从 AI Agent 的角度比较市场情绪 API：新闻情绪、ticker 信号、来源质量、事件背景和市场监控工作流。
Market Sentiment APIs: What AI Agents Need
Market Sentiment APIs：AI Agent 真正需要什么
A market sentiment API for an AI agent must do more than return a score. The agent needs entity mapping, source quality, timestamp, topic tags, confidence, and enough market context to decide whether sentiment should trigger research, alerts, or no action.
面向 AI Agent 的 market sentiment API 不只是返回一个分数。Agent 需要实体映射、来源质量、时间戳、主题标签、置信度，以及足够的市场背景来判断情绪是否应该触发研究、预警或不执行动作。

Market Sentiment API Calibration
市场情绪 API 的校准方式
Market sentiment APIs need calibration because sentiment is not the same as news. A negative article about falling costs may be positive for margins, while bullish social chatter may have no institutional relevance. Agents should compare sentiment score, source type, asset class, time decay, volatility regime, and whether the signal historically correlates with price movement for the same sector.
市场情绪 API 需要校准，因为情绪不等于新闻。一篇关于成本下降的负面文章可能对利润率是利好，而社交媒体上的看多情绪也可能没有机构相关性。Agent 应比较情绪分数、来源类型、资产类别、时间衰减、波动率环境，以及该信号在同一行业中是否曾与价格变化相关。
How Market Sentiment APIs Differ from News APIs
市场情绪 API 与新闻 API 的区别
Market sentiment APIs convert text, social activity, options behavior, or survey-style signals into a directional measure. That makes them useful, but also noisy. Agents should treat sentiment as a hypothesis that needs confirmation from price movement, volume, fundamentals, or news context.
市场情绪 API 会把文本、社交活动、期权行为或调查类信号转成方向性指标。这很有用，但噪声也更大。Agent 应把情绪当作需要验证的假设，再用价格波动、成交量、基本面或新闻背景确认。
Sentiment Signals to Inspect
需要检查的情绪信号
| Signal origin | News, social, analyst commentary, options flow, or survey data behave differently. |
| Time decay | A one-hour social spike and a two-week analyst downgrade should not share the same weight. |
| Asset mapping | Sentiment may apply to a company, sector, coin, commodity, or macro theme. |
| Historical usefulness | Backtest whether the sentiment source has explained prior moves in the same market. |
Building a Sentiment-Aware Agent
构建情绪感知型 Agent
A sentiment-aware agent should first ask what the signal represents, then inspect whether the API exposes confidence, source mix, and timestamps. Only after that should it combine sentiment with price, news, and fundamentals. QVeris can route those follow-up calls so the model does not treat sentiment as a standalone truth.
情绪感知型 Agent 应先判断信号代表什么，再检查 API 是否暴露置信度、来源构成和时间戳。之后才应把情绪与价格、新闻和基本面结合。QVeris 可以路由这些后续调用，避免模型把情绪当成独立真相。
