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 closes (not the event's own date), status, and a link. Markets with a wide spread or little liquidity are marked thin. Read-only market prices from Polymarket's public API, not forecasts or advice. Use for 'what are the odds of...', 'will X happen?', 'what does Polymarket say about...'. Then prediction_market for one market's history.

stock_reportaddedDue 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 coming due, buyback left, shelf expiry, annual meeting), and what to watch (risk factors added in the latest 10-K, customer concentration, going-concern language). Each item links to its filing. Use for 'do DD on X', 'what are the catalysts for X', 'what should I watch on X'. Premium: 10¢ a call from prepaid agent credits (3 free premium calls a day). Send your agent key as Authorization: Bearer <key>.
dilution_checkchangeddescriptionIs 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, the latest 424B5s read for their terms (ATM maximum, shares and price, warrants, how much the offering dilutes, each with the sentence it came from), 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'.

dev_checkchangeddescriptionThe wallet that launched a token and what it did since: when it launched, how much it received, how much it still holds, how much it sold (how many sells, when, and roughly what that's worth), which wallets it sent tokens to and what they hold now. Tokens on Robinhood Chain, Ethereum or Base, or a Solana mint (the dev is whoever paid to create the mint; sells are in SOL). Use for 'is the dev selling?', 'did the dev dump?', 'who launched this?'. To see where the dev's money went on Robinhood Chain, follow up with wallet_flows on the deployer. Works for 0x tokens on Robinhood Chain, Ethereum and Base (pass chain, or it finds the chain); on Ethereum and Base the dev is whoever created the token's contract, and a very busy token is read from its most recent transfers.

bundle_checkchangeddescriptionWho bought a token in the first 60 seconds after trading opened: how many wallets, what share of supply they took and still hold, how many bought in the very block trading opened, and which early buyers are linked to each other or to the dev. 0x tokens on Robinhood Chain, Ethereum or Base (pass chain, or it finds it): linked means they moved the token between them. 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. 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?'.

token_reportchangeddescriptionThe full check on a Robinhood Chain token in one call: the safety check (can you sell it, taxes, owner), price and pool depth, who holds it and which holders are linked, whether the launch was bundled, and what the dev did. Returns one verdict (high, caution or low) with the reasons behind it, each tagged with its section, plus a one-line summary per section. Use this first for 'is this token safe?', 'should I worry about this token?', 'check this token'. Use token_holders, bundle_check or dev_check for more detail on one part. Robinhood Chain only for now.

wallet_flowschangeddescriptionWhere a wallet's money came from and where it went over the last days, on Robinhood Chain (default), HyperEVM, Base, Ethereum or Arbitrum: every counterparty that sent it or received tokens from it, grouped and priced in USD (today's prices), with transfer counts, the tokens moved and first and last dates. Counterparties are marked wallet or contract, and labelled when they're registered ERC-8004 agents or well-known contracts (never people).

agent_lookupread-only | Look up an AI agent on Robinhood Chain by ERC-8004 agent ID, wallet address or name: its owner and agent wallet, Fivebar Score (as a seller: how many independent operators pay it, with bundled buyer wallets counted once; as a buyer: how many real sellers it pays; 'not scored yet' with progress when the evidence is thin, never a 0), screened x402 record (passed, not counted yet, removed for wash patterns), flags and clusters.

check_sellerread-only | Before paying an x402 seller on Robinhood Chain, check its address against Fivebar's wash screen: whether it's among the sellers whose payments passed in the last 24 hours, its buyers and volume, and its agent record if it's a registered agent. |
company_financialsread-only | 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', 'is X profitable', 'how much debt does X have', due diligence on a public company. Only companies that file with the SEC; not private companies or crypto projects. |

Tokens on Robinhood Chain, Ethereum or Base, or a Solana mint (the dev is whoever paid to create the mint; sells are in SOL). Use for 'is the dev selling?', 'did the dev dump?', 'who launched this?'. To see where the dev's money went on Robinhood Chain, follow up with wallet_flows on the deployer.

filing_searchread-only | 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. |

