For agents
Point your agent at ground truth
There's no dashboard to learn. Your agent connects once, then queries institutional money flow on your behalf, and every answer comes back with its receipts.
- 1
Connect in one step
Add the MCP server to Claude or any client, or call the REST API with a bearer token.
- 2
Ask in plain language
Your agent picks the right tools (lookups, search, time-series, cross-source joins) and chains them.
- 3
Get sourced data back
Every field returns with its source, timestamp, and a canonical URL to verify.
- 4
Cite, don't hallucinate
Your agent answers with grounded numbers and links straight back to the primary source.

Provenance
Every datapoint has receipts
We do the ugly work: pulling filings at scale, resolving identifiers, merging amendments, keeping every quarter point-in-time. The receipt comes along so you never have to take our word for a number. Any field unwinds to the official record it came from.
The value your agent cites, point-in-time, never silently restated.
The regulatory filing the row came from, with its filing date.
Every record has one. Here, the SEC accession number, carried on every row.
One click to the official record, so any claim can be checked without trusting us.
Supported records expose source metadata inline, with full lineage available through provenance.get.
