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.

Live on-chain token metadata for an ERC-20 or ERC-721 contract (Base, Ethereum, Polygon, Arbitrum, Optimism; keyless). Returns name, symbol, decimals, detected standard, and total supply (raw + formatted). The authoritative read straight from the contract — complements crypto.token-price and crypto.contract (ABI/source).

Live ERC-721 NFT read (Base, Ethereum, Polygon, Arbitrum, Optimism; keyless). Given a contract + tokenId: returns current owner, collection name/symbol, and tokenURI (IPFS auto-resolved to a gateway URL). Pass metadata=1 to also fetch and normalize the token's JSON metadata (name, description, image, attributes). For NFT provenance, ownership checks, and gallery rendering.

The "kimchi premium" — how much higher a crypto asset trades on Korean exchanges (Upbit, KRW) than its global USD price, as a percent. Computed as (Upbit KRW price / (global USD price × USD/KRW)) − 1. Pass symbol = ticker(s), comma-separated up to 10 (default BTC); supported majors include BTC, ETH, XRP, SOL, DOGE, ADA, TRX and more. Returns per symbol { krwPrice, usdPrice, usdKrw, globalUsdInKrw, premiumPct }. Per-symbol resilient (one unlisted symbol does not fail the rest); unresolved symbols are reported in meta.errors. Live blend of Upbit (KRW price) + CoinGecko (global USD) + ECB/Frankfurter (USD/KRW FX).

Centralized-exchange 24h ticker for a spot pair (e.g. BTC-USD), free/keyless: current price, best bid/ask, 24h open/high/low, 24h + 30d volume, and 24h percent change. Real CEX spot quote — distinct from crypto.token-price (CoinGecko aggregate).

Centralized-exchange OHLCV candlesticks for a spot trading pair (e.g. BTC-USD, ETH-USD, SOL-USD), free/keyless. Pass interval (1m/5m/15m/1h/6h/1d) and limit. Each bar: time, open, high, low, close, volume. Net-new vs crypto.dex-ohlcv (on-chain DEX) — this is CEX spot.

Cross-walk an industry classification code across the four major systems: NAICS <-> SIC <-> ISIC Rev.4 <-> NACE Rev.2. Pass the system + code and get the equivalent code(s) in every other system, with official titles where available, plus the vintage of each table used. The deterministic join that lets a KYC, procurement, ERP, or cross-border-reporting agent translate "what industry is this" between the US (NAICS/SIC), international (ISIC), and EU (NACE) standards. Backed by bundled public-domain Census concordances (NAICS<->SIC: 1997 NAICS <-> 1987 SIC; NAICS<->ISIC: 2012 NAICS <-> ISIC Rev.4) and the UNSD ISIC Rev.4 <-> NACE Rev.2 correspondence. Multi-hop links (e.g. SIC->NACE via NAICS->ISIC) are derived and explicitly flagged in notes. SIC is a retired US system; there is no newer NAICS<->SIC table.

Polymarket crypto up-or-down markets — the recurring 'Will <asset> be up or down by <time>?' series for BTC, ETH, SOL, SPX and more (hourly/daily). Each event returns its question, dates, USD volume, and the nested Up/Down markets with live outcome prices (implied probability the asset closes higher). Filter count with limit. Read-only mirror of Polymarket's up-or-down tag.

Polymarket smart-wallet leaderboard: top traders ranked by realized volume or profit (P&L). Choose the time window (1d/7d/30d/all) and rankBy (vol/pnl); cap with limit. Each entry returns rank, wallet (proxy) address, trader name, X handle, verified badge, total USD volume, and USD P&L — for tracking smart money. Pair the wallet with predict.positions / predict.activity / predict.wallet. Read-only from Polymarket's Data API.

Sports prediction markets across Polymarket and Kalshi in one call — game lines, futures, and props (NFL/NBA/MLB/NHL/soccer/tennis/etc). Optionally narrow with league (a tag/category keyword, e.g. nfl, soccer, world-cup) and cap with limit. Each hit is tagged with its venue and returns the question, live YES/NO price (implied probability), USD volume, close date, and the venue URL. Read-only, keyless.

