Built for agents and people

Research with an evidence contract.

GoodBoy gives an agent bounded SEC tools, stable machine-readable responses, exact filing links, coverage dates, and caveats that travel with every answer.

Start correctly

Use the job-level tool first.

01

Ownership change brief

Call get_ownership_activity to combine insider filings and institutional position changes without confusing their meanings.

02

Exact evidence

Keep the returned claims, filing URLs, release IDs, coverage, freshness, and caveats beside the conclusion.

03

Scoped access

Machine access uses a revocable pilot credential. The browser email gate is not an agent authentication method.

Discovery

Choose the interface your agent understands.

Non-negotiable interpretation

13F changes are not trades.

Form 13F shows quarter-end holdings. GoodBoy reports new, exited, increased, or decreased positions and labels the comparison as unadjusted. Only insider code P is a purchase and code S is a sale.
