01 · Reference object记录
Instrument or company
The source-defined security, index, currency, fund, or company identity associated with an observation.
- Source identifier and ticker
- Venue or market label
- Company relationship
Financial & market data
Market observations with their evidence still attached.
Collect public instrument, company, price, metric, filing, event, and revision records with source context and observation time preserved—from documented finance and trend APIs to a scoped recurring delivery.
Market record model
Separate the entity from every value observed about it.
A ticker, a company, a displayed quote, a filing, and a source revision answer different questions. Keeping them separate makes history and conflicts inspectable.
02 · Time-bound object记录
Quote or price observation
A value displayed by a named source with currency, context, source time where shown, and observed_at.
- Displayed value and unit
- Source-displayed time
- Observation state
03 · Public document飞行员先
Filing or disclosure
A public document and its amendment relationships, kept separate from facts extracted from it.
- Document type
- Published or filed time
- Revision reference
04 · Observed fact飞行员先
Metric
A source-labeled company, financial, economic, or interest measure with period and unit context.
- Metric label and value
- Period and units
- Source definition
05 · Change object飞行员先
Event
A source-published announcement or a change derived from successive observations under an agreed rule.
- Event type
- Effective or observed time
- Evidence links
06 · Evidence stateRetained
Source revision
A corrected, amended, or newly observed source state linked to the earlier record. Revisions do not overwrite the evidence trail.
Capability boundary
Documented where the product contract exists. Pilot-first where the source defines the work.
Coverage means a named source, page family, input, field set, timestamp policy, and permitted delivery—not a claim to complete market truth.

Record schema
Make source, value, time, and revision independently queryable.
The schema keeps what the source displayed separate from what the customer later derives, adjusts, joins, or decides.
Instrument and company
- source_instrument_id
- Identifier retained from the source.
- ticker
- Displayed symbol, without assuming global uniqueness.
- venue_label
- Market or venue context shown by the source.
Value and units
- displayed_value
- Source-presented value stored without interpretation.
- currency_or_unit
- Unit context associated with the value.
- observation_state
- Observed, absent, unavailable, failed, changed, or review.
Independent clocks
- source_time
- Timestamp displayed by the source, when present.
- observed_at
- When collection produced the observation.
- delivered_at
- When the record entered the delivery channel.
Provenance and revision
- source_url
- Public page associated with the record.
- revision_id
- Version key linked to prior evidence.
- schema_version
- Contract version used for the output.

}Identity and evidence
A ticker alone is not a canonical instrument.
Symbols can collide, change, or refer to different instruments by venue. Preserve the source identity and add cross-source identity only with inspectable rules.
- 01
Source key
Page ID + source URL
Retained as observed. - 02
Candidate cues
Ticker + venue + name
Compared under a versioned rule. - 03
Match state
Matched / ambiguous / review
Never silently forced. - 04
Canonical key
Customer or contracted ID
Added only when scoped.
Freshness semantics
Preserve the clocks; do not imply a live feed.
A collection schedule, source-displayed timestamp, and delivery time answer different questions. Observation timestamps remain attached to every record.
- Requestedrequested_at
The instrument and context entered collection.
- Source-displayedsource_time
The time shown by the page, when present.
- 观察到observed_at
The value was collected from the source.
- Delivered / reviseddelivered_at · revision_at
The record arrived or new source evidence appeared.
Quality and missingness
Quality means traceable evidence, not a promised market truth.
Structural checks can show whether the record matches the agreed contract. They cannot turn a public page into an authoritative or licensed price source.
Required evidence present
Value, source, identity context, and observed_at passed structural checks.
New source state linked
The previous record remains available beside the new observation.
Identity or value conflicts
The record waits for the agreed rule or customer review path.
No qualifying observation
Source absence or failure stays distinct from a valid zero value.
Structural checks
Required keys, types, timestamps, source URL, schema version, and state.
Field checks
Currency or unit presence, value format, identity cues, and revision linkage.
Customer acceptance
Source suitability, economic meaning, licensed-use requirements, calculations, and investment or operational decisions.
Operating model
Choose who runs the market-observation workflow.
The record contract stays explicit across four paths; ownership of collection, extraction, maintenance, and delivery changes.
Maximum control
Build on proxy infrastructure.
Your team selects sources and owns collection logic, extraction, timestamp policy, evidence retention, validation, and delivery.

Evaluation FAQ
Questions to settle before market observations enter production.
Use these answers to distinguish source observations from licensed feeds, interpretation, and financial decisions.
What financial and market data can WebScrapingAPI collect?
Documented Google Finance API and Google Trends API workflows can return source-specific public observations. Eligible public company and market pages can also be evaluated through Scraper API or Browser API. Filings, news, fundamentals, longer time series, and alternative-data feeds begin with a representative pilot.
Is this an official or licensed market data feed?
No. WebScrapingAPI is not a licensed exchange feed or official market data source. Records reflect values observed on named public webpages in a defined context and at a recorded time; regulated exchange distribution or licensed-feed replacement is not standard scope.
Does the data provide investment advice?
No. The delivered records are source observations, not investment advice, a recommendation, or a determination of value. Customers remain responsible for validation, analysis, permissions, controls, and every financial or operational decision made with the data.
How are instruments and companies identified?
The record can retain the source identifier, ticker, exchange or venue label, company name, and source URL. A cross-source canonical instrument or company identifier is added only when matching rules, ambiguity states, and review handling are part of the agreed contract.
How are timestamps represented?
Every observation preserves observed_at, and can retain requested_at, delivered_at, and any source-displayed time separately. A displayed market time is not silently substituted for collection time, and timezone interpretation is documented where the source provides enough context.
Can historical prices and revisions be delivered?
A scheduled or managed program can retain successive public observations and source revisions after collection begins. Historical backfill, interval completeness, corporate-action adjustment, and revision behavior are pilot-first because they depend on the source and requested record contract.
Can filings, fundamentals, and financial news be included?
Eligible public filings, disclosures, company metrics, and news pages can be evaluated in a pilot. The pilot confirms document types, jurisdictions, source permissions, fields, timestamps, amendment handling, and whether discovery metadata or extracted content is required.
How are missing, stale, or conflicting values handled?
The contract can distinguish a source-absent field, an unavailable page, an unchanged value, a late observation, a collection failure, a source revision, and a cross-source conflict. Those states remain explicit rather than becoming zero, null, or a fabricated consensus value.
Who maintains collection and quality controls?
Proxy customers own their collectors, parsers, validation, and maintenance. WebScrapingAPI maintains supported access products within their documented boundary. Scheduled feeds and Managed Web Data can include contracted extraction, schema maintenance, quality monitoring, revision handling, and delivery operations.
What data is outside the standard scope?
Non-public data, account-only terminals, credentialed portals, licensed exchange redistribution, order or portfolio data, and sources whose terms or controls prohibit the proposed use are not standard scope. A public observation never removes the customer's responsibility to assess lawful access, reuse, and retention.
