Financial news API free decision board comparing coverage, freshness, access limits, usage rights, ticker testing, and QVeris connection

TL;DR快速结论

Choose by workload

A useful free tier must fit the required markets, delay, request volume, content rights, and integration workflow—not merely appear on a provider list.

What “free” means

It may mean a permanent quota, trial, delayed feed, sample dataset, or headlines-only access. Verify the current plan.

Minimum test

Request one ticker and time window, then validate source, publication time, URL, pagination, and rate-limit behavior.

QVeris role

QVeris helps agents discover and call relevant finance capabilities; provider terms and output still require verification.

按任务选择

真正可用的免费方案必须同时满足市场覆盖、时效、请求量、内容许可和接入流程,而不只是出现在供应商名单里。

“免费”的边界

免费可能指长期额度、限时试用、延迟新闻、样例数据或只返回标题,必须核对当前套餐。

最低测试

先请求一个股票代码和时间窗口,再验证来源、发布时间、URL、分页与限流行为。

QVeris 的作用

QVeris 帮助 Agent 发现和调用金融能力,但服务商条款和返回结果仍需逐项核验。

What a financial news API free plan must disclose免费财经新闻 API 必须说明哪些边界

The word “free” does not describe whether news is live, delayed, complete, redistributable, or suitable for production. Treat the pricing page, API documentation, and license as part of the data contract.

“免费”并不代表实时、完整、可再分发或适合生产。应把价格页、API 文档和许可条款视为数据契约的一部分。

Classify the access model before comparing quotas. A no-key public endpoint, recurring account-based free tier, time-limited trial, sandbox, sample dataset, and promotional credit are different products. Record signup and card requirements, renewal period, endpoint exclusions, regional restrictions, and what happens at the limit: HTTP 429, delayed data, paid overage, or suspension. Only a recurring allowance with documented terms should be modeled as ongoing free access; trials and credits are evaluation paths.

比较额度前,先判断免费方式属于哪一类。无需 Key 的公开端点、注册后周期性重置的免费层、限时试用、沙箱、样例数据集和赠送积分并不是同一种产品。应记录注册与绑卡要求、重置周期、不可用端点、地区限制,以及达到上限后是返回 429、切换延迟数据、产生付费超额,还是暂停账户。只有条款明确且周期性续期的额度才适合按长期免费接入测算;试用和积分只能视为评估路径。

Financial news API coverage

Check supported markets, languages, publishers, asset classes, and whether results cover company news, macroeconomics, funds, forex, or crypto.

Real-time financial news API latency

Compare the original publication timestamp with the API ingestion time. A free endpoint may be delayed, cached, sampled, or updated on a schedule.

Free API key, quotas, and history

Record daily and monthly requests, burst limits, pagination cost, date-range limits, retention, and whether a payment card is required.

Full text and redistribution rights

A response may include only a headline, teaser, and source link. Confirm attribution, storage, display, commercial-use, and full-text rights before shipping.

Article identity and revision history

Prefer stable article and story-cluster IDs, canonical URLs, original publisher, publication and update timestamps, and correction or retraction status. Deduplicate syndication without discarding the first source or later material updates.

Entity and event semantics

Confirm whether tickers are exchange-aware, whether company relevance differs from a simple mention, and whether events such as earnings, filings, guidance, M&A, rates, and macro releases use documented labels. Keep sentiment separate from relevance and event importance.

财经新闻接口覆盖范围

检查市场、语言、来源和资产类别,并区分公司新闻、宏观经济、基金、外汇与加密货币报道。

实时财经资讯 API 的延迟

对比原始发布时间与接口收录时间。免费接口可能延迟、缓存、抽样或按固定周期更新。

免费 Key、调用额度与历史范围

记录日/月请求量、突发限流、分页成本、日期范围、保存周期,以及是否必须绑定支付卡。

全文与再分发权限

接口可能只返回标题、摘要和来源链接。上线前必须确认署名、存储、展示、商用与全文权限。

文章身份与修订历史

优先选择能返回稳定文章 ID、新闻簇 ID、规范 URL、原始媒体、发布与更新时间以及更正或撤稿状态的接口。去除重复转载时,不能丢失首发来源或后续实质更新。

实体与事件语义

确认股票代码是否带交易所信息、公司相关性是否区别于普通文字提及,以及财报、监管文件、业绩指引、并购、利率和宏观数据是否采用有文档的事件标签。情绪、相关性与事件重要性应分别保存。

Treat one event, many URLs, and later updates as a story cluster把同一事件的多个链接与后续更新组织成新闻簇

Suppose a company publishes guidance at 08:00, a wire service reports it at 08:02, two portals syndicate the wire at 08:04, and the original publisher adds the CFO's explanation at 08:18. Five URLs do not necessarily represent five independent events. Cluster candidates by canonical URL, publisher lineage, normalized headline, named entities, event type, and close publication time—but retain every source record and its rights. The 08:18 article is a material update, not a duplicate to discard.

