Parameters

Query parameters

yearintegeroptional

Return only the files of this year. Fundamentals and earnings calls use the fiscal year, stock prices use the calendar year. A year without files returns an empty list.

Example: 2026Min: 1900Max: 2100
periodstringoptional

Return only the file of this calendar month as two digits, 01 through 12.

Example: 08Values: 010203040506070809101112

Response

Each item is one file with its size, its SHA-256 digest, and a signed url. Items are sorted newest year first, then month order. Without filters the list holds every file, so the page URLs are always null. The example response is cut after two files. The response is not cached because every link expires one hour after the request.

Response fields

dataarray of objects

Array of file resources, newest year first. Without filters the array holds every available file, so the page URLs are always null.

+ Show child attributes
idstring

Stable identifier of the file, prefixed bulk_. It is derived from the storage path, so a rebuilt file keeps the same ID.

datasetstring

Dataset the file belongs to: fundamentals, earnings-calls, or stock-prices. The value is plural even for the singular /fundamental/bulk route.

yearnumber

Year of the data in the file. Fundamentals and earnings calls use the fiscal year. Stock prices use the calendar year.

periodstring

Slice of the year in the file. Fundamentals: annual, quarterly, or ttm. Earnings calls: q1 through q4. Stock prices: two-digit month 01 through 12.

formatstring

Always csv. The first row is a header row, and values obey RFC 4180.

compressionstring

Always gzip. Decompress the file before you read the CSV.

sizenumber

Size of the compressed .csv.gz file in bytes. The decompressed CSV is about three to four times larger.

sha256string

SHA-256 hex digest of the compressed file exactly as delivered. Compare it with the digest of your download before you decompress.

updated_atstring

ISO 8601 timestamp of the last rebuild of this file.

urlstring

Signed download link on bulk.roic.ai. Send a plain GET request without your API key and keep the verify token intact. Treat the link as a secret. The file host refuses links without a valid token.

expires_atstring

ISO 8601 timestamp after which url stops working, one hour after the request. Call the route again for fresh links if they expire before you start a download.

next_page_urlnullable

Relative URL of the next page, or null on the last page. Never contains your API key.

previous_page_urlnullable

Relative URL of the previous page, or null on the first page.

File contents

Each file is a gzip-compressed CSV with a header row. Rows are sorted by date, then by symbol. Prices are unadjusted, exactly as they traded on that day. To restate prices for splits or dividends, use the historical stock prices route with the adjustment parameter.

ColumnTypeMeaning
symbolstringExchange-qualified ticker, for example NASDAQ:AAPL.
datedateTrading day in YYYY-MM-DD format.
opennumberPrice of the first trade of the regular session.
highnumberHighest price traded during the session.
lownumberLowest price traded during the session.
closenumberPrice of the last trade of the regular session.
volumeintegerNumber of shares traded during the session.
currencystringISO 4217 code of the price currency, for example USD or EUR.

The first rows of the August 2026 file:

symbol,date,open,high,low,close,volume,currency
LSSI:121806,2026-08-01,14.35,14.35,14.35,14.35,82,EUR
LSSI:200417,2026-08-01,58.86,58.86,58.86,58.86,2,EUR
LSSI:394869,2026-08-01,5.715,5.715,5.715,5.715,5,EUR

Download, verify, and decompress

Run these commands to download one month, verify the digest, and decompress the file. Replace YOUR_API_KEY with your key.

# 1. Get the link and the digest of one file
RESP=$(curl -s -H "Authorization: Bearer YOUR_API_KEY" \
  "https://api.roic.ai/v3.0.0/stock-prices/bulk?year=2026&period=08")
URL=$(echo "$RESP" | jq -r '.data[0].url')
SHA=$(echo "$RESP" | jq -r '.data[0].sha256')
 
# 2. Download the file before the link expires
curl -o roic-stock-prices-2026-08.csv.gz "$URL"
 
# 3. Verify the digest
echo "$SHA  roic-stock-prices-2026-08.csv.gz" | shasum -a 256 -c
 
# 4. Decompress
gunzip roic-stock-prices-2026-08.csv.gz

The same steps in Python, with the file streamed to disk:

import gzip
import hashlib
import requests
 
API = "https://api.roic.ai/v3.0.0"
HEADERS = {"Authorization": "Bearer YOUR_API_KEY"}
 
listing = requests.get(
    f"{API}/stock-prices/bulk", params={"year": 2026, "period": "08"}, headers=HEADERS
).json()
meta = listing["data"][0]
 
digest = hashlib.sha256()
with requests.get(meta["url"], stream=True) as download, open("prices.csv.gz", "wb") as out:
    for chunk in download.iter_content(chunk_size=1 << 20):
        digest.update(chunk)
        out.write(chunk)
 
assert digest.hexdigest() == meta["sha256"], "digest mismatch, download again"
 
with gzip.open("prices.csv.gz", "rt", newline="") as csv_file:
    header = csv_file.readline().rstrip("\n").split(",")
    print(header)

Errors

StatusCodeCause
400invalid_parameterperiod is not a month from 01 to 12, or year is not a number.
401authentication_requiredThe API key is missing. Related codes: invalid_api_key and multiple_authentication_methods.
402bulk_download_restrictedThe plan does not include bulk downloads.
429rate_limit_exceededThe request limit is reached. Retry after Retry-After.

A year without files returns an empty data array. The file host bulk.roic.ai blocks a link without a valid verify token or after expires_at. Call the route again for fresh links.
