Why does the API return a 404 for my ticker?

A 404 on a per-ticker endpoint means there is nothing to return, and the error code in the response says why. Each code has a different next step.

error	What it means	What to do
entity_not_found	We track no stock by that symbol	Check the suggestions in the response, or search the company name, then retry with the real symbol
no_coverage	We track the symbol but have no data of that kind for it	Stop retrying this symbol on this endpoint. A different spelling will not help
ticker_is_etf	The symbol is a fund, so the question does not apply	Call one of the fund endpoints listed in seeInstead
ticker_is_index	The symbol is a market index	Call one of the fund endpoints listed in seeInstead

Common causes

• The symbol is from a non-US exchange. Every ticker endpoint works on US-listed securities. For a foreign company, use its US-listed symbol, the ADR, not a home-market symbol such as SAP.DE.
• The path is in the wrong order. Check the endpoint against the API reference. A path with the ticker in the wrong place also returns a 404.
• It is a fund on a stock endpoint. Funds have their own endpoints.

An empty result is different from a 404. A known company with no readings in the requested window returns an empty 200 on the metrics endpoint.
