finance.markets

stable Standard

Market movers for the day (biggest gainers, biggest losers or most active stocks).

GET /v1/finance/markets

What you get#

A list of Finance results in Onekey's unified shape, in data (an array). An empty array is a normal, successful answer and is charged like any other; a source that reports "nothing found" as an error returns a free 404 not_found instead.

What it costs#

Standard · 1 credit for a fresh fetch, charged only when it succeeds.
Free when served from cache (0.2 credit for a cached response over 100 KB).
Free if the request is invalid (never charged) or the source fails or reports not found (refunded).

Parameters#

Name	Type	Required	Default	What it is	Constraints
`screen`	string	no	`day_gainers`	Which list: day_gainers, day_losers or most_actives	max 12 chars; must match `day_gainers\|day_losers\|most_actives`; trimmed, lowercased
`n`	string	no	`25`	Rows (1-50)	max 2 chars; must match `[1-9]\|[1-4]\d\|50`; trimmed

Field mapping#

How this endpoint's source fields become Onekey's unified schema. Fields the source lacks come back as null.

Source path	Onekey field	Transform
`symbol`	`market.symbol`	-
`longName`	`entity.name`	-
`quoteType`	`entity.category`	-
`fullExchangeName`	`market.exchange`	-
`currency`	`market.currency`	-
`regularMarketPrice`	`market.price`	`toNumber`
`regularMarketChange`	`ext.change`	`toNumber`
`regularMarketChangePercent`	`ext.changePercent`	`toNumber`
`regularMarketVolume`	`market.volume`	`toNumber`
`marketCap`	`market.marketCap`	`toNumber`
`regularMarketTime`	`entity.date`	`toIsoDate`

Caching and freshness#

Fresh for about 30 seconds. Repeat calls in that window are served from cache and are free.
Between 30 seconds and 5 minutes the cached copy is still served instantly and marked stale: true while Onekey refreshes it in the background.
If the source is down when a refresh is needed, the last copy can be served for up to 1 hour more (marked stale).
A "not found" is remembered for 1 minute and is free.
The cache is shared across all customers, which is what keeps repeat calls cheap.

What can go wrong#

Status	Code	What to do
401	`unauthorized`	Check the `x-api-key` header.
402	`insufficient_credits`	Add credits; your balance must cover the price.
404	`not_found`	Unknown endpoint path.
422	`invalid_params`	Fix the parameters using the table above. Free.
429	`rate_limited`	Wait `Retry-After` seconds, then retry.
502	`upstream_error`	The source failed. Refunded; retry with backoff.

See Errors for the full list and retry guidance.

Status: stable (verified against the live source).
