What a free financial news API should support免费财经新闻 API 应支持哪些任务
This is the broad provider-selection page. It helps a product team compare financial-news universes across macroeconomics, companies, markets, regions, languages, publishers, history, enrichment, and content rights. It does not attempt to teach a full Python client or focus only on stock-ticker alerts; those narrower jobs have dedicated guides.
这是面向供应商选型的广义页面，帮助产品团队从宏观、公司、市场、地区、语言、媒体来源、历史深度、增强字段和内容权利等维度比较财经新闻数据。它不负责完整讲解 Python 客户端，也不只聚焦股票代码告警；这两类更窄的任务另有专门指南。
Test macro, policy, rates, currencies, commodities, credit, private-company, and public-market queries—not only one famous ticker.
同时测试宏观、政策、利率、外汇、商品、信用、非上市公司和公开市场查询，而不是只测一个热门股票代码。
Measure distinct publishers, geographic concentration, syndication, native languages, and ingestion delay over a fixed window.
在固定时间窗内测量不同媒体数量、地区集中度、转载情况、原生语言和收录延迟。
Separate permission to fetch metadata from permission to store text, display snippets, redistribute feeds, create embeddings, or train models.
区分抓取元数据与保存正文、展示摘要、再分发数据流、生成向量或训练模型的不同权利。
Compare free financial news APIs by editorial coverage and rights按内容覆盖与使用权比较免费财经新闻 API
Define the editorial universe first
Decide whether the product needs macroeconomics, central banks, commodities, currencies, rates, credit, private companies, public equities, or all business news. A provider with excellent US ticker coverage may still miss policy and cross-asset events.
Audit source diversity and language coverage
Count distinct publishers over a fixed week, inspect geographic concentration, and separate original reporting from syndication. Test requested language, detected article language, and translated summaries as different fields rather than one “multilingual” claim.
Model article identity and revisions
One market event can produce an original wire story, many syndicated copies, follow-up analysis, and a later correction. Prefer stable article IDs and canonical URLs, but also retain publisher, original source, published time, updated time, language, and related-story links. Define whether corrections replace, version, or flag an earlier record.
Confirm storage, display, and model-input rights
A free response does not automatically permit full-text storage, public display, redistribution, embeddings, or model training. Record whether the API returns licensed text, snippets, metadata, or links and what attribution must accompany each use.
Separate primary documents from reporting
Filings, issuer releases, exchange notices, central-bank statements, and statistical releases are primary evidence; publisher stories add interpretation. Preserve source type and the original document link so a research agent can cite the official number while still using journalism for context.
Keep relevance, novelty, sentiment, and impact distinct
An article can be strongly negative but only mention the requested company, highly relevant but repeat an old event, or novel without being market-moving. Require separate fields or calculate them independently with documented methods. Do not rank alerts using one opaque composite score.
Score against the intended workflow
A public feed needs display rights and clean media assets; a market alert needs low tail latency and correction events; a research agent needs history, source links, and replay; an archive needs retention and redistribution rights. The same provider can be excellent for one and unsuitable for another.
先定义财经新闻范围
明确产品需要宏观经济、央行、商品、外汇、利率、信用、非上市公司、上市公司，还是全部商业新闻。美国股票代码覆盖很强的供应商，仍可能缺少政策与跨资产事件。
审计来源多样性与语言覆盖
在固定一周内统计不同媒体数量，检查地区集中度，并区分原创报道和转载。请求语言、文章实际语言和翻译摘要应作为不同字段测试，不能只相信“支持多语言”的宣传。
建立文章身份与修订关系
同一市场事件可能对应通讯社原稿、多家转载、后续分析和之后发布的更正。应优先使用稳定文章 ID 与规范链接，同时保留发布媒体、原始来源、发布时间、更新时间、语言和关联报道。还要明确更正内容是覆盖旧记录、保留版本，还是触发复核标记。
确认存储、展示与模型输入权利
免费响应并不自动允许保存全文、公开展示、再分发、生成向量或用于模型训练。应记录接口返回的是授权正文、摘要、元数据还是链接，以及每种用途需要怎样署名。
区分一手文件与媒体报道
监管文件、公司新闻稿、交易所公告、央行声明和统计发布属于一手证据，媒体文章则增加解释。应保存来源类型与原始文件链接，让研究 Agent 可以引用官方数字，同时使用新闻报道补充背景。
分开处理相关性、新颖性、情绪与影响
一篇文章可能情绪强烈却只顺带提到目标公司，也可能高度相关但重复旧事件，或内容新颖却不影响市场。应要求这些字段独立返回，或使用有文档的方法分别计算，不要用一个不透明综合分值排序提醒。
按目标工作流评分
公开新闻流需要展示权和干净媒体素材；市场提醒需要较低尾部延迟与更正事件；研究 Agent 需要历史、来源链接和重放；归档还需要保存与再分发许可。同一供应商可能非常适合其中一类，却不适合另一类。

Free financial news API integration example免费财经新闻 API 接入示例
Keep the API key outside source code
Load the key from an environment variable. Set a finite timeout and avoid printing secrets in logs or notebooks.
