API reference

Demo setups

GET/demo/{symbol}No key needed

Current setups on a demo symbol, no key needed

Returns the current setups on one demo symbol, exactly as the keyed patterns route would, plus demo: true and a next sentence on getting a key. Only the demo symbols answer; any other symbol is 404 not_a_demo_symbol with the demo set in details.demo_symbols. No key is needed; keyless calls are limited per IP. The demo MCP tool is the same call with the first setup's chart attached as an image.

Authentication

No key needed. Without one the call is limited to 30 requests a minute per IP; with a key it counts against the key's limits instead.

Parameters

Name	In	Type	Required	Description
`symbol`	path	string	yes	Exchange symbol, upper case (BRK.B, not BRK-B). Lower case is accepted and upper-cased.

Request

curl "https://api.tradingpal.io/api/v1/demo/NVDA"

Response

JSON. The fields this route adds are below; every response also carries the envelope fields (api_version, as_of_session, data_version, source, disclaimer).

Field	Type	Description
`symbol`	string	The symbol asked for, upper-cased.
`available`	boolean	True when the nightly has a current candidate book for the symbol. False when the symbol is excluded from pattern analysis or no current book exists; setups is then empty.
`reason`	string · nullable	Why available is false, when the reason is known: not_covered means the symbol is excluded from pattern analysis. Absent when available is true, and when the nightly simply has no current book for the symbol.
`setups`	array of Setup	The current setups, one per eligible candidate. Empty when nothing is forming.
`stock_facts`	object · nullable	The ticker's Stock facts as the TradingPal screener's quick view shows them: price and moves, performance, momentum (EMAs, RSI, moving averages), volume and volatility, and the company. Ticker facts, so they come once per answer, not per setup. Null when the ticker has no current facts.
`stock_facts.as_of`	string · nullable	When the facts were read, for example "Facts as of the Oct 6 close."
`stock_facts.sections`	array of object	Groups in the quick view's order: Price, Performance, Momentum, Volume and volatility, and Company (Asset for crypto). A missing fact is left out and an empty group dropped.
`stock_facts.sections[].title`	string	The group's heading.
`stock_facts.sections[].rows`	array of object	The group's facts, in order.
`stock_facts.sections[].rows[].label`	string	For example "EMA8 vs EMA21" or "RSI (14)".
`stock_facts.sections[].rows[].value`	string	Ready to show, units included, for example "+2.5%", "$43B" or "59".
`stock_facts.sections[].rows[].tone`	string (enum)	up or down on signed price moves; absent on other facts. One of `up`, `down`.
`stock_facts.sections[].rows[].change`	string	Only on the Last row: the day's change, for example "+0.40%".
`stock_facts.sections[].rows[].change_tone`	string (enum)	up or down for change. One of `up`, `down`.
`demo`	boolean	True on the demo routes. Absent on the keyed route.
`next`	string · nullable	On the demo routes, a sentence saying where to get a key for other tickers. Absent on the keyed route.

Errors

Errors are JSON with the Error shape; the fix field says what to do.

Status	Code	Meaning	Fix
429	`rate_limited`	The key passed 60 requests in a minute or 10,000 in a day, or a keyless caller passed 30 a minute from one IP.	Wait `details.retry_after_seconds`, then retry. Cache the nightly answers; they do not change until the next session.
404	`not_a_demo_symbol`	The keyless demo answers only for its fixed set of large caps.	`GET /demo` lists the demo symbols. For any other ticker, use a key and track it.
