What a free economic news API should help you build免费财经新闻 API 应该支持哪些产品需求

Developers need an API they can test, a clear free-plan boundary, an inspectable response, and enough source evidence to decide whether it fits a news feed, macro monitor, research Agent, or prototype. The first design decision is whether the product needs articles, scheduled events, official indicator values, or a linked combination of all three.

开发者需要的是可直接测试的接口、明确的免费边界、能够检查的响应结构，以及足以验证来源的证据，从而判断它是否适用于新闻流、宏观监控、研究 Agent 或产品原型。第一步不是先选供应商，而是确认产品需要新闻文章、计划事件、官方指标数值，还是三者相互关联的组合。

Economic news API coverage and filter options财经新闻 API 的覆盖范围与筛选功能

Useful coverage includes recent headlines, REST or JSON delivery, named sources, countries, languages, economic categories, entity or ticker tags, sentiment, and date filters. Every coverage claim is provider-specific: confirm it with real queries and current documentation rather than assuming an “economy” category includes official releases, calendars, and explanatory reporting.

实用的覆盖能力包括近期标题、REST 或 JSON 返回、明确来源、国家、语言、宏观主题、实体或股票代码标签、情感字段与日期筛选。所有覆盖描述都只适用于具体供应商，应通过真实查询与当前文档核对，不能因为接口提供“财经”分类，就默认它同时包含官方发布、经济日历和解释性报道。

Choose the right source for economic news and data为财经新闻与宏观数据选择正确来源

A robust macro product usually combines several source types instead of forcing one endpoint to do everything. Official APIs establish the numeric record, release feeds establish what the institution published, news aggregators add interpretation and cross-source coverage, and calendar services add consensus and scheduled-event structure.

可靠的宏观产品通常需要组合多类来源，而不是让一个接口承担所有任务。官方 API 用于确定数值记录，机构发布源用于确认原始公告，新闻聚合接口提供解释和跨媒体覆盖，经济日历服务则补充市场预期与计划事件结构。

Worked example: a CPI surprise needs units and vintages实例：计算 CPI 预期差必须先统一单位与数据版本

Suppose the calendar consensus is 0.3% month over month and the official release reports 0.4% month over month. The surprise is +0.1 percentage point, not “0.1% higher” unless the product explicitly uses a relative calculation. If another feed reports 3.2% year over year, subtracting 0.3 from 3.2 is meaningless because the transformations differ. Store the period, seasonal-adjustment flag, transformation, unit, consensus snapshot time, first released value, and later revision.

假设经济日历给出的市场预期为环比 0.3%，官方初值为环比 0.4%，预期差应表达为高出 0.1 个百分点；除非产品明确采用相对变化算法，否则不能写成“高 0.1%”。如果另一个接口返回同比 3.2%，也不能用 3.2 减去 0.3，因为两者的变换口径不同。应保存统计期、季调标记、变换方式、单位、预期值截取时间、首次公布值和后续修订值。

Now assume the previous month's value was initially 0.2% and later revised to 0.3%. A live alert should preserve the originally available prior when explaining the immediate reaction, while a current dashboard may show the revised history with an explicit revision marker. Overwriting the prior value erases what market participants actually knew at the release time and contaminates event-study backtests.

再假设上月数据最初公布为 0.2%，随后修订为 0.3%。解释即时市场反应的实时提醒，应保留发布当时可见的原始前值；当前看板可以展示修订后的历史，但必须明确标记修订。直接覆盖前值会抹掉市场参与者在发布时真正掌握的信息，并污染事件研究回测。
