Deribit option market summary for BTC, ETH or SOL: put/call open-interest and volume ratios, max-pain strike and ATM mark implied volatility for the nearest expiries. Computed from Deribit's public book summary. No 25-delta skew (needs per-option greeks, not fetched) and no order flow.

Keyword discussion velocity on Hacker News (Algolia HN Search, public): stories in the last 24 hours, stories in the last 7 days, velocity (24h count vs. 7-day daily average) and the top 24h stories with points and comments. Only Hacker News: Reddit and Bluesky blocked automated requests in testing, and no sentiment score is given.

PASS / CAUTION / AVOID verdict for an EVM token (Base, Ethereum, BSC, Arbitrum, Polygon) from GoPlus token security (honeypot flag, buy/sell tax, open source, proxy, top holder share) and DexScreener (deepest pair liquidity, 24h volume). Rules are fixed and listed in the answer. Not financial advice; Solana is not covered.

Ethereum wallet profile from Blockscout: ETH balance, contract or EOA, ENS name, Blockscout scam flag and reputation, public tags, and activity over its most recent 50 transactions. NOT included: OFAC sanctions screening (the SDN list is 78 MB, too large per request), mixer (Tornado Cash) checks, and full wallet age.

Estimated current value of the token amounts a wallet received minus sent in its most recent 50 ERC-20 transfers (Blockscout), priced at current DefiLlama prices. It is NOT profit and loss: there is no cost basis, no historical prices, no realised gains, win rate or Sharpe ratio, and transfers older than the latest 50 are missing.

Large transfers on Ethereum in the latest 1 to 10 blocks (default 5, about one minute of chain time): native ETH transfers valued at the current ETH price, and USDT and USDC token transfers, each at least a USD threshold (default $100,000), with asset, amount, USD value, hash, block, sender and recipient. Ethereum only; other tokens are not included; a snapshot, not a live stream.

Static search of a VERIFIED Ethereum contract's Solidity source (Blockscout) for max-wallet, max-transaction and cooldown rules, with the matching lines. Unverified contracts are reported as such, not guessed. Bytecode-only and non-Ethereum chains are not covered; a hit is a clue, not proof of a trap.

Ethereum native-ETH balance snapshot of up to 10 wallets that a community label dataset (brianleect/etherscan-labels, GitHub) tags as Binance, Coinbase or OKX. It is a snapshot of a sample, not total exchange reserves: no token balances, no inflow or outflow history, and the labels are community-made and may be out of date.

Across bridge limits for USDC between two chains: the largest instant-fill amount the bridge can take right now, the largest deposit it accepts, and the smallest deposit. Across only (not Stargate, Hop or CCTP), USDC only, and the chain pair must be one the Across limits API accepts.

Ranks DeFi pools by total APY from DefiLlama's public yields data, filtered by chain, minimum TVL and optional stablecoin-only, with each pool's TVL, 7-day impermanent loss, reward share of APY and IL-risk flag. Ranking is by APY, not by safety: there is no audit or exploit-history score (none is in this free source).

Estimated output, price impact and minimum output for a swap in one DEX pair, using the pair's reserves from DexScreener and a constant-product (x*y=k) model with a fee. Exact for constant-product pools (for example Aerodrome volatile pools, Uniswap V2 style); for concentrated-liquidity pools (labelled v3 or v4) it is only an approximation. Raydium is not covered.

Registration facts for a domain from the public RDAP directory: registration date, age in days, expiry, registrar, lock status. No authority score, backlink or spam index: no free public source for those was found (Tranco rank API needs a key; DNS-over-HTTPS was unreachable from the test network).

Entity brief for a statement: finds up to 3 capitalised names or phrases in it and looks each up in Wikidata (public knowledge graph), returning the Wikidata ID, label, short description and link. It confirms the entities exist; it does NOT judge whether the claim is true, and it finds no numbers or dates.

Holder concentration for an EVM token (Ethereum, BSC, Base, Arbitrum, Polygon): share of supply held by the top 1, top 3 and top 10 holders, total holder count, and how much of the top 10 are contracts. GoPlus gives only the top 10 holders, so the top-20 view and funding-source clustering are NOT provided.

Share of a token's LP tokens that are burned (dead or zero address) or locked, from GoPlus lp_holders on Ethereum, BSC, Base, Arbitrum or Polygon. Lists the top 10 LP holders with GoPlus's lock flag and tag (a locker's name only when GoPlus gives it). Does not query Uncx, Team.Finance or Streamflow directly.

Compares a public page now with its earliest Internet Archive (Wayback) snapshot on or after a date: changed yes/no, word similarity, added and removed text lines, and the price-like amounts ($, €, £) before and after. Only what the archive captured is compared; pages the archive never saved return 404.

