us_congress_trades.trades

beta Standard

Latest disclosed US Congress stock trades (newest first), by chamber.

GET /v1/us_congress_trades/trades

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.

Also known as: /us_congress_trades/trades/latest, /us_congress_trades/trades/recent on APIs that nest their paths. See Alternatives and equivalents.

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).

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`	-
`transactionDate`	`content.createdAt`	`toIsoDate`
`disclosureDate`	`content.updatedAt`	`toIsoDate`
`type`	`content.type`	-
`amount`	`ext.amountRange`	-
`assetDescription`	`content.title`	-
`lastName`	`author.displayName`	-
`firstName`	`author.username`	-
`office`	`ext.office`	-
`owner`	`ext.owner`	-
`link`	`content.url`	`safeUrl`

Caching and freshness#

Fresh for about 2 minutes. Repeat calls in that window are served from cache and are free.
Between 2 minutes and 15 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.
