How this service works
The insurance booth for AI agents, with Mini's Agent Supply Store on the side of the road. One hundred checkpoints: pre-transaction safety lanes (honeypot, approval-risk, rug-score, receipt-check, tx-dryrun, permit-scan, airdrop-verdict, deployer-history, wallet-watch, secret-scan at $0.02 USDC per call; the protection tier — /contract-check, /approval-screen, /tx-plain-english, /honeypot-check, /tx-simulate, /redteam, /skill-scan, /verdict, /egress-audit, /tool-gate, /airlock, /repo-scan, /prove, /task-scope — at $0.10; the one-call /shield don't-get-rugged screen at $0.25; the full /preflight bundle at $0.05), bounty intel (bounties, fresh, verdicts, deadlines, sweepstakes, opportunities) at $0.02 USDC per call, trader intel (/prices and /quant at $0.02; /enrich and /token-check at $0.05; /contract-check and /honeypot-check at $0.10; /sec-facts at $0.05), market intel (/markets and /search at $0.05; /grants at $0.02), DeFi intel (/yields and /new-pairs at $0.05; /gas and /defi at $0.02), AI intel (/models at $0.02), agent-ops intel (/prompt-cost, /model-picks, /rpc-speed, /terms-tldr, /scrape, /gigs, /retry-verify, /idempotency, /verify-independent at $0.02; /site-watch, /wallet-check, /code-run, /regulatory-pack, /sage, /cron-watch, /caveat-check, /tripwire, /escrow, /trust, /bridge-fees, /dao-votes, /dev-activity, /dex-arb, /dydx-perps, /funding-rates, /gas-predict, /hack-tracker, /long-short-ratio, /lp-yields, /mev-scan, /open-interest, /perp-basis, /polymarket-odds, /rwa-watch, /sentiment, /stablecoin-flows, /tokenomics, /top-movers, /whale-watch, and /yield-stable at $0.05; /approval-screen, /tx-plain-english, /tx-simulate, and /task-scope at $0.10; /scam-scan deep scan at $5.00 or 30-day subscription at $30.00), supply store (/road-pack combo meal at $0.05; curated datasets, the /audit-prep pre-audit review, and the /prove-state symbolic-execution run at $1.00; the /audit AI-agent audit at $25.00). Every lane answers before money moves — heuristic verdicts, not audits. Don't get rugged.
Output
Returns a JSON object with the base asset, venue (Hyperliquid), mark price, oracle price, raw premium, basis in basis points, funding rate per hour, annualized funding APR percentage, and maximum available leverage for the queried perpetual symbol.
Example use cases
Funding rate arbitrage screening
“Check the perp basis for ETHUSDT on Hyperliquid — I want to see the premium in bps and the annualized funding rate so I can decide if there's a cash-and-carry arb worth running.”
Position cost monitoring
“What's the current hourly funding rate for BTCUSDT perps? I have a long position and want to know how much I'm paying in funding right now and what that works out to annually.”
Market sentiment gauge via basis
“Is the BTCUSDT perp mark price trading at a premium or discount to the oracle price on Hyperliquid right now, and by how many basis points? I want to gauge market sentiment.”
Technical details
Endpoint
GEThttps://mini-tollbooth.onrender.com/perp-basis?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time perpetual futures basis and funding rate data specifically from Hyperliquid, particularly for cash-and-carry arbitrage analysis, monitoring funding cost on open positions, or gauging market sentiment via the mark-oracle spread. Prefer this over generic market data APIs when Hyperliquid-specific data is required and when funding APR and basis bps are needed in a single call.
Side effects
- Invalid or unsupported symbol returns an error — use formats like 'BTCUSDT' or 'ETHUSDT'
- Hyperliquid data feed unavailability may cause stale or missing data
- Missing required 'symbol' query parameter returns a 400-level error
- Network timeout from Hyperliquid upstream causes delayed or failed response
