Tiingo

Use in your agent

Analyze Tiingo end-of-day prices in memory on the Starter plan. Checked against the provider's documentation on Oct 29, 2026.

Access

• A Starter account and API token are required. Put the token in TIINGO_API_KEY.
• Starter data may be processed only in volatile memory or a temporary non-persistent cache.

Request

curl -H 'Authorization: Token '$TIINGO_API_KEY 'https://api.tiingo.com/tiingo/daily/AAPL/prices?startDate=2026-10-01&endDate=2026-10-29'

Format

JSON array with date, OHLC, volume, adjusted OHLC and adjusted volume fields.

Load into pandas (in memory)

Needs Python 3 with requests and pandas. The provider's terms limit storage or leave it unclear, so this snippet does not write a file.

"""Tiingo Starter end-of-day prices -> pandas in memory. Do not persist Starter data."""
import os
import requests
import pandas as pd

headers = {"Authorization": f"Token {os.environ['TIINGO_API_KEY']}"}
params = {"startDate": "2026-10-01", "endDate": "2026-10-29"}
r = requests.get("https://api.tiingo.com/tiingo/daily/AAPL/prices",
                 headers=headers, params=params, timeout=30)
r.raise_for_status()
df = pd.DataFrame(r.json())
df["date"] = pd.to_datetime(df["date"], utc=True)
print(len(df), "rows", df["date"].min().date(), "to", df["date"].max().date())
del df  # Starter terms require deletion before this process, job or session ends

Needs a personal API key; not run.

Limits

• Starter: 50 requests per hour, 1,000 requests per day, 500 unique symbols per month and 1 GB per month.

Quirks

• The snippet intentionally writes no file.
• Delete the response and derived results before the process, job or session ends.
• Dates are ISO timestamps; parse them as UTC.

Terms and attribution

• Starter and trial users may not retain Tiingo data or derived products in persistent or durable storage.
• API data is for internal consumption; organizational use requires a commercial plan.
• Redistribution requires permission and additional fees.
