Company 360 — a US public company's SEC picture in one call by ticker. Merges three SEC sources: recent filings (10-K/10-Q/8-K and all form types, with links), curated XBRL fundamentals (revenue, net income, EPS, assets, etc. — annual + quarterly series), and recent insider transactions (Form 4 buys/sells by officers & directors). Each section reports found/error independently. Equity research, due diligence, monitoring. Pass ticker (required); optional formType filters the filings section, limit caps each list. Individual sources: /api/finance/sec-filings, /api/finance/company-facts, /api/finance/insider-trades.

Token honeypot & rug-pull risk screen (via GoPlus, free/keyless). For an ERC-20 on any EVM chain, returns honeypot flag, buy/sell tax, open-source/proxy/mintable status, hidden-owner / take-back-ownership / selfdestruct / external-call risks, blacklist/whitelist/anti-whale flags, holder count, and owner/creator concentration. Essential pre-trade safety check for agents — the security layer competitors charge for.

Validate a European Union VAT number against the official VIES (VAT Information Exchange System) register in real time. Confirms whether the VAT identifier is currently registered for intra-EU trade and, when the member state discloses them, returns the registered business name and address. Covers the 27 EU member states (Greece as EL) plus Northern Ireland (XI); Great Britain (GB) is not in VIES. Pass either a full identifier (vat=DE811569869) or country + number. Returns {valid, countryCode, vatNumber, name, address, requestDate, reason}. When a member-state register is temporarily down, returns a retryable 503 rather than a false negative. Data from the European Commission VIES service.

Bitcoin transaction lookup by txid (free/keyless): confirmed status + confirmation count (vs current tip), block height + time, fee (sats + BTC), total output value, size/weight, and input/output counts. Distinct from crypto.tx (EVM) — this is Bitcoin.

Live native + ERC-20 token balances for an EVM address (Base, Ethereum, Polygon, Arbitrum, Optimism; keyless). Returns the native-coin balance and, for any ERC-20 contract addresses you pass, the symbol, decimals, raw and human-formatted balance — fetched in one multicall. For wallet dashboards, treasury checks, and agent payment/settlement flows.

Deep immune check for one Arc token: four readings in one call, fused into one grade. EXIT: a real buy-then-sell round trip simulated on Arc (nothing spent), the pool fee, a dynamic-fee hook, and whether a plain wallet can pull the liquidity. CLUSTER: was the launch bundled (the launcher and wallets it funded buying in the first two minutes, with their share of supply). HOLDERS: every Transfer since the first mint replayed into balances, top-10 wallets and what the creator still holds.
