beta Standard

Most active congressional traders by number of disclosed trades.

GET /v1/us_congress_trades/stats_politicians

What you get#

A list of Us Congress Trades 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
`limit`	string	no	`25`	Rows to return (1-100)	max 3 chars; must match `[0-9]{1,3}`; trimmed

Request#

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
`memberKey`	`author.id`	-
`name`	`author.displayName`	-
`state`	`author.location`	-
`party`	`ext.party`	-
`tradeCount`	`author.contentCount`	`toNumber`
`volumeMid`	`ext.volumeMid`	`toNumber`
`latestTradeDate`	`ext.latestTradeDate`	`toIsoDate`
`rank`	`entity.stats.rank`	`toNumber`

Caching and freshness#

Fresh for about 5 minutes. Repeat calls in that window are served from cache and are free.
Between 5 minutes and 1 hour 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 day more (marked stale).
A "not found" is remembered for 2 minutes 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.
