Word of the day with part of speech and definition

Gas ONLY: live Base Mainnet gas from eth_feeHistory — latest and 10-block average base fee (gwei), priority-fee percentiles (p25/p50/p75) and a congestion label. Use this when you need gas and nothing else; if you also want WETH/USDC pricing, use market-snapshot instead (one cheaper call).

Returns recorded sale price and assessed value for one parcel, cited to the county assessor, for a last-sale or tax-roll check. Use this when you need assessed value and sale fields from the resolved official parcel. Use locus_parcel_lookup instead when you only need parcel identity, land use, acreage or year built.

Returns itemized tax-delinquency, tax-lien, and foreclosure rows near an address from official county, treasurer, and sheriff sources, for agents reading cited public records. Use this when you need itemized public lien records and citations. Use locus_tax_distress instead when you only need a nearby count and breakdown, without individual lien records.

EPA Map of Radon Zones county designation (1, 2, or 3) for an address, point, or state and county, for buyer, owner and lender agents. Returns the same records as locus_radon_zone. Use this when your client can only call paid x402 routes. Use locus_radon_zone instead when you can call Locus free tools (REST tools/call or MCP).

FEMA National Risk Index wildfire rating and score for the census tract at an address, for buyer, owner and lender agents. Returns the same records as locus_wildfire_risk. Use this when your client can only call paid x402 routes. Use locus_wildfire_risk instead when you can call Locus free tools (REST tools/call or MCP).

APT and dpkg Repair Guide — Linux & Systems

Multiplies per-contact transmission probability, effective contacts per day and infectious duration to obtain a simple basic reproduction number, then applies a susceptible fraction for an effective number. It is a classroom homogeneous-mixing calculation, not an outbreak estimate, fitted epidemiological model or public-health forecast.

Agent Tool Security Preflight — AI & Agents

FEMA NFHL flood zone, 0.2%-annual-chance and BFE/floodway flags at the geocoded point, for buyer, owner and lender agents. Returns the same records as locus_flood_zone. Use this when your client can only call paid x402 routes. Use locus_flood_zone instead when you can call Locus free tools (REST tools/call or MCP).

USGS stream and river gauges with latest stage and flow, plus NOAA/NWS threshold metadata within the search radius, for buyer, owner and lender agents. Returns the same records as locus_flood_gauges. Use this when your client can only call paid x402 routes. Use locus_flood_gauges instead when you can call Locus free tools (REST tools/call or MCP).

Is this x402 seller real? Pass ?seller= with a host (api.example.com) or a payTo address (0x...). From Coinbase's own Bazaar counts (re-read every 6 hours) we return its listings, 30-day payers and calls, and the one number that separates customers from a test harness: how many times the average payer came back. For an Arc payTo we add its settlements from our full Arc x402 index: distinct payers and the top payer's share.

Every signed x402-style payment on Arc since launch, read from the chain (plain USDC transfers carry no marker of what they paid for and are not counted): each EIP-3009 authorization spent on Arc USDC (AuthorizationUsed on 0x3600..., joined to the transfer it moved, in either of the two forms Arc logs it) and every Circle Gateway batch (net flows per address, decoded from submitBatch).

X1 chain (not Arc): top traders leaderboard ranked by NET XNT FLOW per wallet and token - XNT received from sells minus XNT spent on buys. It is NOT realized profit and loss: there is no cost basis, so a wallet still holding what it bought looks like a loser and one that sold an airdrop looks like a genius. The MCP twin was corrected on 2026-09-17 and this paid description was missed until the 2026-09-22 audit. For a cost-basis view use /api/x402/wallet, which prices the position proportionally.

Returns the same parcel-set facts as the free route for up to 25 addresses or jurisdiction-scoped parcel ids. Returns the same records as locus_parcel_set. Use this when your client can only call paid x402 routes. Use locus_parcel_set instead when you can call Locus free tools (REST tools/call or MCP).
