Securities

Parameters#

limitintegeroptional · query

Maximum records per page, from 1 to 500; default 100.Default: 100

cursorstringoptional · query

Opaque cursor, expires after one hour. Keep all query parameters unchanged. Changes to entitlements can invalidate it.

If-None-Matchstringoptional · header

ETag from a previous response. Authorization is rechecked before returning 304, and a 304 costs no credits.

symbolsstringoptional · query

Comma-separated MIC:TICKER symbols (crypto pairs are CRYPTO:BTC-USD, currency pairs FOREX:EUR-USD, indices INDEX:GSPC, bonds BOND and the ISIN, such as BOND:US00037BAF94) or bare tickers, which resolve to the exchange listing that ticker; neither part is case-sensitive, and two spellings of one listing count as a repeated value. A bare ticker that names no listing as written is also read in the common vendor spellings: with an exchange suffix (RY.TO, SHEL.L, VOD.LSE, BHP.AX), ^GSPC for INDEX:GSPC, and EURUSD=X or EURUSD for FOREX:EUR-USD. At most 100, further limited by the effective plan and key scope. A symbol names the listing recorded under it at symbol_at; at a date before any ticker is recorded for a listing, the earliest ticker recorded for it selects it as well (see symbol_at). Supply symbols or instrument_ids.

instrument_idsstringoptional · query

Comma-separated stable instrument IDs (the instrument_id of each row, and of the research endpoints) instead of symbols; each selects its listing at any date, including history from before its earliest recorded ticker and listings that no longer trade. Rows carry the symbol the listing had at symbol_at, or where it had none then, its symbol at as_of, else the last one it carried by as_of, else its first. At most 100. Cannot be combined with symbols.

symbol_atstringoptional · query

Resolve symbols as they were assigned at the end of this UTC date (YYYY-MM-DD); defaults to as_of. Only listings the security master holds resolve: it was built in September 2026 and records delistings from then on, so most issuers delisted earlier, such as TWTR or SIVB, resolve at no date. A ticker names the listing that carries it at symbol_at, and every row of a from/to range carries that symbol, rows from before the listing took the ticker included: a ticker reused after its earlier holder delisted returns the new holder's older rows, so set symbol_at inside the range to name the listing that traded under the ticker then. Tickers are recorded only where there is evidence for them (for many listings from 2003, though prices start earlier), and none is asserted earlier. As a lookup convenience, a date before a listing's earliest recorded ticker still finds the listing by that ticker when no record contradicts it (no listing is recorded under the ticker by that date, and the listing has no earlier ticker): its rows carry the symbol as a label and meta.unrecorded_symbols lists it. A date before the listing's first row returns 200 with no-data, as a to before it does. A ticker another listing held, or one the listing was renamed from or to, returns 404 naming the date and the listing; instrument_ids select a listing at any date.

as_ofstringoptional · query

Knowledge cutoff as a UTC date (YYYY-MM-DD): the response reflects what was known by the end of that day. Defaults to now; cannot be in the future. A date from before the dataset's knowledge history returns 422 point-in-time-unavailable naming the earliest one, which GET /v1/datasets lists as earliest_as_of.

formatstringoptional · query

Response format. csv returns the data rows with a header row, for spreadsheet functions such as IMPORTDATA; nested fields become dotted columns and lists one JSON array cell, the next page cursor is returned in X-Next-Cursor and meta.errors in X-Meta-Errors. A result without rows is the header row alone, listing the documented fields of a row. Default json, or csv when format is omitted and the Accept header ranks text/csv above JSON; a format the Accept header does not admit returns 406 not-acceptable.

jsoncsv

Response fields#

Returns data as an array of records. All example values are illustrative.

security_idstring

Deprecated: the same stable public ID as instrument_id, which replaces it.Being superseded by instrument_id, which carries the same value. Read instrument_id where present; security_id remains for compatibility.

instrument_idstring

Stable public instrument ID, independent of ticker; the instrument_id of the research endpoints.

Response metadata#

Responses include meta.timezone. Dataset responses include next_cursor; health and exports have their own metadata. Request tracing uses the X-Request-ID header.

When something goes wrong#

An empty data: [] is a successful query with no matching records. Invalid symbols, permissions and malformed parameters produce an RFC 9457 problem with an actionable detail.

Plans#

Requires reference.read. Access, recency and history depth come from the plan definitions the API enforces.

Free requests are limited to AAPL, NVDA, JNJ, PEP, MSFT, SPY, QQQ.

History is how far back a plan may request. How far records actually go for a symbol is history_from in dataset coverage. Nothing is real-time. Compare plans
