Financial data is ready for AI research when an agent can identify the entity, interpret the field, enforce the as-of date, trace the value to a source, apply the user's entitlement, and reproduce every transformation. An API or vector index alone does not satisfy that standard. The provider decision should begin with a data contract and acceptance tests, then choose the regulator, licensed originator, normalization service, or research layer needed for each field.
This field guide uses public documentation checked on August 30, 2026. It does not report a hands-on vendor benchmark. AllMind is an interested vendor in the research-system section. It provides integrated access to 6,800+ premium data sources from 100+ providers and partners under its licenses and partnerships rather than positioning itself as a standalone bulk-feed redistribution service.
An eight-part contract for AI-ready financial data
Require these properties for every field the agent may use:
| Contract property | Required metadata | Failure exposed |
|---|---|---|
| Identity | issuer, legal entity, security, listing, parent, effective dates | Ticker collision or wrong share class |
| Semantics | field definition, accounting basis, unit, scale, period type | Revenue mixed with net revenue or quarterly with annual |
| Event time | economic period and event timestamp | The value is assigned to the wrong period |
| Knowledge time | first availability and every revision timestamp | Look-ahead bias in historical research |
| Provenance | filing accession, vendor record, row, passage, or calculation inputs | A citation points to a document but not the fact |
| Transformation | normalization, FX, corporate action, formula, and software version | Standardized value cannot be reconciled to reported value |
| Entitlement | owner, user permission, permitted AI use, retention rule | A reachable field is used outside its license |
| Quality state | validation status, missing reason, restatement, confidence | Missing data becomes a fabricated value |
The contract should be queryable. A human-readable data dictionary is necessary, but an agent also needs stable field identifiers and machine-readable relationships between company, security, period, currency, and source.
A file is not point-in-time because it has a date column
Equity research uses at least three clocks:
- Period end: when the measured quarter or year ended.
- Publication time: when the company, regulator, or data vendor made the value available.
- Revision time: when a correction, restatement, mapping change, or normalization update arrived.
A backtest or historical thesis review must query the value available at the requested knowledge time. The latest restated database may be better for current analysis and wrong for reconstructing an earlier decision.
LSEG's point-in-time documentation explains that its historical datasets retain reported values and timestamp when they became available. FactSet's point-in-time consensus overview describes a daily local-market snapshot and excludes data entered after that cutoff. Those are examples of explicit temporal methodology. A buyer should obtain the corresponding rule for every purchased field, not assume one feed's method applies to the rest of the platform.
Provider roles are different by design
Regulators provide primary records
The SEC's EDGAR APIs expose submissions and extracted XBRL facts in JSON without an API key. The SEC says submissions update as filings are disseminated and XBRL endpoints cover standardized taxonomy facts associated with the filing entity. EDGAR supplies primary provenance and official filing identifiers.
It does not deliver a complete institutional consensus feed, cross-market corporate-actions history, clean global security master, or normalized industry KPIs. Company-specific XBRL extensions and context differences still need handling. Free access is valuable evidence, not a complete data architecture.
Licensed originators provide normalization and breadth
FactSet, LSEG, S&P Global Market Intelligence, Bloomberg, and other originators collect and normalize fundamentals, estimates, reference data, prices, ownership, transactions, and sector-specific fields. Each has different coverage, delivery, history, and methodology.
S&P's Capital IQ Pro page documents standardized company data, estimates, ownership, transactions, and AI-assisted document tools. Bloomberg's point-in-time company dataset documents corporate-action-adjusted actuals, estimates, guidance, pricing, and security-master data. The right choice depends on the fields and history in the research test, not the largest headline count.
Delivery products make licensed data usable by agents
An originator may deliver through a terminal, API, file, cloud share, or managed tool. Delivery changes the permitted workflow. A named-user terminal license should not be assumed to permit bulk indexing, persistent embeddings, model training, or redistribution.
When a research question spans prices, filings, and expert material, the cross-source platform map provides a separate rights schema for each content class.
LSEG's Microsoft partnership announcement describes a managed MCP server that can provide licensed LSEG data to agents built in Microsoft Copilot Studio and deployed in Microsoft 365 Copilot. FactSet's Portfolio Analytics MCP release describes governed performance, attribution, and risk outputs for conversational workflows. Both are examples of vendors packaging data and controls for agent use. Neither announcement grants a buyer rights beyond its agreement.
