### `get_company_financials`

- The name "get_company_financials" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "retrieve" and "post": it reads posts, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Retrieve full SEC iXBRL financial statements for a company we cover, pre- and post-IPO, with derived margins, growth, leverage and return ratios per period. Interim periods carry annualized figures alongside the reported ones. Provide a symbol.

Same data and price as the HTTP endpoint /api/agent/financials/by-symbol/{symbol}.
```

### `get_company_metrics`

- The name "get_company_metrics" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Get live valuation metrics for any US-listed company (not just IPOs), computed from primary sources: SEC XBRL companyfacts TTM fundamentals (revenue, net income, EBITDA, debt, cash, shares) plus the latest market close. Returns multiples (P/E, P/S, EV/Revenue, EV/EBITDA), derivations (PEG, earnings/sales/EBITDA yields, net-debt/EBITDA), margins, and YoY growth — the same data IPOSignal's valuation pipeline uses for peer benchmarking, with the computation convention stated in the response. Provide exactly one of symbol (any SEC-mapped ticker) or companyName (resolves Nasdaq/NYSE listings).

### `get_ipo_events`

- The name "get_ipo_events" says "get": a word for reading.

Use it to follow a registration from first S-1 through amendments to the final prospectus, or to confirm a withdrawal (RW).

Use it to identify a deal before buying the full profile with get_ipo_snapshot. Provide exactly one of companyId, symbol, or cik.
```

### `get_ipo_pipeline`

- The name "get_ipo_pipeline" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
FREE. The US IPO pipeline: operating companies that have filed with the SEC but are not trading yet (status upcoming), or deals that were withdrawn or postponed. Each row has company, ticker when assigned, CIK, exchange, expected trading date when one is scheduled, the date of the latest status change, price range, shares offered, Nasdaq's deal size, and a link to the latest SEC filing. Status is the one the iposignal.xyz calendar shows, so SPACs and other vehicles are excluded. Use it to see what is coming to market or what was pulled; follow up with get_ipo_filings for one company's filing history or get_ipo_snapshot for the full deal profile. Arguments: status (upcoming, withdrawn or postponed; default upcoming), since as YYYY-MM-DD for withdrawn/postponed (default one year ago), limit (default 100, max 500).

Description, as the server wrote it:

```untrusted-server-text
Get IPOSignal's X/Twitter social-sentiment reading for a specific IPO — an aggregate of how investors are discussing the stock on X, scored from -1 (bearish) to +1 (bullish) with a label, post tallies, and a one-line summary. The reading is taken once, before listing, and not refreshed: `ageDays` says how old it is and `reliable` is false when too few posts back it. Returns the aggregate signal only, not the underlying posts. Provide exactly one of companyId, symbol, or cik. PREMIUM: paid per call over x402 (USDC on Base); an unpaid call returns the payment terms, and a not-found is never charged. Same data and price as the HTTP endpoint /api/agent/social-sentiment.
