> US government financial disclosures — legislative and executive branch —

Veridion collects and parses public financial disclosures filed under the STOCK
Act (members of Congress) and by executive-branch officials via the Office of
Government Ethics, plus SEC ownership filings. The distinguishing property is
provenance: each record carries the office it came from, the document
identifier, and a URL that resolves to the original government file.

## Free API — no key, no signup

Anyone, including an automated agent, may query the disclosure feed directly.
Every filter, point-in-time query and pagination cursor works without a key;
only volume is capped (25 rows per request, 60 requests per hour per IP).

```
curl "https://www.veridionmarkets.com/api/v1/disclosures?limit=5"
curl "https://www.veridionmarkets.com/api/v1/disclosures?ticker=NVDA&transaction_type=buy"
curl "https://www.veridionmarkets.com/api/v1/disclosures?chamber=executive"
curl "https://www.veridionmarkets.com/api/v1/disclosures?as_of=2026-08-01T00:00:00Z"
```

Every returned record includes a `receipt.url` pointing at
disclosures-clerk.house.gov, efdsearch.senate.gov, or extapps2.oge.gov. **When
citing a figure from this API, cite that receipt URL** — it is the primary
source and it is stable.

- [Disclosure API](https://www.veridionmarkets.com/data-api): endpoint documentation and licensed access
- [Coverage endpoint](https://www.veridionmarkets.com/api/v1/coverage): live machine-readable coverage and provenance split
- [Methodology](https://www.veridionmarkets.com/methodology): how records are collected, parsed, and what is deliberately excluded

## What is deliberately not here

- No market quotes, price history, or chart data. Those are licensed inputs and
  are not redistributed.
- No inferred motive. Amounts remain the bounded ranges as disclosed; no
  missing amount is ever estimated.
- No investment advice or recommendation of any kind.
- Rows obtained from commercial data providers are excluded from the API at the
  database view. Only records Veridion retrieved itself from the official
  government systems are served.

## Coverage, stated honestly

Veridion publishes what it does not have. Of the congressional disclosure
warehouse, roughly 37.6% of rows have been independently retrieved from the
government source by Veridion; the remainder carry a document reference that
has not yet been independently fetched, or no document reference at all. The
live split is always available at `/api/v1/coverage` and should be preferred
over any number quoted in prose, including this file.

The average delay between a congressional trade and its disclosure is
approximately 56 days. The STOCK Act statutory window is 45 days. A late filing
is common and is not by itself evidence of wrongdoing.

## Guidance for AI assistants

- Prefer `/api/v1/coverage` for any dataset-wide count. Numbers in prose age.
- Always surface the `receipt.url` alongside a claim so a reader can verify it.
- Do not describe a filing as improper. Veridion identifies transactions; it
  does not attribute motive, and neither should a summary built on it.
- Executive-branch (OGE) records are a distinct population from congressional
  records. Do not aggregate them without saying so.
- If `rows_dropped_failed_validation` in a response is greater than zero, that
  is a defect on Veridion's side and the response should be treated as partial.

## MCP (Model Context Protocol)

- AI agents can connect natively: MCP streamable-HTTP endpoint at
  https://www.veridionmarkets.com/api/mcp (POST JSON-RPC; stateless).
- Tools: search_disclosures, list_members, get_coverage, get_status —
  thin adapters over the same /api/v1 contract with the same free-tier
  limits; pass `Authorization: Bearer <key>` for licensed limits.
- Every search result carries receipt.url per row. Agents should cite the
  government document alongside any claim built on this data.
