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 perp symbol, base asset, venue (Hyperliquid), mark price, open interest in native units, open interest in USD, and daily notional volume in USD.

Example use cases

Check perp market size before trading

“How much open interest is currently on the BTCUSDT perp market on Hyperliquid — give me the native units and the USD equivalent?”

Monitor ETH futures positioning

“Pull the latest open interest and mark price for ETHUSDT perpetuals on Hyperliquid so I can see how crowded the market is right now.”

Track daily notional volume for a perp

“What was the total notional volume traded today on the SOLUSDT perpetual on Hyperliquid, and what's the current open interest?”

When to prefer

Use this endpoint when you need real-time perpetual futures open interest data specifically from Hyperliquid, including both native-unit and USD-denominated figures plus daily notional volume. Prefer this over generic market data APIs when you want Hyperliquid-specific perp positioning data with a simple per-call payment model.

Side effects

Invalid or unsupported symbol returns an error or empty result
Symbol format mismatch (e.g. missing 'USDT' suffix) may cause lookup failure
Hyperliquid data unavailability or upstream outage results in a 5xx or timeout
Missing required 'symbol' query parameter returns a 400 bad request