Latest BBC News headlines from one section feed (world, business, technology, science_and_environment, health, politics) with summary, link and publication time, optionally filtered by a keyword. BBC only: no other publishers, no entity tags and no trust rating (no free source for those was found).

Name screening against the US OFAC SDN list (with aliases, sanctions programs, type and addresses, via the US Consolidated Screening List API) and the UN Security Council consolidated list, returning matching entries. Optional fuzzy matching for the SDN part. It does NOT screen crypto addresses and does NOT check the EU list. A match is a lead for a human reviewer, not a legal decision.

Daily MVRV ratio (market cap / realized cap) for BTC or ETH from CoinMetrics' free community data, with the latest value, the window mean and standard deviation, and its z-score. Labels are plain statistics (HIGH_Z, LOW_Z, MID), not buy or sell calls. Realized cap in USD is not in the free tier, so only the ratio is returned.

Masks likely secrets and personal data in agent logs or chat text: 0x private keys (64 hex), labelled base58 private keys, JWTs, AWS access key ids, common API token prefixes (sk-, ghp_, xoxb-), payment card numbers that pass the Luhn check, and email addresses. Returns the redacted text and counts. Pattern-based: it can miss unusual formats and does not detect seed phrases or names.

Solana SPL token mint audit from the public Solana RPC: is the mint authority revoked (no more minting), is the freeze authority revoked, supply and decimals. Metadata immutability is NOT checked (it needs a separate Metaplex lookup this tool does not do).

Current USD price and deviation from the $1 peg for USDT, USDC, DAI, FDUSD and PYUSD (CoinGecko public price data). Flags MICRO_DEPEG at 0.15% or more and DEPEG at 1% or more. A single snapshot of CoinGecko's aggregate price: no per-pool Curve imbalance and no redemption-liquidity data.

Checks 2 to 10 Ethereum wallets for shared counterparties: addresses that several of them sent to or received from in their most recent 50 transactions (Blockscout). Reports the shared addresses and a POSSIBLE_CLUSTER signal. Recent-page only, no funding-source trace, so it finds some clusters and misses others.

For a brand domain (e.g. paypal.com), builds up to 15 look-alike variants (omitted, doubled and swapped letters, 0/1 homoglyphs, hyphen and login additions, other TLDs) and checks which are registered, using the public RDAP directory. Registered means taken, not malicious: each one needs a content check. Unicode homoglyphs (IDN) are not generated.

Checks the named entities in an AI answer (up to 5 capitalised names) against Wikidata: each name is marked found or not found, with its Wikidata ID and description, and sentences containing a year are listed for review. It checks that entities exist, not that claims about them are true, so a found entity can still have a wrong fact.

Full-text search of US SEC EDGAR filings (SEC public index): matching filings with company name, CIK, form type (10-K, 10-Q, 8-K, 4 and others), filing date and a link to the filing index. Optional form type and date range; up to 10 results. Full-text only: no financial figures are extracted.

Recent US recalls matching a keyword: CPSC consumer-product recalls (saferproducts.gov, by recall date and description text) and FDA food enforcement reports (openFDA, reason for recall). Vehicle (NHTSA) and FDA drug/device recalls are not included.

Legal entity identifier (LEI) records from GLEIF's public database: search by legal name (up to 5 matches) or look up one 20-character LEI. Returns legal name, country, city, entity and registration status. Parent companies are not expanded here (a second request per entity would be needed).

Current wave height and period at a coordinate (Open-Meteo Marine), and, when a US NOAA tide station id is given, the next high and low tide predictions for the next 24 hours. Tide predictions exist only for NOAA stations; no wind or pressure forecast is included.

Parses an international phone number (E.164), checks it against Google's open libphonenumber metadata, and returns the country, line type (mobile, fixed line, fixed-or-mobile, VoIP, toll free, premium, pager and more), E.164/international/national formats and the carrier that the number range was originally allocated to. Not a live HLR query: ported numbers keep the original carrier and active/ina

Subdomain takeover check: lists up to 10 subdomains seen in certificate transparency logs for a domain (Cert Spotter), fetches each over HTTPS, and flags pages that show a known 'unclaimed service' message (GitHub Pages, S3, Heroku, Fastly). Looks at the page text only, not DNS records, so it can miss dangling records that show no such message.

Academy Sports + Outdoors products on one category page (for example fan-shop): product name, brand, price in USD, product link, image and manufacturer part number, read from the page's schema.org product list. First page of the category only.

Regular season or postseason, 2002 to now. ERA and WHIP sort lowest first. Data from ESPN's public stats API (Baseball-Reference blocks automated access).

Blockchair chain statistics for one blockchain (bitcoin, ethereum, litecoin, dogecoin, bitcoin-cash, dash, zcash, groestlcoin): block and transaction counts, mempool size and fees, 24-hour hashrate and volume, and the market price in USD as Blockchair reports it.
