Congressional stock trades from two coverage sources — a realtime cross-ticker feed (provider=options_flow, default) or a bulk alternative-data feed (provider=alternative_data) — with an optional ticker filter, each trade with the member's party (null when unknown). With provider=alternative_data and a ticker, trades come from a warehouse copy that holds trades from 2025-05-20 onward (earlier history for 114 tickers); data_from, history_floor and coverage_note say where the copy begins, so never call it the complete history. Both feeds add side (buy/sell/exchange), party_code, chamber_code and is_member_of_congress (false for an executive-branch filer), and owner (whose account: self, spouse, joint, child) where the feed states it. reported_date_basis says what reported_date is: on options_flow it is the day the source recorded the disclosure, which can trail the filing date by one to three days. Call this when the user asks what Congress members have been buying or selling, market-wide or in a specific name. A 503 means the feed could not be read, not that nobody traded; a ticker the security master does not carry is a 404 unknown_ticker.

A 200 is a JSON envelope: ok: true and this endpoint's own fields (see Congressional Trades). It carries X-Request-ID, the credit headers (X-Credits-Cost, X-Credits-Remaining, X-Credits-Receipt, X-Credits-Settlement) and the rate-limit headers.
A 200 is billed even when it holds no data (an empty list, null, found: false), so check those fields. Pricing & credits explains the credit headers.
Errors
No error is billed. The body is { "ok": false, "error", "detail", "request_; read the code from error.
| Error | Meaning |
|---|---|
400 invalid_ticker | The request is malformed, for example a ticker that is not a symbol: invalid_ticker, refused before any credit is reserved, with param naming the parameter. Not billed. |
401 unauthorized | Missing or invalid API key. |
402 plan_required | Your plan does not include this tool, you are out of credits, or your workspace's spend cap paused its keys. plan_required names the plan that unlocks the tool; usage_exceeded means the credit balance is spent; spend_cap_reached means the key is paused until the cap resets or is raised: detail names the cap and the reset, cap_usd and resets_at (ISO 8601) carry them, and doc_url links pricing and credits. Not billed. |
403 scope_denied | This API key is limited to some products and this tool is not one of them. product names the tool's product and scopes the key's products. An upgrade does not change it: use a key whose scopes include the product, or change this key's scopes. Not billed. |
404 unknown_ticker | No data source lists this ticker, active or delisted: the market-data listing and the security master both say it does not exist. param names the parameter. Not billed. Best-effort: it is answered only when the route itself found nothing, and after 20 lookups of new symbols per API key per minute the route's own answer stands. |
422 validation | A parameter is missing, out of range or the wrong type; param names it. Not billed. |
429 rate_limited | Your plan's rate limit is spent for this window. Retry after Retry-After seconds. Not billed. |
503 paid_ | The data could not be served completely right now; retry later. Not billed. |
504 request_timeout | The request ran past the server's time budget; retry. Not billed. |
