Summary

This connects Claude to blockchain-based data products on Base mainnet using the x402 pay-per-call protocol. You get access to three specific datasets: OFAC sanctions lists, METAR aviation weather reports, and US property records. Each query costs tokens on-chain, so you're paying for actual data retrieved rather than subscription access. Reach for this when you need real-time regulatory, weather, or property data in your workflows and want to pay only for what you use. The blockchain settlement means no API keys or traditional auth, just wallet transactions for each call.

Configuration

CORTEX402_WALLET_PRIVATE_KEY*secret

Private key (hex, 0x-prefixed) for an EVM wallet on Base mainnet holding USDC. Used to sign EIP-3009 transferWithAuthorization for each call. Easiest funding: Coinbase Wallet → Buy → USDC on Base network → debit card (~$5 covers ~50 calls).

CORTEX402_BASE_URL

Override the API base URL. Defaults to https://cortex402.vercel.app — only set this for staging or local development.

CORTEX402_MAX_PAYMENT_USDC

Per-call payment ceiling in USDC. Defaults to 5.00 (covers sanctions $0.50, aviation $0.10, property $2.00 with headroom). Raise if calling other x402 endpoints through this server.

huettentouren

philippvoss2212/huettentouren

Plan multi-day hut-to-hut hiking tours in the European Alps, powered by live availability data from the Alpine Club booking systems (DAV, ÖAV, AVS). ## What it does - Recommends curated multi-day routes filtered by difficulty, duration, number of hikers, and travel window - Returns bookable start dates only when hut availability is fresh (≤8h old) - Flags off-season requests, stale data, and no-match cases explicitly (no hallucinated suggestions) - Exposes full route detail: stages, elevation, overnight huts, booking URLs ## Tools - `recommend_tours` — rank routes by hard filters + soft preferences (months, transport, difficulty), return top matches with sample start dates - `search_tours` — fuzzy text search across route names and regions - `get_tour` — fetch full stage-by-stage detail for a single route ## Data notes Route content, stage descriptions, and hut names are in **German** (the primary audience is DACH hikers). Numeric fields, enums, and IDs are locale-neutral. Best used by agents that can either speak German or translate German strings downstream. Availability is aggregated server-side across multiple booking providers and exposed with a clear freshness contract — agents should not guess dates when `status != "bookable"`.
