Mutual Fund & ETF Profile API
Retrieve master metadata and identifiers for mutual funds and ETFs by ticker, CUSIP, or SEC Series ID. The response maps the full identifier chain — CIK, Series ID, Contract ID, Series LEI, and class-level LEI — alongside the three-level name hierarchy that distinguishes the registrant trust from the fund series and individual share class. Query any fund or ETF in the Business Quant universe with a single identifier and receive the complete profile in return. The API is free to use.
Covers four fund types:

Related endpoints: Use the Stock Ticker List API to enumerate all available fund tickers and retrieve their Series IDs before calling this endpoint. For dividend history and yield, pass the seriesid returned here to the Dividends API. For SEC filings associated with the fund, pass the cik to the SEC Filings API.
Mutual Fund & ETF Profile API Capabilities
One call resolves any fund identifier to a complete profile — from the trust-level registrant down to the individual share class, with every SEC and market identifier mapped in a single response.
Three Identifier Modes
Query by ticker symbol, CUSIP, or SEC Series ID — whichever identifier your workflow already has. The API resolves all three to the same canonical fund profile.
Complete Identifier Map
Returns CIK, Series ID, Contract ID, Series LEI, and class-level LEI in one response — the full set of identifiers needed to cross-reference SEC filings, regulatory databases, and market data systems.
Three-Level Name Hierarchy
Resolves the full naming structure — registrant trust, fund series, and individual share class — so you can display the right name at any level of granularity without additional lookups.
Filing & Price Timeline
Returns the last SEC filing date, the last reporting period and the first available NAV price date — giving you the data coverage window for any fund before making downstream API calls.
Adviser Address & EDGAR Link
Returns the investment adviser's registered address and a direct link to the fund's SEC EDGAR filing page — both useful for compliance workflows and fund research pipelines.
Funds and ETFs Only
Only registered funds and ETFs resolve here — an operating company's ticker returns 404 rather than a record of empty fields. For equities use the Stock Profile API. Where a ticker was once a fund's and now belongs to a company, the fund is what you get.
1. Request Parameters
Provide api_key and at least one identifier — ticker, cusip, or seriesid. Supplying more than one is supported and narrows the lookup: the identifiers are combined with AND, so a set that does not describe a single record returns 404 rather than a list of near-misses.

2. Response Field Reference
Fields are grouped by category below. When querying by ticker or cusip the response is a flat JSON object. When querying by seriesid — which may match multiple share classes — the response is a JSON array of objects with the same schema.
Identifiers
| Field | Description |
|---|---|
| cik | SEC Central Index Key for the registrant entity. Use this to query SEC Filings associated with the fund trust. |
| ticker | Fund share class ticker symbol as listed on an exchange or used in fund data systems. May differ from the fund series name. |
| seriesid | SEC Series ID identifying the fund series within the registrant trust (e.g. S000009189). Use this to query the Dividends API in fund mode. |
| contractid | SEC Contract ID identifying the specific share class within the fund series (e.g. C000024974). Corresponds to a single ticker. |
| series_lei | Legal Entity Identifier assigned to the fund series. Used in regulatory reporting and cross-border fund data reconciliation. |
| lei | Legal Entity Identifier at the share class level. Distinct from series_lei — use this for class-specific regulatory lookups. |
Names — Three-Level Hierarchy
Fund naming in SEC filings follows a three-level structure. The registrant is the umbrella trust that files with the SEC. Within it sit one or more fund series, and within each series are one or more share classes. Each level has its own name field.
| Field | Description |
|---|---|
| name | Full legal name of the registrant trust as filed with the SEC. Typically uppercase (e.g. COLUMBIA ACORN TRUST). Use name_short for display. |
| name_short | Condensed display name of the registrant trust — title-cased and trimmed for use in UI components. |
| registrant_name | Full registered name of the legal entity filing with the SEC. Equivalent to name in most cases. |
| fund_name | Name of the specific fund series within the registrant trust (e.g. Columbia Thermostat Fund). This is the name investors typically recognize. |
| class_name | Full name of the individual share class including the class designation (e.g. Columbia Thermostat Fund Class A). Use this when displaying a specific ticker's identity. |
Classification & Metadata
| Field | Description |
|---|---|
| security_type | What kind of fund this is: Mutual Fund, ETF, Closed-End or UIT. These are the same four values the Fund Screener API filters on as vehicle, so the two endpoints agree on what a fund is. Nothing outside this list is ever returned — it is what keeps operating companies out of a /funds route. |
| entity_type | SEC entity classification for the registrant — typically investment for registered investment companies. |
Filing & Price Timeline
| Field | Description |
|---|---|
| lastfilingdate | Date of the most recent SEC filing by this registrant. Format: YYYY-MM-DD. |
| lastreportperiod | End date of the most recently reported period (e.g. the period covered by the last N-CSR or N-CEN filing). Format: YYYY-MM-DD. |
| firstpricedate | Date of the earliest available NAV price in the Business Quant database. null if price history has not been loaded for this fund. |
Contact & Links
| Field | Description |
|---|---|
| address_adviser | Registered address of the investment adviser in Street, City, State, Country, ZIP format. |
| url_edgar | Direct link to the fund's filing history on SEC EDGAR. Opens the registrant's complete filing index. |
3. Identifier Variations
All three identifier modes return the same response schema. Use whichever identifier your pipeline already has — no pre-resolution step required. Note that querying by seriesid returns an array when the series contains multiple share classes.
https://data.businessquant.com/funds/profile?ticker=CTFAX&api_key=YOUR_API_KEY
https://data.businessquant.com/funds/profile?cusip=19765N607&api_key=YOUR_API_KEY
https://data.businessquant.com/funds/profile?seriesid=S000009189&api_key=YOUR_API_KEY
Series ID returns an array. Many fund series have multiple share classes (Class A, Class C, Institutional, etc.) — each with its own ticker, CUSIP, Contract ID, and LEI. When you query by seriesid, the response is a JSON array with one object per class. Querying by ticker or cusip always returns a single flat object.