假设某公司在 08:00 发布业绩指引,通讯社在 08:02 报道,两家门户在 08:04 转载同一稿件,原始媒体又在 08:18 补充了 CFO 的解释。五个 URL 并不一定代表五个独立事件。可以依据规范 URL、媒体来源关系、标准化标题、涉及实体、事件类型和接近的发布时间生成候选新闻簇,但每条来源记录及其许可仍需保留。08:18 的新增内容属于实质更新,不能作为普通重复稿删除。

Timestamp时间字段Meaning含义Use in evaluation评估用途
published_atWhen the publisher first made the item public媒体首次公开发布该内容的时间Start of publisher-to-API latency计算媒体到接口延迟的起点
ingested_atWhen the API captured the item接口收录该内容的时间ingested_at − published_at measures delivery delayingested_at − published_at 用于衡量传递延迟
updated_atWhen the publisher or feed materially changed it媒体或数据源对内容作出实质修改的时间Detect corrections, added facts, and retractions识别更正、事实补充和撤稿
retrieved_atWhen your application fetched the record应用获取该记录的时间Diagnose polling and cache delay; it is not publication time诊断轮询和缓存延迟,不能当作发布时间

Measure initial delivery and update delivery separately. An API may surface the first headline quickly but miss a correction for hours. Preserve the provider's timezone or normalized UTC value, the original timestamp string, and a flag for estimated or missing times. Never replace an unknown publication time with retrieval time, because doing so makes a late historical article appear current.

首次报道延迟与后续更新延迟应分别测量:接口可能很快返回首条标题,却在数小时后仍未传递更正。应保存供应商时区或标准化 UTC 值、原始时间字符串,以及“时间为估算值或缺失”的标记。不能用获取时间代替未知的发布时间,否则一篇较早的历史报道会被错误显示为最新消息。

Test a free stock market news API before integration接入前测试免费股票新闻 API

Start with financial news by ticker

Query one documented symbol such as AAPL and a short date window. Confirm exchange mapping, duplicate stories, stable IDs, source URLs, and timezone handling.

Validate the financial news JSON API contract

Require a stable article ID, headline, source, URL, publication timestamp, language, and pagination marker. Treat sentiment and full text as optional unless documented.

Exercise rate limits and pagination

Follow documented cursors, handle 429 and Retry-After, set finite timeouts, retry only safe requests, and record gaps instead of interpreting them as no news.

Re-check production and commercial rights

Before launch, confirm whether the free plan permits production traffic, persistent storage, public display, model training, summarization, and redistribution.

Build a dated evaluation corpus

Use known company events, macro releases, multilingual stories, ambiguous tickers, duplicate wire copies, corrected articles, and an intentionally empty query. Measure relevant-event recall, wrong-entity rate, duplicate rate, missing fields, correction delivery, and median plus 95th-percentile ingestion delay.

Run the projected workload

Calculate requests from symbols, topics, polling intervals, active hours, pagination, and retries. Exercise the burst limit and a full quota cycle, then verify that caching and storage comply with the license. Keep capacity headroom for backfills and incident recovery.

先按股票代码查询财经新闻

使用 AAPL 等文档明确支持的代码和较短日期范围,检查交易所映射、重复报道、固定 ID、来源 URL 与时区。

验证财经新闻 JSON 字段

至少要求稳定文章 ID、标题、来源、URL、发布时间、语言与分页标记;情感和全文仅在文档承诺时视为必需。

测试限流与分页

遵循游标,处理 429 与 Retry-After,设置有限超时,只重试安全请求,并记录数据缺口。

再次核对生产与商用权限

上线前确认免费套餐是否允许生产流量、长期存储、公开展示、模型训练、摘要与再分发。

建立带日期的评估样本

样本应覆盖已知公司事件、宏观数据发布、多语言报道、歧义股票代码、重复通讯社稿件、被更正文章和一个预期为空的查询。测量相关事件召回、实体误关联率、重复率、字段缺失、更正传递,以及收录延迟的中位数和第 95 百分位。

按预计负载完整运行

根据标的、主题、轮询间隔、活跃时长、分页和重试计算请求量,实际触发突发限速并跑完一个额度周期,再确认缓存与存储符合许可。还要为历史回补和故障恢复保留容量余量。

Build an evidence packet before an AI agent summarizes the story让 AI Agent 生成摘要前先建立证据包

A production record should carry the stable article and cluster IDs, original publisher, canonical URL, headline, permitted excerpt, publication and update times, retrieved time, language, linked entity IDs, event label, relevance evidence, correction status, and content-rights flags. Store the provider response separately from extracted claims so a later correction can be traced to the exact version the agent saw.