CISA Industrial Control Systems (ICS) advisories — vulnerabilities in operational-technology gear (SCADA, PLCs, building automation, energy/manufacturing/transportation systems, and medical devices), from the official CISA advisory RSS feed. Each item is normalized to the canonical advisory id (ICSA-YY-DDD-NN, or ICSMA-YY-DDD-NN for medical), title, link to the full advisory, publication date (ISO), and a plain-text summary. Optionally filter by keyword (e.g. a vendor like "Siemens") and cap the count. Returned newest-first. Free, public-domain (CISA).

NBA games from balldontlie — schedule and scores in one feed. Filter by season (start year), a single date, and/or team id. Each game: date, season, status, postseason flag, home/visitor teams and final (or live) scores. Cursor-paginated (pass meta.cursor as cursor to continue).

NBA players from balldontlie — search by name and page through results. Each player: id, name, position, height, weight, jersey number, college, country, draft year, and current team. Cursor-paginated (pass meta.cursor as cursor to continue).

NFL games from balldontlie — schedule and scores in one feed. Filter by season, week, and/or team id. Each game: date, season, week, status, postseason flag, venue, recap summary, home/visitor teams and final (or live) scores. Cursor-paginated (pass meta.cursor as cursor to continue).

Resolve SEC CIK <-> ticker in both directions. Pass a ticker to get its CIK; pass a CIK to get every ticker the issuer has (each share class, e.g. GOOG + GOOGL), each with its listing exchange (Nasdaq, NYSE, etc.) and the canonical company name. The CIK is the key to everything in EDGAR -- filings, XBRL facts, Form 4 insider trades, 13F holdings -- so this is the join that turns a ticker an agent has into the identifier EDGAR actually indexes by (and back). Data: SEC company_tickers_exchange.json (US public domain), cached and refreshed daily. Distinct from finance.security-resolve, which also crosses into FIGI/LEI/ISIN; this one is the focused, exchange-aware CIK<->ticker map.

Universal security-identifier resolver. Give exactly one of ticker, isin, or lei and get the others back — ticker, SEC CIK, FIGI (incl. composite + share-class), LEI, and ISINs — plus the canonical issuer name. The one call that joins a security across the systems agents actually use: CIK for filings, FIGI for trading, LEI for the legal entity, ISIN for settlement. Composes SEC EDGAR, OpenFIGI, and GLEIF (CC0). Per-source status is returned, so a partial match is explicit rather than silently wrong. Note: CUSIP/SEDOL are accepted by sibling /finance/figi as inputs but never emitted here (licensed); ISINs come from GLEIF CC0 data.

Resolve a US ZIP code to the census tract(s), county, CBSA (metro), and congressional district it covers — each with HUD-USPS allocation ratios (by residential, business, other, and total address counts). A ZIP is a mail-delivery route set, not a polygon, so it spans multiple geographies; the ratios tell you how much of the ZIP falls in each — the canonical join when you have a ZIP but a dataset is keyed by county/tract/district. Source: HUD-USPS ZIP Crosswalk (public domain).

HUD Income Limits (IL) for a US county or state — the program-eligibility thresholds for HUD assistance, derived from Area Median Family Income: extremely-low (30% AMI), very-low (50% AMI), and low (80% AMI) income limits for household sizes 1–8, plus the area median income. Look up by 5-digit county FIPS or by 2-letter state. Optional year (defaults to latest). The raw HUD il30/il50/il80 codes are reshaped into clear nested limits by household size. Source: HUD USER Income Limits API (US public domain).

Resolve a single IPv4/IPv6 address to its full network identity in one call: the Autonomous System number, the authoritative AS holder/operator (RIPEstat), the ISP + organization, whether the AS is currently announced, the RIR/IANA allocation block the AS sits in, and country/region/city + coordinates + timezone. One join that turns an IP into "who runs this network and where" -- the lookup network-forensics, abuse triage, and fraud agents otherwise stitch together from a geo API plus a separate BGP source. Composes geo IP data + RIPEstat (RIPE NCC, CC BY 4.0); the routing/holder block degrades independently, with per-source status returned. Distinct from net.asn (AS-number first) and geo.ip (geo only): this is IP-first and joins both.

A wallet's Polymarket on-chain activity feed: trades, merges, splits, redeems, conversions and rewards, newest first. Pass the wallet (proxy) address; optionally filter by type (TRADE/MERGE/SPLIT/REDEEM/REWARD/CONVERSION) and cap with limit. Each entry returns type, side, outcome, share size, price, USD value, timestamp, the market title/slug, conditionId, and tx hash. Read-only from Polymarket's Data API.