Defaults to the latest 10-K. Long sections come in pages (offset). Every result links to the document. Quote the filer's words. |
fund_holdingsread-only | 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. |

Sums open-market buys and sales. Each filing links to the SEC. Use for 'are insiders selling X?', 'did the CEO buy?'. |
perp_quoteread-only | One Hyperliquid perpetual market by coin (e.g. BTC, ETH, HYPE): mark and oracle price, 24h change, funding, open interest, volume and max leverage. |
perps_marketsread-only | Perpetual futures markets on Hyperliquid: mark price, 24h change, funding (hourly and yearly), open interest, 24h volume and max leverage. Sort by volume, open interest or funding; filter by coin. |
prediction_marketread-only | 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_marketsread-only | Search Polymarket's open prediction markets by topic.

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 closes (not the event's own date), status, and a link. Markets with a wide spread or little liquidity are marked thin. Read-only market prices from Polymarket's public API, not forecasts or advice. Use for 'what are the odds of...', 'will X happen?', 'what does Polymarket say about...'. Then prediction_market for one market's history: pass the market's `ref`. |
stock_quoteread-only | Price of a Robinhood stock token on Robinhood Chain, by symbol (e.g. AAPL) or token address: the Chainlink feed price per token (dividends and splits included through the multiplier), how fresh it is, the on-chain DEX price where a Uniswap pool exists, and which sessions it trades in. Equity feeds follow US market hours 24/5 and hold their last price when markets are closed. |
stock_reportread-only | 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 coming due, buyback left, shelf expiry, annual meeting), and what to watch (risk factors added in the latest 10-K, customer concentration, going-concern language). Each item links to its filing. Use for 'do DD on X', 'what are the catalysts for X', 'what should I watch on X'. Premium: 10¢ a call from prepaid agent credits (3 free premium calls a day).

stocks_listread-only | List the tokenized stocks Robinhood issues on Robinhood Chain (about 100: AAPL, TSLA, NVDA...): symbol, name, token address, shares-per-token multiplier, which trading sessions they trade in, and whether a Chainlink price feed exists. Filter with query (symbol or name). |
swap_buildread-only | Build a swap for your own wallet to sign and send, on Robinhood Chain, HyperEVM, Base, Ethereum, Arbitrum or Solana. Returns a firm quote (amount out, minimum, every fee) and the unsigned transactions in order. EVM chains: an exact-amount approval when needed, then the swap. Solana: one versioned transaction (base64) your wallet pays for and signs. Fivebar's 0.5% fee is paid inside the swap; Fivebar never sees your keys or holds your funds. Wallets on the US sanctions list are refused. xStocks are coming soon. |
swap_quoteread-only | What swapping one token for another would give right now, on Robinhood Chain (default), Solana (SOL, USDC, USDT and memecoins by mint address; picked automatically for those), HyperEVM (HYPE, WHYPE, USDT0, USDC or a token address; pass chain hyperevm), Base, Ethereum or Arbitrum (ETH, WETH, USDC, USDT or a token address; pass chain). EVM chains: the best route across Uniswap v2/v3/v4, PancakeSwap, SushiSwap, Aerodrome, Curve and other DEXes. Solana: the best route across Solana DEXes. Routed by 0x, with the amount out and the minimum after slippage, the USD value, and every fee shown separately (Fivebar's 0.5%, the router's fee where it applies, and network gas). Flags token taxes and, if you pass your wallet as taker, a missing balance or approval. xStocks are coming soon: use stock_quote for their prices. Quote only: nothing is signed or sent; to swap, use swap_build. |
token_holdersread-only | Who holds a token and how the holders are connected: the top 40 holders with their share of supply, marked pool (venue), dev, contract or wallet, and clusters of wallets linked by moving the token between themselves (one sent tokens to another).

