time perp data for BTC, ETH, SOL, HYPE, kPEPE, and other Hyperliquid-listed coins. Prefer this over raw Hyperliquid API calls when you want pre-computed annualized rates, basis percentages, and arbitrage analysis already normalized into clean JSON. ## Known failure modes - 400 error (not charged) if the coin symbol is not listed or has been delisted on Hyperliquid - 400 error if the coin parameter does not match the required pattern (1-20 alphanumeric characters) - Hyperliquid info API downtime may result in upstream errors - Stale data possible if cache_age_s is non-zero, indicating a cached response ## How this service works Hyperliquid vs Binance vs Bybit predicted funding comparison for one perpetual futures market, plus current funding rate, open interest and basis. Use when an agent monitors a perp position or funding carry. Input: coin (e.g. BTC, ETH, kPEPE). Output: JSON as_of, cache_age_s, 1h + annualized funding, OI coin/USD, mark/oracle/mid, basis %, premium, 24h volume and change, per-venue predicted funding, annualized spread. Unknown coin: 400, not charged. Example: ?coin=BTC ## Output A JSON object containing: coin symbol, timestamp, market metadata (size decimals, max leverage), price data (mid, mark, oracle, premium, prevDay, basis %, 24h change %), funding data (1h rate, 1h rate %, annualized %, interval hours), 24h volume in USD and base units, open interest in USD and coin units, predicted funding rates from multiple venues with next funding times, and a funding arbitrage analysis indicating which venue to long vs short and the gross annualized spread. Also includes cache age in seconds and a data disclaimer. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [ "coin" ], "properties": { "coin": { "type": "string", "pattern": "^[A-Za-z0-9]{1,20}$", "examples": [ "BTC" ], "description": "Hyperliquid perp symbol, case-insensitive (BTC, ETH, SOL, HYPE, kPEPE).