Research systems connect fields to the investment process
AllMind's data page names S&P Global/Capital IQ, FactSet, LSEG, MSCI, and exchange data such as CME across fundamentals, estimates, filings, market data, and research. The catalog includes FactSet Revere relationship data and Capital IQ index data. Those sources and a firm's own systems connect through the entity and relationship model on its ontology page, with citations and inherited permissions carried into the research workflow. These are AllMind's own claims and should be tested on the buyer's fields.
That unified research access does not automatically grant bulk redistribution rights outside the platform. AllMind is quote-based, and connecting a warehouse or internal system takes scoped onboarding. A firm exporting large histories for quantitative infrastructure should confirm the relevant originator and distribution rights.
Run one field through the whole chain
Use a field whose definition commonly changes, such as revenue for a company with segment reporting, acquisitions, or a fiscal calendar that differs from the calendar year. Select one filing and define the expected record before the vendor demo.
The acceptance packet should include:
- filing accession and filed timestamp;
- company and security identifiers with effective dates;
- reported value, tag or table location, unit, scale, and fiscal period;
- vendor-standardized value and field definition;
- any FX or corporate-action treatment;
- first availability time and revision history;
- point-in-time query for the day before and day after publication;
- the firm's internal forecast for the same definition and period;
- license clause or product schedule covering the proposed AI use.
Ask the platform to answer four questions:
- What did the company report, and where is it in the source?
- How does the standardized value reconcile with the reported value?
- What value would a user have seen at each requested historical timestamp?
- Why does the internal forecast differ, using only authorized evidence?
A pass requires field-level provenance, visible calculations, correct temporal results, and an entitlement record. A narrative answer without the record fails even if the number looks plausible.
Use deliberate failure cases
A polished normal case does not test the contract. Add these controlled failures:
Ticker reuse. Query an old ticker after a merger or rename. The result should resolve the entity by effective date.
Dual listing. Ask for a price without naming venue or currency. The system should ask for clarification or return the venue explicitly.
Restatement. Query the same period before and after a restatement. Both values and their availability dates should remain reconstructable.
Custom XBRL tag. Select a company-specific extension. The output should retain the original tag and disclose any mapping to a standardized field.
Missing consensus. Choose a thinly covered period. The system should return a missing state and contributor count, not infer a consensus from news.
Revoked permission. Remove access to one source and repeat the prompt. The restricted field should disappear or be marked unavailable without leaking cached text.
These tests are more diagnostic than asking a chatbot to summarize a well-covered mega-cap filing.
Licensing questions belong in the technical design
Ask counsel and the vendor to distinguish:
- display to a named user;
- API or cloud delivery;
- temporary prompt-time retrieval;
- persistent indexing or vectorization;
- fine-tuning or model training;
- storing prompts and generated outputs;
- derived data and calculation ownership;
- internal sharing and external publication;
- retention after the source license ends.
The system should enforce the contract at query and export time. A warning in procurement documents does not prevent an agent from storing restricted text.
Evaluate data quality with field-level denominators
Do not score a provider with one universal percentage. Report the result by field and use case:
| Test | Denominator | Example output |
|---|---|---|
| Entity resolution | all test securities and historical entity events | 48 of 50 resolved with correct effective dates |
| Source reconciliation | all standardized fields in the packet | 37 of 40 reconciled within defined tolerance |
| Point-in-time accuracy | all requested knowledge-time snapshots | 29 of 30 returned the correct vintage |
| Citation precision | all opened citations | 44 of 46 landed on supporting rows or passages |
| Permission accuracy | all allowed and denied requests | 20 of 20 enforced correctly |
| Missing-state behavior | all intentionally absent values | 8 of 8 returned explicit missing states |
The numbers above illustrate the reporting format only. They are not product results. Publish scores only after running the disclosed test and keep the failed records available for review.
What public documentation cannot answer
Product pages cannot establish field-level coverage for a firm's universe, package-specific rights, historical correction behavior, or real latency during a filing burst. They also cannot prove that identifiers survive joins across the firm's models and documents. Those questions require the acceptance packet, raw outputs, data dictionaries, and a written license.
An architecture may legitimately use EDGAR for primary filings, an originator for normalized and licensed data, and a research system for cross-source work. The test is whether lineage, time, semantics, and rights remain intact across the handoffs.

For an AllMind pilot, choose one field and run the full acceptance packet. Bring the originator's data dictionary and the relevant license language so the output can be checked for semantics and permitted use, not only numerical agreement.