Also takes a Solana mint: its 20 largest holders by owner, marked wallet, pool (labelled pump.fun, PumpSwap, Raydium, Orca or Meteora when known) or contract; linked wallets aren't read on Solana yet. Works for 0x tokens on Robinhood Chain, Ethereum and Base (pass chain, or it finds the chain); on Ethereum and Base the dev is whoever created the token's contract, and a very busy token is read from its most recent transfers. Premium: 2¢ a call from prepaid agent credits (3 free premium calls a day). Send your agent key as Authorization: Bearer <key>. |
token_quoteread-only | Price and market cap of any token by its contract address. A 0x address is read on Robinhood Chain by default (Uniswap v3 and v4 pools; when the best pool is thin, under $2,000 in range, or missing, the price comes from a $10 buy routed by 0x and a warning says so); pass chain hyperevm, base, ethereum or arbitrum for those chains. A Solana mint is priced from a small USDC buy routed across Solana DEXes. |
token_reportread-only | The full check on a Robinhood Chain token in one call: the safety check (can you sell it, taxes, owner), price and pool depth, who holds it and which holders are linked, whether the launch was bundled, and what the dev did. Returns one verdict (high, caution or low) with the reasons behind it, each tagged with its section, plus a one-line summary per section. Use this first for 'is this token safe?', 'should I worry about this token?', 'check this token'. Use token_holders, bundle_check or dev_check for more detail on one part. Robinhood Chain only for now. Premium: 5¢ a call from prepaid agent credits (3 free premium calls a day). Send your agent key as Authorization: Bearer <key>. |
token_riskread-only | What could go wrong buying a token, by contract address, on Solana, Robinhood Chain, HyperEVM, Base, Ethereum or Arbitrum. Solana: whether someone can still mint more or freeze holders, Token-2022 traps (transfer fees, a permanent delegate, transfer hooks), and how concentrated the top holders are. EVM: buy and sell taxes and whether the contract still has an owner. Both: a $100 buy-then-sell test through the router (can you sell it, and what's lost). Returns a verdict (high, caution or low) and the reasons. Not a guarantee. |
unwatch_walletread-only | Remove a wallet from your watchlist (its label goes with it). Needs your agent key. |
wallet_eventsread-only | 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. |
wallet_flowsread-only | Where a wallet's money came from and where it went over the last days, on Robinhood Chain (default), HyperEVM, Base, Ethereum or Arbitrum: every counterparty that sent it or received tokens from it, grouped and priced in USD (today's prices), with transfer counts, the tokens moved and first and last dates. Counterparties are marked wallet or contract, and labelled when they're registered ERC-8004 agents or well-known contracts (never people). Also the first money in within the window, often what funded it. Use to trace a deployer's sells, a seller's buyers, or where funds were sent. Premium: 2¢ a call from prepaid agent credits (3 free premium calls a day). Send your agent key as Authorization: Bearer <key>. |
wallet_holdingsread-only | Every token a wallet holds, with USD values, across Robinhood Chain, HyperEVM, Base, Arbitrum and Ethereum for a 0x address (or one chain with chain), or on Solana for a Solana address. Includes ETH, HYPE or SOL, stablecoins, Robinhood stock tokens and memecoins. Values: $1 for stablecoins, the ETH or HYPE price for the native token and its wrapped form, Chainlink for stock tokens, Uniswap pools on Robinhood Chain (a router buy when the pool is thin), a small buy routed by 0x elsewhere. The biggest positions carry a quick risk verdict (run token_risk for the full check). Tokens that look like airdropped spam are hidden and counted; tokens with no route to sell are listed apart. If the router is busy, a holding is valued from its last good quote (at most 15 minutes old) and marked priceAsOf. |
wallet_setupread-only | 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. |
watched_eventsread-only | 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. |
watched_walletsread-only | 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. |
watch_walletread-only | 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>. |
x402_statsread-only | Fivebar's index of x402 payments (USDG transferWithAuthorization) on Robinhood Chain: the last 24 hours and recent days, screened before they count. Volume that doesn't pass is split two ways: flaggedUsd shows a wash pattern (a seller paying itself, circular payments, two wallets paying 90%+ of a seller); tooFewBuyersUsd only went to sellers with under 10 distinct buyers, which isn't evidence of washing, just not enough to judge yet. topSellers lists sellers that passed. Updated every 3 hours. |