Validate status, content type, and fields
Raise on HTTP errors, confirm JSON content, and reject items that lack the minimum fields your application requires.
Handle pagination and rate limits explicitly
Follow documented cursors, respect 429 and Retry-After, deduplicate by stable URL or provider ID, and preserve source timestamps.
Normalize an auditable article contract
Store provider and story IDs, canonical and primary-source URLs, publisher, source type, publication, update and ingestion times, language, entities, topics, event type, rights flags, and raw-response reference. Keep enrichment versions separate from immutable source metadata.
Evaluate with a fixed evidence set
Query known company, macro, policy, rates, commodity, and cross-asset events across two languages. Add duplicates, a correction, an ambiguous entity, an irrelevant mention, and an empty query. Measure recall, false matches, source diversity, duplication, field completeness, and freshness percentiles.
Monitor coverage and contract drift
Replay the evidence set, track disappearing publishers, language mix, correction latency, cursor gaps, null fields, schema changes, quota remaining, and rights updates. A healthy HTTP response can still conceal a materially degraded or newly restricted feed.
不要把 API Key 写进源码
从环境变量读取密钥，设置合理的超时时间，不要在日志或 Notebook 中输出密钥。
验证状态码、内容类型和字段
遇到 HTTP 错误时立即停止处理，确认返回内容为 JSON，并拒绝缺少应用必需字段的新闻记录。
明确处理分页和限流
遵循文档中的游标，处理 429 与 Retry-After，按固定 URL 或文章 ID 去重，并保留来源时间戳。
统一为可审计的文章契约
保存供应商与新闻簇 ID、规范与一手来源 URL、媒体、来源类型、发布/更新/收录时间、语言、实体、主题、事件类型、权利标志和原始响应引用。内容增强版本应与不可变来源元数据分开。
用固定证据集评估
使用两种语言查询已知公司、宏观、政策、利率、商品和跨资产事件，并加入重复稿、更正、歧义实体、无关提及和空查询。测量召回、错误匹配、来源多样性、重复率、字段完整性与新鲜度分位数。
监控覆盖与契约漂移
重放证据集，跟踪媒体消失、语言构成、更正延迟、游标缺口、空字段、Schema 变化、剩余额度与权利更新。即使 HTTP 响应正常，新闻流也可能已经明显降质或新增使用限制。

How QVeris helps with financial news API discoveryQVeris 如何帮助发现财经新闻 API 能力
QVeris helps agents discover callable capabilities and inspect their inputs and outputs. It does not guarantee that a provider is free, real-time, complete, or licensed for every use; those facts must be verified against current provider documentation.
QVeris 帮助 Agent 发现可调用能力并检查输入输出，但不保证服务商免费、实时、完整或适用于所有用途；这些事实必须以服务商当前文档为准。
- Open the QVeris tool details for financial or stock news capabilities.
- Inspect authentication, ticker parameters, result fields, and error behavior before connecting a workflow.
- Use the QVeris Python SDK documentation for the supported QVeris integration pattern.
- 在 QVeris 工具详情中搜索财经新闻或股票新闻能力。
- 接入工作流前检查鉴权、股票代码参数、返回字段和错误行为。
- 参考 QVeris Python SDK 文档了解受支持的接入方式。
FAQ
Yes. Some services expose a free tier or trial. Compare quota, delay, history, fields, supported markets, attribution, and commercial-use rules before choosing one.
Send an authenticated request with requests, pass a ticker or query, check the HTTP status, validate JSON fields, and handle pagination and rate limits.
Many finance-specific APIs expose ticker filters, but symbol formats and exchange mapping differ. Confirm parameters and test a known symbol in the current documentation.
Sometimes. Free history is often limited by date range, result count, or delayed access. Do not assume that a free current-news endpoint includes an archive.
Some return sentiment, entities, or relevance scores; others return raw articles only. Check field definitions, confidence, methodology, and supported languages.
RSS can suit permitted headline monitoring, but an API is usually easier for ticker filters, pagination, normalized JSON, history, and structured enrichment.
有些服务提供免费套餐或试用。选择前应比较配额、延迟、历史、字段、市场覆盖、署名和商用规则。
使用 requests 发送带鉴权的请求，传入股票代码或查询词，检查状态码，验证 JSON，并处理分页与限流。
很多金融专用接口支持股票代码，但代码格式和交易所映射不同，应查阅当前参数文档并用已知代码测试。
有时可以，但免费历史通常限制日期范围、结果数量或访问延迟，不能假设当前新闻接口自动包含完整档案。
部分接口返回情绪、实体或相关性，另一些只返回原始文章。应检查字段定义、置信度、方法和语言支持。
在许可允许的情况下，RSS 适合监控新闻标题；如需股票代码筛选、分页、标准化 JSON、历史数据和结构化增强字段，API 通常更合适。