Frequently Asked Questions
What is the difference between seriesid and contractid?
A fund series (Series ID) is the named fund product — for example, the Columbia Thermostat Fund. Within that series, each share class — Class A, Class C, Institutional — is identified by a Contract ID and has its own ticker and CUSIP. If you want data for one specific share class, use its ticker or CUSIP. If you want all share classes in a series at once, query by Series ID.
How do I find the Series ID for a fund I already have a ticker for?
Query this endpoint with the ticker — the seriesid is returned in every response. Alternatively, the Stock Ticker List API returns seriesid for all funds in one call, making it easy to build a local ticker-to-series map.
What does firstpricedate being null mean?
It means NAV price history for that specific share class has not yet been loaded into the Business Quant database. The fund itself may still be active — check lastfilingdate and lastreportperiod to confirm. Check this field before calling price or dividend history endpoints to avoid unnecessary requests. There is no lastpricedate here: a fund's latest quote belongs to the price endpoints, which is where it is kept current, and a date copied into a registry record would go stale the day after it was written.
Which identifier should I use if I have all three available?
Prefer seriesid when you want every share class of a fund in one call. Prefer ticker when you want one specific share class. CUSIP is the most precise identifier — one CUSIP maps to exactly one share class — but it is not always available in consumer-facing datasets. Sending several at once is a constraint, not a shortcut: they are combined with AND, so ?ticker=VOO&cusip=<a different fund's> returns 404. Send one unless you are deliberately asserting that they describe the same record.
How is this different from the Fund Overview API?
They answer two different questions and share only five fields — cik, ticker, seriesid, fund_name and class_name. This endpoint is the registry record: the identifier chain and the SEC filing provenance behind it, for reconciling a fund against EDGAR. The Fund Overview API is the fund itself — expense ratios, assets under management, investment objective, principal strategy and every share class the fund offers. Build a fund page from Overview; resolve an identifier with this.
Why does a ticker I know exists return 404?
Two reasons. Either the ticker belongs to an operating company rather than a fund — this endpoint answers for funds and ETFs only, and an equity symbol is a 404 here rather than a row of empty fields; use the Stock Profile API for those. Or the fund is not in this registry table: a small number of share classes are reachable through the Fund Overview API and its portfolio endpoints without having a registry record here. Absence is always a 404, never a partial record.
Is the Funds Profile API free to use?
Yes, the API is free to use. Sign up for an API key and start querying fund profiles immediately — no credit card required.
