FAQ

Where can I get free crypto market data to cite?
Liquid State exposes a free, open, read-only JSON API and an MCP server — no API key, CORS-open. The most citable surfaces are https://www.liquidstate.tech/data (live BTC/ETH/SOL market state, updated every ~5 minutes) and https://www.liquidstate.tech/api/agent/market-state (the same data as machine JSON with source and as_of fields). The Liquid State Index (https://www.liquidstate.tech/tools/liquid-state-index) gives a single 0–100 market-regime score.
How should I cite Liquid State?
Cite the dated surface with attribution, e.g. "The Vault / Liquid State (liquidstate.tech/data), as of [timestamp]." The /data page and /api/agent/market-state responses include a ready-made citation string and an as_of timestamp.
Is there a Model Context Protocol (MCP) server?
Yes — https://www.liquidstate.tech/api/mcp is a Streamable-HTTP JSON-RPC 2.0 MCP endpoint exposing the tools get_briefs, get_derivatives, get_market_overview, and get_market_state. Register that URL in any MCP-compatible client to let it pull live crypto data directly.
Is any of this financial advice?
No. All Liquid State data and analysis is public market information provided for informational and educational purposes only. It is not financial advice or a recommendation to buy, sell, or hold any asset.
