Stock due diligence report — Due diligence on a US-listed company beyond the last numbers, all from its SEC filings: the trend over eight quarters (revenue growth against the same quarter a year before, gross, operating and net margins, inventory or receivables outgrowing sales, free cash flow against earnings), valuation (market cap, P/E, P/S from its Robinhood stock token price, when it has one), management's outlook quoted from the latest earnings release, the 8-Ks of the last 120 days (CEO changes, auditor changes, restatements, layoffs), dated catalysts ahead (the next earnings date estimated from last year's, debt …

Changed the definition of "bundle_check"
⟨95 unchanged words⟩ many of the biggest buyers were brand-new wallets. On Solana, earlyBought counts every buy (fast in-and-out trading can push it past 100%); heldAtWindowEnd is what they still held when the window closed. Use for 'is this bundled?', 'was the launch sniped?'.
Added "company_financials", "dilution_check", "filing_search" and 8 more (21 tools before, 32 now)
Company financials (SEC filings) — A US-listed company's reported numbers, from the financial data tagged in its SEC filings (10-K and 10-Q; not the reports' text, which is filing_text): revenue, gross and operating profit, net income, diluted EPS, operating cash flow, capital spending, free cash flow, R&D, cash, long-term debt, assets, liabilities, equity and share count, for the last few fiscal years or quarters, with growth and net margin, and its latest filings (10-K, 10-Q, 8-K with item numbers). Every value links to the filing it came from. Look a company up by ticker (AAPL), name or SEC CIK. Use for 'how is X doing', 'i…
Dilution check (SEC filings) — Is a company issuing, or set up to issue, new shares? From its own SEC filings: shares outstanding now vs 1 and 3 years ago, open shelf registrations (S-3, S-3ASR, F-3) and offerings (424B prospectus supplements) in the last 3 years, at-the-market (ATM) sales programs, unregistered share sales (8-K item 3.02), warrants outstanding, convertible debt, and room left under authorized shares. Each item links to its filing. Signs, not a verdict: a shelf allows selling, it doesn't mean shares were sold. Use for 'does X have dilution', 'is X diluting', 'does X have an ATM / shelf'.
Search every SEC filing (EDGAR full text) — EDGAR's full-text search across every SEC filing since 2001: which filings mention a phrase, by whom, when. Filter by form (10-K, 8-K, S-1, DEF 14A...), company and dates. Use quotes for an exact phrase ('"going concern"'), OR between alternatives. Returns the total, the top filers, and the matching documents with links. A match only means the words appear; read the passage with filing_text before saying what a filing says.

Added "prediction_market" and "prediction_markets" (19 tools before, 21 now)
One prediction market and its history (Polymarket) — One Polymarket market or event by its polymarket.com link, slug or market id: the Yes odds now, 24-hour and weekly change, spread, liquidity, volume, end date, the resolution rules, and the odds over the last day, week or month. For an event with several markets (like each Fed meeting), lists them all and charts the busiest unless the link names one. Read-only.
Prediction market odds (Polymarket) — Search Polymarket's open prediction markets by topic. Use short, neutral topic words, the way a market would be named: 'House 2026' or 'which party wins the House', not 'Republicans lose the House'; 'Fed rate cut', 'bitcoin November'. Results are in Polymarket's relevance order with each event's volume: the headline market on a topic usually has by far the most volume, so if none of the results answers the question directly, search again with other words. For each event: its markets with the Yes odds in percent, the change over 24 hours and a week (in points), volume, liquidity, the date it c…

Also takes a Solana mint (pump.fun and other launches): there, linked also means funded by the same wallet shortly before buying, funded by the dev, bought in one transaction or paid each other's fees, and it says how many of the biggest buyers were brand-new wallets. Use for 'is this bundled?', 'was the launch sniped?'.Robinhood Chain only for now.

What a filing says (SEC) — The text of a company's SEC filing, or one section of it: a 10-K's or 10-Q's risk factors, legal proceedings, management's discussion (MD&A), business or cybersecurity; what an 8-K announced (and its exhibits, like the EX-99.1 press release); a proxy's (DEF 14A) executive pay; an S-1. Pass a section by plain name ('risk factors', 'legal proceedings', 'MD&A') or item ('item 1a', 'item 2.02'), and/or a query to get just the passages that mention it ('going concern', 'customer concentration'). Defaults to the latest 10-K. Long sections come in pages (offset). Every result links to the document. …
Fund holdings (SEC 13F) — What an investment manager (a hedge fund, Berkshire Hathaway, any manager with $100M+ in US stocks) held at the end of its latest quarter, from its 13F filing: top positions by value with share of portfolio, total value, and what changed since the quarter before (new positions, added, trimmed, sold out). Look a fund up by its manager's legal name ('Pershing Square Capital', 'Berkshire Hathaway', 'Scion Asset Management') or SEC CIK. 13F data is quarterly, filed up to 45 days after the quarter ends, and shows long US positions only.
Insider trades (SEC Form 4) — What a US-listed company's executives, directors and 10% owners bought and sold, from their Form 4 filings: who (name and role, as filed), when, what kind of trade (open-market buy or sale, option exercise, grant, shares withheld for tax, gift), shares, price, value, holdings after, and whether a sale was under a pre-set 10b5-1 plan. Sums open-market buys and sales. Each filing links to the SEC. Use for 'are insiders selling X?', 'did the CEO buy?'.
Stop watching a wallet (paid) — Remove a wallet from your watchlist (its label goes with it). Needs your agent key.
What a wallet did (transfer by transfer) — Every token transfer in or out of a wallet over the last hours, newest first, across Robinhood Chain, Base, Ethereum, Arbitrum and HyperEVM: time, chain, in or out, token, amount, USD at today's prices, the counterparty, and a link to the transaction. Free, for a one-off look at any wallet. To keep a list of wallets with private names and get what changed since you last checked, use the paid watch_wallet and watched_events.
Watch a wallet (paid) — Add a wallet to your watchlist with a private name ("Treasury", "Dev wallet of XYZ"), or rename one already on it. Labels are private to your agent key. Then watched_events tells you what your wallets did since you last checked. Paid: needs an agent key from https://fivebar.xyz/x402/watch/watch10 ($5, 10 wallets, 30 days) or watch50 ($20, 50 wallets), sent as Authorization: Bearer <key>.
What your watched wallets did (paid) — What the wallets on your watchlist did since you last checked each one (or the last hours you ask for), labelled with your names: transfers in and out, tokens, amounts, USD at today's prices, counterparties and links. Five wallets per call; pass offset for the next five. Marks them checked. Needs your agent key.
Your watchlist (paid) — The wallets you watch, with your private labels, chains and when you last checked each, and your plan (wallets allowed and used, when it ends). Needs your agent key. Without one, says how to get it.

Get your own wallet (to trade and pay) — No wallet yet, or not sure how to sign? How an agent gets its own wallet on its own computer, backs it up with its human, and trades through Fivebar: install the Fivebar Wallet (a small local MCP, `npx -y fivebar`) that creates the key on your computer, makes your human confirm a backup before any money moves, then signs swap_build's transactions and x402 payments there. Or bring a wallet you already have. Fivebar never sees or holds your key.
