## 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

```

Example prompt: Give me the current Hyperliquid perpetuals market brief — I want to see BTC funding rates, open interest, whale net positioning, and the nearest whale liquidation levels in one summary.

## When to prefer this

Choose this endpoint when you need a single comprehensive Hyperliquid perps market snapshot for an AI agent or trading bot — it combines funding extremes, whale positioning, liquidation levels, and major asset summaries in one LLM-ready call. Prefer it over building separate API calls to Hyperliquid's public endpoints when you want pre-aggregated, agent-optimized output with freshness guarantees and a low per-call cost ($0.008 USDC).

## Known failure modes

- Data too stale — endpoint returns age warning or withholds charge
- Payment not received via x402 — returns 402 Payment Required
- Hyperliquid public data temporarily unavailable — may return partial or cached data
- Rate limiting if called too frequently without valid payment

## How this service works

Paid token safety / rug-pull checks for AI agents: Solana SPL (/check) and Robinhood Chain ERC-20 (/rh/check). One-sentence verdict + blocking/warnings/unknowns, casino|speculative|legit tier, holder count & concentration, liquidity, 1h volume & buy/sell flow, honeypot/tax or mint/freeze authority, RugCheck/GoPlus cross-checks. $0.01 USDC on Base or Solana via x402. Also: Hyperliquid perp market data for trading agents: funding extremes across all HL perps ($0.002), whale liquidation levels ($0.003), whale net positioning ($0.005), and a one-call LLM-ready market brief ($0.008). Refreshed ~every 3 min from HL public data; every response has generated_at/age_s; stale data is never charged.

## Output
