A Polymarket trader's portfolio by wallet address: total portfolio USD value plus open positions (market title, outcome, size, average vs current price, current value, and unrealized PnL). For tracking a wallet's prediction-market book. Read-only from Polymarket's Data API.

The effective federal funds rate — the Fed's benchmark policy rate that anchors every other US interest rate — as a monthly average in percent, with the latest value, prior month, month-over-month and year-over-year change, and recent history. No ticker needed. The rate every rate-sensitive analysis starts from. Sourced from the St. Louis Fed (FRED). From x402stock

Look up or search NAICS 2022 industry classification codes (US Census Bureau, public domain). Pass `code` for an exact NAICS code — 2–6 digits or a combined sector like 31-33 — and get its official title, hierarchy path, full official description, activity index terms, and direct child codes. Or pass `query` for free-text search (e.g. 'software publishers', 'coffee shop') over titles plus the official ~20k-entry activity index → ranked candidate codes, optionally filtered by `level` (2=sector … 6=national industry). Ground truth for industry coding in KYC, business registration, government filings, and ERP vendor/customer setup.

Sanctions-screen a crypto wallet address against the US Treasury OFAC SDN list's published Digital Currency Addresses (BTC/ETH/USDT/XMR and more). Exact match — returns whether the address is sanctioned, and for any hit the listed entity name, OFAC programs, source id, and the currency the address was listed under. Compliance check before transacting. Distinct from crypto.address-safety (GoPlus behavioral risk) — this is regulatory sanctions.

Live prediction-market odds. source=polymarket (default) or kalshi. Polymarket: top active markets by 24h volume with outcome prices. Kalshi: open markets with yes/no bid-ask. Query: source, limit (1-50, default 20). Use for event probabilities, news signals, and cross-market arbitrage scans.

Discover the URLs a page or sitemap points at in a single fetch. Point it at an XML sitemap or sitemap-index and it returns the <loc> URLs; point it at an HTML page and it returns the <a href> links — auto-detected. URLs are resolved to absolute, de-duplicated, fragment-stripped, and http(s)-only. `limit` (1-2000, default 200) caps the count; `sameHostOnly` keeps only links on the same host. Single SSRF-guarded fetch, no JavaScript, stateless — NOT a recursive crawler: to go deeper, call map again on a child sitemap or a discovered page. Returns { url, finalUrl, source: "sitemap"|"links", count, capped, urls }.

Current spot price for crypto trading pairs. Input: pair — a single pair (BTC-USD) or up to 10 comma-separated pairs (BTC-USD,ETH-USD,SOL-USD) returned in ONE call for the same price — poll a whole portfolio per tick. Returns amount and currency per pair. Real-time from Coinbase.

Every DefiLlama yield pool, filtered and sorted server-side so you don't fetch the 11MB index. Query: chain, project, symbol, min_tvl (USD), min_apy (%), stablecoin (true/false), sort (tvl|apy), limit (1-100). Each pool: project, chain, symbol, tvl_usd, apy, apy_base, apy_reward, stablecoin, il_risk, exposure. APYs move — poll it.

Total DeFi TVL for every chain DefiLlama tracks, ranked. Query: limit (1-500). Each: name, tvl_usd, token.

Live order book for a crypto pair (e.g. BTC-USD). Default level=1: best bid/ask with sizes, mid price, spread, and spread_bps. level=2 adds top-of-book depth (depth param, 1-50 price levels per side, default 20). Real-time from Coinbase. Use for trading signals, spread monitoring, liquidity checks, and execution decisions.

Check accrued tollbooth earnings for a payout wallet: credits owed and USD equivalent. Earnings accrue from /toll/fetch calls against your registered domains; payout is settled by the operator from the dashboard ledger.

Current weather conditions for any coordinate worldwide. Pass lat + lon (and optional units=metric|imperial, default metric). Returns temperature, feels-like, humidity, precipitation (rain/snow), cloud cover, sea-level pressure, wind speed/direction/gusts, day/night flag, and a human-readable conditions label from the WMO weather code — with local time + timezone. Global coverage (not just US — for US-only NWS data see weather.zip / weather.forecast). Source: Open-Meteo (CC BY 4.0).

DeFi yield opportunities across chains and protocols (DefiLlama data): pool, project, chain, TVL, and APY, ranked by APY. Query: chain (e.g. Ethereum, Base), project, min_tvl (USD, default 10000000), limit (1-100, default 20). Use to screen for yield, monitor rates, and route capital.

Every DefiLlama protocol with current TVL, filtered server-side (the raw index is 8.5MB). Query: chain, category (Lending, Dexes, ...), min_tvl (USD), sort (tvl|change_1d|change_7d), limit (1-100). Each: name, slug, chain, category, tvl_usd, change_1d, change_7d, mcap. Use the slug with /llama/tvl for a live single-number poll.

Free-text search for securities across global exchanges via OpenFIGI. Give a query (company name, ticker, description) and optionally narrow by exchCode (e.g. US), securityType, or marketSector (Equity, Corp, Govt, Mtge, Muni, Pfd, Comdty, Index, Curncy). Returns relevance-ranked matches with FIGI, composite/share-class FIGI, name, ticker, exchange, security type, market sector, and description, plus a `next` cursor for paging (pass it back as start). Free, open symbology (Bloomberg OpenFIGI). Distinct from finance.figi (exact identifier → FIGI): this is discovery by name/keyword.

Stress-test a caller-supplied property price or assessment notice for one US address against cited recorded-sales, parcel, permit, hazard, tax, zoning, legislation, and same-roll assessment-uniformity evidence in protest mode; Locus never creates or endorses a price, ARV, deal judgment, or investment score, and the result is charge-free if under two substantive sections resolve. npx @velinussage/locus-agent-skill add.

Foresight API /v1/ask

EPA SDWIS drinking-water violations for a water system or area, for agents. Returns the same records as locus_drinking_water_violations. Use this when your client can only call paid x402 routes. Use locus_drinking_water_violations instead when you can call Locus free tools (REST tools/call or MCP).