生产记录应包含稳定文章 ID 与新闻簇 ID、原始媒体、规范 URL、标题、许可范围内的摘录、发布与更新时间、获取时间、语言、关联实体 ID、事件标签、相关性依据、更正状态和内容权限标记。供应商原始响应应与抽取后的事实主张分开保存,这样后续出现更正时,才能追溯 Agent 当时看到的具体版本。

📌 Reported fact📌 已报道事实

A value, date, action, or quotation explicitly supported by the linked source. Keep the source and passage location.

由链接来源明确支持的数值、日期、行动或引述,同时保留来源及其所在位置。

🗣️ Source interpretation🗣️ 来源观点

An analyst, executive, publisher, or other named source's judgment. Attribute it rather than presenting it as settled fact.

分析师、高管、媒体或其他明确主体的判断,应标注观点归属,不能写成已确定事实。

🧠 Model inference🧠 模型推断

A conclusion formed by combining evidence. Label the inference, cite the supporting records, and avoid inventing certainty when evidence conflicts.

模型综合证据后得出的结论,应明确标为推断、引用支撑记录,并在证据冲突时保留不确定性。

Release gate: reject or hold the answer when the entity match is ambiguous, the source URL is missing, a material correction has not propagated, licensing blocks the intended output, or the retrieved set has an unexplained time gap. Sentiment is a secondary annotation; it must never substitute for source evidence.

发布门槛:实体匹配存在歧义、缺少来源 URL、重要更正尚未同步、许可不允许预期输出,或返回结果存在无法解释的时间缺口时,应拒绝生成或暂缓发布。情绪只能作为辅助标记,不能替代来源证据。

FAQ常见问题

Is there a free API for financial news?

Yes. Current search results include providers advertising a free tier or free access. The quota, delay, fields, history, and usage rights differ, so verify the current documentation.

Can a free financial news API provide real-time data?

Sometimes, but “free” does not guarantee real time. Measure the gap between the source publication time and API ingestion time, and check whether the plan is delayed or cached.

Can I get financial news by ticker through an API?

Many finance-focused endpoints support ticker or entity filters. Test symbol mapping, exchange identifiers, duplicates, and whether the ticker match refers to the main subject or a passing mention.

Do free financial news APIs include full article text?

Not always. Some return headlines, teasers, metadata, and a source link. Full text, history, redistribution, and commercial display may require different rights or a paid plan.

Do I need an API key for a free financial news API?

Often yes, although some endpoints are keyless. Keep keys out of client code, inspect quota headers, and never assume keyless access permits unrestricted production use.

What should I validate before using news in an AI agent?

Validate the source, URL, timestamps, entity match, pagination, missing periods, and license. Preserve citations and avoid presenting sentiment or summaries as investment advice.

有免费的财经新闻 API 吗?

有。当前搜索结果中存在提供免费套餐或免费访问的服务,但额度、延迟、字段、历史范围和使用许可不同,应核对最新文档。

免费财经新闻接口能提供实时数据吗?

有时可以,但“免费”不等于实时。应测量来源发布时间与接口收录时间的差值,并确认套餐是否延迟或缓存。

可以按股票代码获取新闻吗?

许多金融新闻接口支持股票代码或实体筛选。需要测试交易所映射、重复报道,以及代码命中的是报道主体还是顺带提及。

免费接口包含新闻全文吗?

不一定。部分接口只返回标题、短摘要、元数据与来源链接;全文、历史、再分发和商用展示可能需要额外授权。

免费财经新闻 API 需要 Key 吗?

通常需要,但也有免 Key 端点。不要把密钥放在客户端代码中,并检查额度响应头;免 Key 不代表可以无限用于生产。

给 AI Agent 使用前应验证什么?

验证来源、URL、时间戳、实体匹配、分页、缺失时段与许可,保留引用,不把情感或摘要表述为投资建议。
