How this service works
Chinese crypto market brief as structured JSON for agents. Input symbol (+ optional context). Output bias/thesis/bullets/risks/actions. $0.03 USDC per call. Not financial advice.
Output
A JSON object containing: ok status, symbol, market bias (bias), short thesis (thesis), bullet points summarizing key market conditions (bullets), risk factors (risks), suggested actions (actions), a confidence score (0-1), an invalidation condition, a product identifier, and a disclaimer — all in Chinese by default.
Example use cases
Pre-trade BTC market check
“Before I make a move, give me a quick structured brief on BTC — what's the current bias, what's the thesis, and what should I watch out for? Focus on spot market conditions.”
ETH perp trading intelligence
“I'm looking at ETH perpetuals — can you pull a Chinese-language market brief for ETH with a perp focus, including risks and recommended actions?”
SOL narrative briefing with news context
“Here's a recent news blurb about Solana: 'SOL hits all-time high amid memecoin frenzy and institutional inflows.' Can you generate a structured crypto brief for SOL using this as context, with news as the focus?”
