How to authenticate

Checked against the endpoint by our probe on 24 Aug 2026. These are the capabilities the server advertises, not a prediction about any particular client.

Scheme	OAuth

Anonymous access	Handshake succeeds; 22 tools listable
Credentials demanded in prose	✕screen_companies These tools are listed anonymously and their own descriptions ask for an account or key, but no challenge is issued — so a client has nothing to act on and the refusal arrives as a tool error.

What the probe found

warningTools needing credentials are listed without a challenge

1 of the 22 tools listed anonymously say in their own descriptions that they need an account or a key (screen_companies), but the endpoint issued no WWW-Authenticate challenge. The requirement is stated only in prose, so a call reaches the tool and comes back as a tool error instead of an authorization step.

22 tools usable without signing in

The server exposes a public surface before authorization: browse_company, search_companies, get_company_overview, get_stock_price, get_financials, compare_companies, screen_companies, list_filings, get_filing_section, get_xbrl_facts, get_filing_index, screen_filing_signals, search_sec_filings, get_earnings, get_guidance_vs_actual, compare_earnings_calls, get_metric_history, get_metric_lineage, get_ir_documents, get_company_events, get_earnings_reports, list_recent_filings.
