Tiingo Market Data

Decades of end-of-day price history, intraday IEX quotes, curated fundamentals and financial statements, corporate actions, news, crypto and FX — from Tiingo.

Tiingo publishes no OpenAPI document, so every endpoint here was verified against the live API (2026-08-17). The check was a discriminator, not an assumption: a real path answers 403 {"detail":"Invalid token."} with a bogus key, a made-up path answers 404. All ten returned 403; three nonsense paths returned 404.

Get a key

1. Sign up at https://www.tiingo.com/account/api/token.
2. Credentials → New → API Key, name it (e.g. Tiingo), paste the token.
3. Name it on the task: "credentialName": "Tiingo".

Sent as Authorization: Token … — a header, so the key stays out of URLs and logs.

Operations

Tickers are lower-cased automatically — aapl, spy, audusd.

Examples

Ten years of daily closes:

{"name":"history","tool":"tiingo","credentialName":"Tiingo",
 "properties":{"operation":"prices","ticker":"aapl","startDate":"2016-01-01","resampleFreq":"daily"}}

Dividend history, and news for a ticker:

{"properties":{"operation":"distributions","ticker":"ko"}}
{"properties":{"operation":"news","tickers":"aapl,msft","limit":"10"}}

Notes

• The free tier is generous on history but limited on breadth: 50 unique symbols/hour, 1,000 requests/day. 429 says which limit you hit.
• Fundamentals are curated rather than raw XBRL — cleaner than filings-derived data, narrower coverage.
• For US intraday and ETF holdings use finnhub; for non-US exchanges use eodhd.
• Verified: validation and auth wiring tested live (bogus key → 403 Invalid token.). No 200-level response recorded — that needs a real token.

Publishes

The keys a later task may reference as {{taskName.key}}. Referencing anything not listed here resolves to nothing at run time.
