How this service works
Signed data for AI agents, paid per call over x402. Hyperliquid crowd state, smart money and liquidations with what historically happened next, plus independent checks of x402 services and MCP servers.
Output
A JSON object containing the total number of markets (e.g. 160), and an array of exchange-level breakdowns each with the exchange name, number of markets listed, and open interest in USD. Data is cryptographically signed by Annalist for agent-verifiable provenance.
Example use cases
Monitor crypto derivatives open interest
“What's the total open interest across all Hyperliquid perpetual markets right now, and how is it split between exchanges?”
DeFi dashboard market count refresh
“Refresh the Hyperliquid market stats for my dashboard — I need the current number of active markets and each exchange's open interest in USD.”
Pre-trade derivatives market sizing
“Before I place a large perp trade, can you check the overall Hyperliquid market open interest and see which exchanges are carrying the most exposure?”
Technical details
Endpoint
GEThttps://api.annalist.dev/v1/hip3/market?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need verified, signed aggregate market data for Hyperliquid perpetuals — especially when your agent pipeline requires cryptographically attested data or when you need open interest aggregated by exchange. Prefer over generic market data APIs when operating in an x402 micropayment context or when data provenance/signing is required for downstream trust.
Side effects
- Payment not included or insufficient — returns HTTP 402 requiring x402 payment
- Invalid or unrecognized 'properties' filter — may return empty or default market set
- Hyperliquid upstream data unavailable — service may return 503 or stale data
- Malformed request parameters — returns 400 bad request
